Jurassic World: Fallen Kingdom Trailer Coming In November?

Thursday, October 12, 2017

A new rumor suggests the first trailer for Jurassic World: Fallen Kingdom will be released in November of this year, around Thanksgiving. Of all the classic Hollywood franchise revivals that have been produced over the past handful of years, Jurassic World proved to be one of the most successful, breaking box office records en route to a $1.6 billion worldwide haul in summer of 2015. Obviously, Universal was keen on developing a sequel, and that followup will reach theaters next June. Chris Pratt and Bryce Dallas Howard are returning in their starring roles from the original World, and they’ll be joined by the one and only Jeff Goldblum as Dr. Ian Malcolm.

Director J.A. Bayona wrapped filming back in July, and is now making his way through post-production. As the highly-anticipated film inches closer to completion, fans are starting to wonder when Universal will start up their marketing campaign. At one point, it was speculated a teaser would debut at San Diego Comic-Con 2017, but that obviously did not come to be. Now, a new report is implying our first look at Fallen Kingdom will come in a couple of months – just in time for the holiday season.

Per Jurassic Outpost, it is believed the first Fallen Kingdom trailer will premiere around Thanksgiving. They caution that this is just a rumor for the time being, but mention Universal has informed their retail and licensing partners the Jurassic World 2 marketing campaign will “formally begin” that month. Some may recall the initial teaser for the first Jurassic World debuted in November 2014, so the studio is looking to replicate the advertising strategies they used to great effect the last time around.

From a business perspective, this timeframe makes a good deal of sense. Considering the reports are accurate, it’s very likely the teaser debuts during NBC’s broadcast of the New York Giants/Washington Redskins football game on Thanksgiving night. That would ensure the preview is shown to a massive audience, playing for millions of families gathered to celebrate the holiday. Universal would also then be able to attach a Fallen Kingdom preview to screenings of Star Wars: The Last Jedi, which is poised to dominate the box office in December. Awareness was never going to be an issue for a new Jurassic Park film, but it doesn’t hurt to kick off promotional efforts on this grand a stage.

As for what might be shown in the footage, fans should only expect snippets of information that offer clues about the plot. There’s still plenty of time until the film comes out, so all Universal has to do is whet the appetites of fans eager for another wild adventure with dinosaurs. It wouldn’t be out of the question to see the return of everyone’s favorite chaos theorist in a fun moment towards the end, letting casual audiences know early on that life found a way to get Goldblum back in Jurassic Park. He’s a fan-favorite character, so Universal would be smart to play up his involvement.

New Ichthyosaur Species Found in a University Storeroom – Where it’s Been for Over 50 Years!

Thursday, October 12, 2017

A new species of ichthyosaur has been identified from a fossil that has been in the University of Nottingham’s engineering collection for over half a century.

The University’s specimen, announced today as Protoichthyosaurus applebyi, is a holotype – the valuable original specimen that describes a new species. It is the first known fossil of its kind anywhere in the world, which makes it even more scientifically significant.

Dr David Large, a geologist and Head of the Department of Chemical and Environmental Engineering, who joined the University in 1995, had used the specimen for teaching and outreach work while visiting primary schools to encourage children to explore science and engineering. The fossil, which was a hit with children, had faded into obscurity and was forgotten about for years. However, it was rediscovered not long ago, sitting on a shelf in a storeroom. Recognising its rarity and uniqueness, Dr Large retrieved the fossil and his effort enabled palaeontologists and scientists to study the specimen in greater detail.

Dean Lomax, a palaeontologist and Visiting Scientist at The University of Manchester, contacted Dr Large in 2014 while searching for another ichthyosaur fossil and was unaware that the newly-found specimen even existed as it had not been scientifically examined before. Eventually it was determined that this specimen is of a species new to science. It has been hailed as a major step in uncovering Britain’s early fossil past and understanding ichthyosaur evolution.

Dean recently published his findings on the fossil in the Journal of Vertebrate Palaeontology in collaborationwith Professor Judy Massare of State University of New York, USA, and Rashmi Mistry, a former student at the University of Reading.

He said, “This ichthyosaur is an essential part of Nottingham’s scientific collection and I’d like to thank David for bringing it to my attention. As part of our study we have identified over 20 specimens of Protoichthyosaurus, but only one example of P. applebyi, making this the only known specimen recorded so far. I’m confident that there will be more out there. This particular ichthyosaur dates back to the Early Jurassic period and lived around 200 million years ago. As part of the wider study, Protoichthyosaurus has improved our understanding of the evolutionary changes in the forefins of ichthyosaurs, which set it apart from other species. This small- to medium-sized species would have probably been less than 2m in length, swimming in large numbers in the seas around Britain when the dinosaurs roamed the land.”

