Shedding pet dinosaurs

Q. Did dinosaurs peel or shed their skins?

A. Presumably, said Mark A. Norell, chairman of the division of paleontology at the American Museum of Natural History. But not all at once.

“Since we can’t directly observe extinct animals, we need to look at close relatives,” Dr. Norell said. “Birds are living dinosaurs, crocodilians their closest relatives. Both shed skin in patches and strips, not entire skins like snakes.

“Because crocodiles and birds share a common ancestor, we predict this skin-shedding style was present in that ancestor,” he continued. “Nonbird dinosaurs descend from this same ancestor. Without other information, we predict that even giant dinosaurs exfoliated their dead dry skin in patches.”

Everything that has skin sheds it, Dr. Norell emphasized, but there is a tremendous diversity in how skin sheds. In humans, for example, rubbing the dry skin of an arm across something black leaves a white scuff of dead skin cells, he said. And in birds, skin dries and sloughs off as small patches, like peeling after a bad sunburn.

Reptile shedding usually conjures visions of whole snakeskins, shed as a continuous piece, “looking like the ghost of a living serpent,” Dr. Norell said. But this is an anomaly; most animals do it differently. Typical reptiles — lizards, crocodiles and turtles — shed dry, irregular skin patches, and that is probably how dinosaurs did it, he said.

How Bird Beaks Got Their Start As Dinosaur Snouts

Scientists say they have reversed a bit of bird evolution in the lab and re-created a dinosaurlike snout in developing chickens.

"In this work, we can clearly see a comeback of the characteristics which we see in some of the first birds," says Arhat Abzhanov, an evolutionary biologist at Harvard University.

The ancestors of birds are a group of dinosaurs that includes the famous velociraptor, Abzhanov says. This group of meat-eaters had long snouts, small brains and eyes, and lots of teeth. Somehow they transformed into birds, which have none of those things.

Bhart-Anjan Bhullar, another member of the research team at Yale University, says the goal is to understand exactly how birds became birds. "What's the deep history of birdiness?" wonders Bhullar. "How did the different parts of their body plan form?"

In particular, he and his colleagues are interested in birds' distinctive beak, which Bhullar calls "this insane sort of snout that they have."

To hunt for clues about the origin of the beak, the researchers have been studying various kinds of animal embryos, from birds like emus and chickens to nonbird reptiles like alligators, which are birds' closest living relatives.


Their work led them to two specific genes. These genes are active in the middle of the face-forming region of bird embryos, but not in the middle of that region in the embryos of other animals.

The team did an experiment to see what would happen if they blocked the effect of that localized gene activity in chicken embryos.

Bhullar says he remembers the night he put the altered, developing chicks under a microscope, and saw that they had unusual, broad snouts.

"That was a pretty remarkable moment," he recalls. "That's a moment that will stay with me, I think."

Kids Bring Box of Poop to American Museum of Natural History

Bed Bugs & Fossilized Dinosaur Poop Surface At AMNH's Identification Day

Once a year, kids with bubble-wrapped bones and sandwich bags full of nubby rocks crowd around precision-lit folding tables in the American Museum of Natural History's Theodore Roosevelt Memorial Hall.

"We put this day on the calendar," said Caitlin Trasande, whose sons Camilo, 6, and Ramiro, 5, had just learned that the rocks they collected at Lake Taghkanic last summer contain 450-million-year-old marine fossils. "We were waiting and waiting for this day to come." Camilo, especially, couldn't believe it. "This was a flat snail that lived!" he shrieked, jumping up and down. "A brachiopod is a filter-feeding animal that usually lives in shells! You can see the imprint of the snail itself!"

Nearby, Entomologist Lou Sorkin held a sealed pill bottle of living bed bugs up to the light. A tiny camera projected the bugs onto a flat-screen television behind him. Sorkin studies bed bug infestations within New York apartment buildings, and he'll proudly show you the raw, red patch of skin on back of his hand where he lets them feed. Yesterday, he helped a nervous New Yorker identify a picture of a biting bug from her apartment. It was a mite.

On Identification Day, museum-staff Anthropologists, Paleontologists, Zoologists, and Ornithologists invite New Yorkers to bring in puzzling shells, artifacts, rocks, and occasionally insects and feathers. Equipped with magnifying glasses and comparison specimens from the museum collection, they start by asking for context—where did this bone come from? Did you find it on Rockaway Beach, or did you buy it on eBay? Paleontologist Carl Mehling admits that, "More than fifty percent of the time it's pure imagination. Someone will come in and say, 'This looks like a dinosaur skull!' But it's just a rock. When I hear something fantastic like that, I'm already concocting my gentle letdown."

That was the case for Joey Rosado and his son Javier, who like to visit Coney Island the day after a big storm, to collect bones and rocks that get spit out onto the sand. Javier handed over two sharp bones that he hoped came from a dinosaur. But Mehling quickly identified them as "left-over barbecue," citing the clean-cut edges that could only come from a bone saw.

There are exceptions, though. A few years ago, a woman showed Mehling a skull that she had found on the beach in Virginia. "Immediately I could see that it was part of a walrus skull. I knew that it couldn't be modern, because walruses today are strictly arctic. The skull is probably tens of millions of years old." And yesterday, even Mehling was surprised when a shoebox full of fossilized dinosaur poop landed on his table. Bridget, who lives in Manhattan, found the poop on a construction site when she was traveling in Berkshire, England.

Poop is one of Mehling's specialities, and it's notoriously hard to identify. "It's really, really hard to know what kind of animal fossilized poop came from, because, unlike a body part, poop doesn't have to look a certain way," he explained. "And when a creature poops, it's not obligated to hang out and die right next to it."

Dinosaur Feathers Discovered in Canadian Amber

Today a group of paleontologists announced the results of an extensive study of several well-preserved dinosaur feathers encased in amber. Their work, which included samples from many stages in the evolution of feathers, bolstered the findings of other scientists who've suggested that dinosaurs (winged and otherwise) had multicolored and transparent feathers of the sort you might see on birds today. The researchers also presented evidence, based on the feathers' pigmentation and structures, that today's bird feathers could have evolved from dinosaur feathers.

We've got a gallery of these intriguing feathers preserved in amber.

In a profile of lead researcher Ryan McKellar, The Atlantic's Hans Villarica writes:

These specimens represent distinct stages of feather evolution, from early-stage, single filament protofeathers to much more complex structures associated with modern diving birds... They can't determine which feathers belonged to birds or dinosaurs yet, but they did observe filament structures that are similar to those seen in other non-avian dinosaur fossils.

Villarica also did io9 readers a favor and asked McKellar whether this discovery could lead to a Jurassic Park scenario. McKellar said:