Professor Andy Long, Pro-Vice-Chancellor, Faculty of Engineering said, “I am delighted with today’s announcement that a new species of ichthyosaur has been discovered in the University’s collections. This is not the kind of thing that engineering faculties report every day and it’s the first time that our Faculty can claim to have discovered a new species. David’s passion for geology helped him to recognise the fossil’s importance. The Faculty has carefully restored the fossil and categorised it with information on what it is, where it came from and how it lived.

“We get visiting researchers from all over the world to share their expertise with our staff and students, including Dean and Judy who came to examine, photograph and document the specimen in greater detail. All these studies form the basis of a constantly growing research effort here at Nottingham.”

Dr Large added, “When I first saw the fossil, I knew it was special and I am delighted that Dean has confirmed just how special it is. A new species of ichthyosaur is exciting and this particular one is a unique example of its kind. The fossil was a great way to introduce a young audience to science and it got many children asking the right questions about palaeontology. I’m delighted that we saved the fossil and it’s been great to have the faculty’s support in bringing this specimen to a wider audience. We’re now using the latest technology to find out more about this unique animal.”

The University’s fossil is named after Dr Robert Appleby, the palaeontologist who first announced the discovery of the genus Protoichthyosaurus in 1979.

This ichthyosaur is now on display as part of the one-time only world exclusive Dinosaurs of China exhibition at Lakeside Arts. The exhibition emerged from the research carried out by Dr Wang Qi, an Assistant Professor in Architecture who specializes in exhibition and museum design.

There are plans for the fossil to undergo CT scanning to create detailed images which can be studied further in addition to casting and 3D printing to fill in the missing parts.

Mass Extinctions Led to Low Species Diversity, Dinosaur Rule

Thursday, October 12, 2017

Two of the earth’s five mass extinction events – times when more than half of the world’s species died – resulted in the survival of a low number of so-called “weedy” species that spread their sameness across the world as the Earth recovered from these dramatic upheavals. The findings could shed light on modern high extinction rates and how biological communities may change in the future.

David J. Button, an NC State and North Carolina Museum of Natural Sciences postdoctoral research scholar, and colleagues examined fossil records of almost 900 vertebrate species dating back between 260 and 175 million years ago – from the late Permian through the Triassic and early Jurassic periods. Two mass extinction events occurred during this time. Button says that similar patterns arising after two mass extinctions implies that other extinction events may have the same results – including current biodiversity loss.

“Mass extinctions not only reduced animal diversity, but also affected the distribution of animals and ecosystems, or biogeography,” Button said. “As species are removed by extinction, their ecological niches are left vacant. Following the extinction event, these niches are occupied by surviving and newly evolving ‘weedy’ species. These few generalists spread out and dominated for a time, leading to a low-diversity global ‘disaster fauna.’”

One of these generalists was the Lystrosaurus, a plant-eating early mammal relative that ranged from dog- to pig-sized. It had tusks to help it dig up plant matter.

The late- Permian event – occurring around 252 million years ago – allowed new groups to evolve, including the earliest dinosaurs, crocodiles and relatives of mammals and lizards, Button said. The late-Triassic event, which occurred around 201 million years ago, wiped out many major groups, setting the stage for dinosaurs to take over.

“The late-Permian event caused about 90 percent of sea life and 70 percent of land-living vertebrates to become extinct, probably as a result of climate change from hyperactive volcanism – when volcanoes spewed basalt lava and released gases into the atmosphere causing large increases in carbon dioxide and severe warming resulting in desertification,” Button said. “The late-Triassic event is also associated with volcanism.”

“Mass extinctions were global disasters that fundamentally reshaped ecosystems,” said Richard Butler, professor of palaeobiology at the University of Birmingham and a co-author of the study. “Our new analyses provide crucial data that show just how profoundly these cataclysmic events changed and influenced animal distribution.”

“The fossil record has the potential to test evolutionary hypotheses in long time spans, which is not possible if evolutionary research is limited to living plant and animals,” said Martín Ezcurra, a researcher at the Museo Argentino de Ciencias Naturales who co-authored the paper.

Identifying patterns across mass extinction events in the fossil record can help researchers make predictions about the consequences of current biodiversity loss, Button said.

“Further understanding of these ancient crises will help to inform conservation efforts to prevent modern animals from suffering a similar fate,” he added.

Spanish Paleontological Team Find Over 700 fish-eating Dinosaur Footprints in Portugal

Spanish Paleontological Team Find Over 700 fish-eating Dinosaur Footprints in Portugal

More than 700 fish-eating dinosaur footprints have been found in Portugal by a spanish paleontological team.

The dinosaurs were believed to be part of the Megalosauridae group, from the Middle Jurassic Period, and were thought to take advantage of low tides to hunt fish trapped in tidal pools, EFE news reported.

Novella Razzolini, the leading investigator on the Catalan Institute of Paleontology’s team, said the footprints were a “marvelous finding”.

She said the Middle Jurassic, which stretches back from 174 million to 163 million years ago, is known as the “dark age” of dinosaurs, as fossil records have shined little light on many of the creatures that lived during the period.

In Europe, most fossil remains from this group have been found in France, England and Scotland, while Portugal is known for the high amount of fossilised footprints.

According to the paleontologist, the footprints found are the largest in the Iberian peninsula and could belong to a small number of individuals that consistently fished in the area.

This is the first time investigators found clear evidence of migrations and movements by Megalosauridae with the sole purpose of acquiring food.

Rativates evadens: New Ostrich-Mimic Dinosaur From Alberta Named for Its Ability to Evade Predators

Wednesday, October 11, 2017

Rativates evadens

Dr. Michael Ryan of The Cleveland Museum of Natural History was part of an international group of researchers that announced the discovery of a new ostrich-mimic dinosaur, Rativates evadens, from the lower Dinosaur Park Formation near Dinosaur Provincial Park, Alberta. The new species lived about 76 million years ago during the Late Cretaceous Period. Research describing the new species is now published online in the Journal of Vertebrate Paleontology.

Based on a partial skeleton collected by the Royal Ontario Museum in 1934 from badlands adjacent to what is now Dinosaur Provincial Park, Rativates (RAT-iv-ATE-eez) would have resembled a modern ostrich, but with long, fingered arms instead of wings, and a long tail. It would have been approximately 3.3 meters (11 feet) long, about 1.5 meters (5 feet) tall and weighed about 90 kilograms (200 pounds).

Rativates was previously identified as another specimen of the more common ostrich-mimic dinosaur Struthiomimus altus, but lacks the key diagnostic characters of that species,” said lead author Bradley McFeeters, a Ph.D. student in the Department of Earth Sciences at Carleton University in Ottawa, Canada. “We can tell that it is a new species based on features of its skull, tail, pelvis and feet, including the shape of the long bones of the feet.”

Rativates (Latin ratis + vates) means “ratite (large flightless bird) foreteller” and alludes to the paradox of an ostrich-mimic dinosaur existing before ostriches. The name evadens means to evade, in reference to this swift-footed dinosaur’s ability to evade predators in the Late Cretaceous, as well as its recognition as a new species 80 years following the discovery of the original fossil.

“The referral of fossils to the named species of ostrich-mimic dinosaurs like Struthiomimus is complicated because many specimens are incomplete. The recognition of Rativates helps clear up these problems, and at the same time strengthens a connection between Canadian ornithomimids and their Asian cousins,” said co-author Dr. Michael Ryan, curator of vertebrate paleontology at The Cleveland Museum of Natural History, who was co-supervisor to the lead author.

Although it is a member of the carnivorous dinosaurs (Theropoda), ornithomimids such as Rativates lacked teeth and, similar to birds, had beaked mouths. They are believed to have been omnivorous, meaning they ate plants, insects and other small animals. Their long, powerful legs would have made them fast runners (like the Gallimimus in the original Jurassic Park movie), whether they were hunting prey or escaping from larger predators, like Gorgosaurus.

Although no skin impressions were found with the fossil, the closely related ornithomimid, Ornithomimus, also from Alberta, is known to have had a downy covering over most of its body. It may have had true feathers as well.

“We histologically thin-sectioned the femur of Rativates to analyze its growth and determined it was at least eight years old and nearly adult-sized at the time of death. This is only 80 percent as long, and half as massive as, the adult size of the closely related species Struthiomimus altus, that is estimated to have weighed approximately 175 kilograms (~385 pounds)”, said co-author Thomas Cullen, a Ph.D. candidate at the University of Toronto.

“This suggests that there are at least two differently-sized, but closely-related dinosaur species that lived together on the ancient landscape, similar to what we see today in the closely related predators like foxes, coyotes and wolves,” said McFeeters’ former co-supervisor and co-author Claudia Schröder-Adams, of the Department of Earth Sciences at Carleton University.

“Rativates is another exciting example of a new species of dinosaur being discovered among museum collections,” said Ryan. “These valuable collections allow modern researchers to build on the work of earlier scientists to advance what we know about the ancient Earth and provide new insights into evolution.”

Paleontologists Link Dinosaur, Bird Reproduction

Wednesday, October 11, 2017

A recent theory by paleontologists at Montana State University suggests that the nesting habits of some Mesozoic Era dinosaurs further bolsters the theory that all birds — from the majestic bald eagles of Yellowstone National Park to robins nesting in backyards across Montana — evolved from dinosaurs that lived millions of years ago.

“Reproduction in modern birds is distinct among living vertebrates and many aspects of this (modern bird) reproduction mode trace their origin to (Mesozoic Era) theropod dinosaurs such as Oviraptors and Troodontids, but not really beyond them to more distantly related dinosaurs,” said David Varricchio, associate professor of paleontology in MSU’s Department of Earth Sciences in the College of Letters and Science.

Varricchio said reproduction in the most common group of Mesozoic birds is very similar to that of these dinosaurs, and so still differs from modern birds. Consequently, modern birds stand apart from Mesozoic birds, and their more efficient incubation of eggs perhaps contributed to their surviving the end-Cretaceous extinction event, which led to the mass extinction of about 75 percent of plant and animal species on Earth.

In a paper published in August in the international journal The Auk: Ornithological Advances, Varricchio and MSU Assistant Research Professor Frankie Jackson examined the evolution of bird reproduction through a series of distinct stages, from pre-avian dinosaurs to the birds of today.

“We found Troodon formosus to have many avian attributes, but still differ from modern birds,” Varricchio said of the Montana dinosaur with serrated teeth that weighed around 100 pounds.

Troodons share many reproductive traits with modern birds, such as having a hard-shelled egg. However, according to Varricchio, troodons differ reproductively from modern birds in several ways, too. One of these ways is that they partially buried their eggs in the sand or earth, rather than nesting wholly on top of the surface. The most abundant birds of the Mesozoic, called Enantiornithines, still buried their elongated eggs, at least in part, as did the troodons, Varricchio said. Modern birds were the first to lay the familiarly shaped eggs we know today and incubate them without any burial within sediment, which scientists believe improved the efficiency of brooding and may have been important to their ultimate success as a species.

“This tells us something about how those particular dinosaurs reproduced,” Varricchio said. “We can’t ask why they evolved that way without knowing when those traits evolved and under which conditions they evolved. We need the historic context.”

In an unorthodox move, Varricchio and Jackson chose to publish their work in The Auk, an international journal pertaining to birds, rather than in a paleontological publication, in an attempt to work toward a consensus that has divided scientists in the respective disciplines.

“Ninety-nine percent of paleontologists believe that all modern birds are dinosaurs, but, there’s still some resistance from ornithologists on that point,” Varricchio said. “People have argued about the bird-dinosaur connection since the 1800s. But, since then, there has been overwhelming skeletal evidence [to support the connection]. Then in 1996, we learned that some dinosaurs had feathers. Well, their reproduction follows that pattern, as well.”

According to Varricchio, ornithologists point to a limited sample size of specimens to cause them to rethink fully the fundamentals of their field of study.

“There’s a pretty good record of how reproduction evolved from dinosaurs to modern birds,” he said. “It’s more of them seeing holes in the data sets or a lack of specimens, which is a pretty good argument. We might have one or two specimens rather than hundreds—and that’s a fair argument.”

Triopticus primus: Scientists Shed Light on Bizarre Dinosaur Having Bony Domed Head

Wednesday, October 11, 2017

On the basis of a fossilized partial skull excavated in 1940 near Big Spring, Texas and then remained in drawer in a University of Texas paleontology collection, scientists have discussed about a bizarre dinosaur named Triopticus primus.

Around 228 million years back, this dinosaur used to live in a warm, lush region of West Texas. Factor that separates this dinosaur from others is its bony domed head, composed of thickened bone. As per scientists, other animal having such comparable craniums were dinosaurs known as pachycephalosaurs that were present around 90 million years back.

The researchers have found similarity in the internal structures of Triopticus and pachycephalosaurs skulls. Earlier, the researchers were confused as what for purpose pachycephalosaurs used their heads and now, they have same uncertainty for Triopticus.

Study’s lead researcher Michelle Stocker was of the view, “It’s difficult for us to say what the domed morphology would have been for or what would have ‘encouraged’ the evolution of this structure”.

Triopticus as per the researchers is an interesting example of evolutionary convergence as the unique body shapes found in many dinosaurs have evolved million of years back in the Triassic Period. According to the researchers, the dinosaur might have been around 10 feet long.

The researchers are not exactly clear on whether Triopticus walked on two legs or four and it is also known whether it ate plants or meat. The dinosaur was present when the very first dinosaurs were actually appearing.

Katharine Criswell, evolutionary biologist at University of Chicago, said that it is quite amazing to know that many of the iconic dinosaur features have arrived independently up to 100 million earlier in the distant reptilian cousins.

According to a report in CS Monitor by Eva Botkin-Kowacki, “Stocker and her colleagues came upon the skull when sorting through specimens collected across Texas by the Works Progress Administration in the late 1930s and early 1940s. “We were just going through the drawers and found this blob, essentially,” she recalls in a phone interview with The Christian Science Monitor”

New, but also familiar. When the paleontologists began to examine the skull, they quickly noticed the remarkable thickness of the roof of the skull. The dome-shaped skull struck them as particularly similar to those of animals that lived about 140 million years later: the pachycephalosaur dinosaurs.

Instead, the specimen was a relative of dinosaurs and crocodilians, Stocker says. And that means this is a prime example of convergent evolution, a process by which two different animals independently evolve a similar feature. The team dubbed the extinct animal, Triopticus primus, in a paper describing the specimen published Thursday in the journal Current Biology.

A report published in VOA NEWS informed, “In a warm, lush region of West Texas crisscrossed with rivers, a bizarre reptile roamed the Triassic Period landscape about 228 million years ago, boasting a bony domed head unlike almost any creature that ever appeared on Earth.”

Even the internal structure of Triopticus and pachycephalosaurs skulls was similar. There has been a long debate among paleontologists about how pachycephalosaurs used their heads, whether for head-butting like bighorn sheep, self-defense or some other purpose.

“It’s difficult for us to say what the domed morphology would have been for or what would have ‘encouraged’ the evolution of this structure,” said Virginia Tech paleontologist Michelle Stocker, who led the study published in the journal Current Biology.

Here’s How the ‘Jurassic World’ Dinosaurs Looked in Real Life

Wednesday, October 11, 2017

It is well-known at this point that “Jurassic World” diverges from the science when it comes to its portrayal of dinosaurs.

In real life, many of the dinosaurs vary in size and are often covered in feathers, but a few of them actually don’t look that different.

Let’s start with Velociraptor, one of the most feared creatures in the “Jurassic Park” universe:

In reality, the Velociraptor could be more easily compared to either a turkey or a coyote:

Velociraptor was much smaller in real life. Luis Rey

The look of Velociraptors in the film was actually based more off of Deinonychus

… as well as a Utahraptor which was discovered as the original “Jurassic Park” was being made:

One of the most terrifying new dinosaurs introduced in “Jurassic World” is the Mosasaurus, which makes even a great white shark look tiny.

The real Mosasaurus isn’t actually a dinosaur and it didn’t have spikes along its back.

Early fossil findings misled Victorian artists when Mosasaurus was first discovered. This sketch is more in line with the modern view of Mosasaurus. Dmitry Bogdanov via WikiCommons

The Mosasaurus is really “marine lizard that’s more closely related to snakes and lizards,” according to Dr. John Hutchinson.

After making a brief cameo in “Jurassic Park,” the Gallimimus returned for “Jurassic World”:

The real Gallimimus was actually fairly similar, but with a lot more feathers.

Gallimimus had a strong physical resemblance to an Ostrich, which is probably why it runs very similar to one in the films. Steveoc 86 via WikiCommons

Here is a Pteranodonthe unlucky victim of the much larger Mosasaurus:

And here’s a sketch of what the winged animal (who isn’t actually a dinosaur) probably looked like:

The flying Pteranodon was actually not a dinosaur. Luis Rey

The Pteranodon was actually a Pterosaur, which is “a winged reptile which is very, very, very closely related to dinosaurs but not a dinosaur,” according to Hutchinson.

And finally, there’s the almighty T. rex:

The real T. rex was still huge, but it was actually covered in feathers. 

Public knowledge and perception of T. rex has changed immensely since “Jurassic Park” was released in 1993. Durbed via Wiki Commons

Some have jokingly compared the T. rex to a “giant chicken.” But still, would you want to mess with it?

Do You Know How the Dinosaurs Look? Scientists Present the Most Accurate Reconstruction

Wednesday, October 11, 2017

What do you know about dinasaurs? Are they new to our planet? How the dinosaurs looked like?

Do you how dinosaurs looked like in the ancient times? Well, it was only a few millions years ago, and most of us should remember, right? Unfortunately, new discoveries provide us the information that we were wrong mostly about dinosaurs. Recently forty researches from various institutes of the world were amazed at new dinosaurs. These forty men with doctorate degrees were staring at the new version like children in a candy shop. Paleontologists and paparazzi couldn`t miss a chance of gathering and snapping a new creature standing in front of them. They couldn`t hide excitement with all their approving nodes and discussing the matter.

From the first glance to the dinosaur, it looked like a Frankenstein monster. Only the fiction monster was created out from the bodies of the humans, this on represents a synthesis of reptile and birds. Some people may find the resemblance of the monster with a turkey or parrot. Especially, the parrot-like face. Nevertheless, this parrot was certainly dangerous as it could harm you not only with words. Scientists gathered to look at this miracle of nature to understand the nature of evolution process. Nevertheless, some research couldn`t hide their curiosity by touching bristles erupted from the tail of the creature.

Paleoartist Bob Nicholls presented this new creature. His genius mind could construct the new type of reconstruction of Psittacosaurus. Scientist and regular people saw dinosaurs before, so what is the new with this version of died ancient creature? Nevertheless, the reconstruction of Psittacosaurus is claimed the most accurate for the whole history of paleontology. It connects almost all pointy features of the old creature. Bob Nicholls based his reconstruction on the studies of Dr. Jacob Vinther from the University of Bristol in the UK. The discoveries of this scientist in China helped the paleoartist create the most accurate version of the dinosaur.

If you did not know much about dinosaurs or you don`t have a whimsy child who helps you get some information about the ancient creatures, then you would need to be answered in some FAQ. Psittacosaurus fossil (the fossil which helped to reconstruct the Psittacosaurus) can be found in the most of Asia, particularly in China and Mongolia. One of the distinct features of Psittacosaurus is its large brain. The dinosaur lived around 100 million years ago, but the size of the brain can also suggest that it was one of the smartest dinosaurs.

Photographs of Nicholl’s exquisite life-size model, the “most accurate dinosaur reconstruction ever!”

This specimen was held and researched at the Senkenberg Museum in Frankfurt. The lead research group in the studying of the dinosaur was Vintner’s team. The complete skeleton of Psittacosaurus was delivered to the facility from China for complete studying of the matter. Now it`s stored in Frankfurt in one of the most secured fossil deposits in the whole world. This storage place is called Lagerstätte. This storage is famous for reasons of researches and containing large deposits of fur, stomach, skin, feathers and bodies of different ancient animals. Nevertheless, even among these fantastic creatures, the Psittacosaurus is a star, especially with preserved cloaca.

Vintner’s team are no strangers to the storage in Frankfurt. Vinther is a famous scientist – paleontologist, especially with its last discoveries of Sirius Passet in Greenland. In the paleontology science, his name becomes a synonymous of fossil pigments studying. He was the leader in studying of fossil remnants from various parts of the world, like Brazil, China, and Germany. He managed to travel in almost all parts of our small planet to make discoveries out of the little remnants, like ancient squid ink or avian dinosaurs feathers. This man can be named a rock-star of paleontology in some way.

It`s no secret that there were studies of the Psittacosaurus before. Nevertheless, the Vintner’s team was the first one who approached to the studying in a more quantitate way. They managed to reconstruct the accurate pigments of the skin. They approached the researching of the remnants with X-rays and highlight fluorescent materials to create an accurate version of the dinosaur’s skin. They used electron microscopes to find parts of melanosomes. This hardly to pronounce word`s meaning defines as the structure of pigments gathered in skin and skin cells. Therefore, from “Ashes,” they managed to create a 3-D version on the computer of Psittacosaurus. That was the time for Robert Nicholls to came in the game.

Robert Nicholls is based in Bristol, and he is famously known for his artworks with dinosaurs’ recreation. His vivid artworks in Paleontology are famous in the world of science. His portfolio works can be seen in various famous channels on TV, like National Geographic and BBC. Various museums have the honor to show his artworks. He breathes a new life into a prehistoric world with his art creations. Moreover, he does not lack a sense of humor; you may know his necks are acting like rods of lightning from a sauropod, and especially famous dinosaur suffering from dysentery. Robert Nicholls have his vivid vision the prehistory world.

In one of his interviews, where he tried to remember when he had started his work with dinosaurs, he pointed at the childhood. We all liked drawing dinosaurs in childhood, but rarely one of us could imagine this kind of hobby like a profession.  Nevertheless, Robert Nicholls was one of the guys who decided to continue drawing dinosaurs as a full grown man. In the question about Psittacosaurus, he managed to get some information about this kind of creature from Jakob. One phone call was enough to get the interest of the artist in work with Psittacosaurus. Therefore, now we have the most accurate model of this dinosaur.

The reconstruction process took around three months of work, but it was the very culmination of the process of recreating as there was no turn back. In the very basis, it was needed to create a fiberglass model. Nicholls firstly created a frame made of steel and with using of polystyrene and wire mesh bulked the whole construction. It was a necessary process, before sculpting the model in clay. That was the exact point when the figure comes to life with adding skin features, wrinkles, horns, and beaks. The master mold was created out of this sculpture. Therefore, it allowed Nicholls to paint the fiberglass model.

What is so special for Nicholls in creating this sculpture? For him, it`s an unusually large head with pigment clusters, robust limbs, skin flaps, and highly pigmented cloaca. Nevertheless, this features supported the idea of the most accurate feature of the dinosaur in the whole world. For Nicholls, the whole surprise was the anatomy of the creature, especially with cloaca. Still, these features can be complete evidence of the most exclusive dinosaur pattern in the world. Therefore, it was needed to be created and showed to the public. Nicholls was the only master who could create such a creature in a three-month period.

The Psittacosaurus recent researches showed more than mere deep skin pigments. The dinosaur takes its name from the Psittacines, in other words – parrots. This ancient creator was an ancestor of these smart little birds. Nevertheless, it`s still questionable. In 2010 a paleontologist Paul Sereno argued the parrot-like patterns of the Psittacosaurus, he stated that this dinosaur is an ancestor not only to parrots but the whole group of birds. Nevertheless, his statements were discussed once later with the new discovery of muscle types of parrots and the Psittacosaurus which are not seen in every other bird or reptile.

Still, more scientist can argue the family connection between Psittacosaurus and parrots. Adam Taylor from the University of Bristol argued the statement of the similarity of muscle types of these family members. Moreover, he seems to argue The Anatomical Record of the creature. Adam Taylor states that the too soft facial features of the dinosaur are taken so far. His team modeled a different type of the dinosaur. With using a new method of engineering which is called finite element analysis FEA, they managed to test the skull of the bird-like dinosaur during the feeding. Therefore, they could see that the muscles during feeding process act not similar to parrots.

Nevertheless, the Psittacosaurus may not be a creature which has a resemblance with a dazzling parrot of the Mesozoic era, but Vintner’s team still made a discovery by revealing so many features of the prehistoric creature. These detailed studies of the Psittacosaurus showed us how these creatures lived, who were their natural enemies and the food they ate. Moreover, scientists can analyze the lifestyle of that animals with modern animals to see some resemblance of the ancestors and their modern offsprings. The complete study of the Psittacosaurus can show some distinct patterns of lifestyle in the whole family group of gazelles in African’s Savanah.

According to recent studies, the Psittacosaurus lifestyle was more like gazelles in African’s Savanah. They could dwell in open space, moreover, like gazelles, the Psittacosaurus had darker backs and lighter bellies. This ancient dinosaur had something called countershading, the ability to blend in the environment. It means that they were perfect masters of leaving the danger when it was needed and blend with the environment. People also have the same patterns in modern military and hunting equipment. Of course, they were made by hands of people, not by design of Nature, but people can learn from Nature and continue learning.

According to Vinther, the coloration can show the scientist a dynamic between prey and predators. It`s an important strategy regarding victims and hunters in the modern world. How it was possible that they distinguished so differently is still a secret for lots of scientists. It`s still unclear why they managed to develop in some or another way. Nevertheless, the remnants of the Psittacosaurus and other creatures of that period can give the answer to the scientists. Why preys got his pigmentations with more like terrain scale, while predators have a completely other pigmentation. What was the whim of nature to act like this in some manner?

The Psittacosaurus skin was examined several times during researches. The scientist tried to play with a different pattern of possible skin color and shapes for this creature. Nevertheless, this kind creature had not only a specific skin color but also shades of this color, which helped him blink on the sun in some manner. Therefore, the predators could notice it from the distance or be blinded by the sun from the skin of Psittacosaurus. Vinther tried to examine this kind of patterns of the animal by laying the gray model without patterns, to understand how shadows fall on the body of the dinosaur.

This photographed light diffusion provided by the paleontologist helped to reconstruct the exact model of the Psittacosaurus and also provide a skin model for the exact dinosaur. This fossil can provide some images and patterns of life of this magnificent creature. Nevertheless, even with a whole model of the dinosaur created by a paleontologist artist, the humanity still has a little understanding of life not only this specific creature but the whole Era where it lived. Therefore, you can expect a lot of studying in the further years.

There are still interesting facts about this Psittacosaurus. It had feathers and supposedly could dwell not only on the ground but also on the trees, like birds. It couldn`t fly obviously but still desired to create some manner of flying in other modern birds. The camouflage pigmentation on the body could provide some manners for protection, but not for the whole. There was still opened mouth features for this type of animals, which might have been the main spot for predators. Nevertheless, it helped the Psittacosaurus to chew food they needed.

The scientists like Vinther and his team does not desire to stay on this level of studying of the Psittacosaurus. It seems that the dinosaur has some connection with modern parrots and gazelles, but there is a still clear not understanding of how it should work. There are a lot of evidence that there may be similarities to both of these creatures. Nevertheless, there is still some doubts about the Psittacosaurus being one of those creatures’ ancestors. The main problem, for now, is the type of their jaw muscles. They might be similar to a parrot, but still, it`s not enough to prove their relatives’ connection.

Vinther and his team are no strangers to scavenging discoveries out of the fossil. The research work made by the team of scientists and especially the work of the most accurate version of the Psittacosaurus may show people the real understanding of dinosaurs. Moreover, the discovery of Nicholls shows that now that day when every paleontologist could create some colors for the dinosaurs is gone. There are many pieces of evidence of colors of dinosaurs. The new age of technology showed the importance of colors for everyone in this matter. Therefore, Nicholls can clearly look to the bright future side of the question.

So, what is for Vinther? After his travels and his work with the Psittacosaurus, what should we expect next? According to his words, he would still continue working with ancient creatures. His next target is mammals from Messel period of our history. Nevertheless, it does not mean that he would live his work with dinosaurs. There are a lot to do with these majestic creatures.

So, when your child asks you about the most accurate dinosaur model, you can show them the picture of the  Psittacosaurus, which is the most actual model for dinosaurs.

The Case for De-Extincting Ice Age Megafauna

Ice Age Megafauna

Humans helped kill off the giant animals of the Ice Age. We owe it to the ecosystem to restore what we destroyed.

What if human beings had the power to take an animal that was completely extinct, and bring it back using only the DNA it left behind? We are actually talking about creatures who lived much more recently than dinosaurs, even if it all feels like the distant past to us. What if we brought back extinct Ice Age animals?

The last ice age ended 11,700 years ago, and with it went a lot of really fantastic large mammals — known as “megafauna” — that were bigger in stature than their modern-day counterparts. Mammoths and saber-toothed cats roamed the Earth, but also mastodons, cave lions, giant ground sloths and a giant armadillo-like creature called the glyptodon.

All of these animals have one major thing in common. Unlike the dinosaurs in “Jurassic Park,” these Ice Age mammals coexisted with humans, and many were hunted by our ancestors too. If humans played a role in their extinction, the case for bringing them back is more compelling. De-extinction efforts often draw critics who accuse scientists of “playing God,” but many disagree. Speaking about the efforts to bring back a wide variety of creatures, paleontologist Michael Archer has said, “If we’re talking about species we drove extinct (sic), then I think we have an obligation to try to do this … I think we played God when we exterminated these animals.” An argument can be made for trying to “resurrect” some of these creatures, and there are scientists willing to try.

De-extinction is just what it sounds like: taking a species that has gone extinct, and through cloning or genetic engineering, bringing that species back into our world. Technically, de-extinction has happened once, albeit briefly: The bucardo (a goat-like creature) went extinct in 2000, and was successfully cloned in 2003 and born via a surrogate goat mother. However, the lone cloned bucardo suffered from breathing issues (common in early cloning efforts) and only lived 10 minutes. This might sound gloomy, but we’ve made a lot of advances since 2003, and the bucardo’s case proves that de-extinction is indeed possible.

The bucardo wasn’t an Ice Age megafauna, but the woolly mammoth certainly was. According to Revive & Restore, an organization focused on “genetic rescue of endangered and extinct species”:

The Woolly Mammoth has emerged as a leading candidate for this work. It can be attempted because a close relative of the mammoths still lives–the Asian elephant. Thanks to the similarity of their genomes, the genes of woolly mammoth traits can be edited into the Asian elephant genome, and the combination brought to life as an elephant cousin, once again adapted for the conditions of the far north.

The possibility of bringing back the mammoth might seem like a curiosity. Wouldn’t it be fun to see a woolly mammoth in a zoo? But the long-term goal is not to keep the new mammoths (they would be genetically engineered approximates, not exact replicas) in captivity. Instead, the Harvard Woolly Mammoth Revival team headed by George Church (the Church Lab) hopes to one day release healthy herds of mammoths into the tundra of Eurasia and North America. The reintroduction of these grazers could help convert the tundra back into the mammoth steppe, or grasslands, it once was. Research suggests grasslands sequester carbon from the atmosphere more efficiently than other ecosystems, which could help slow down climate change. Along the way, Church and his team expect to learn things that could help with the conservation efforts for Asian elephants.
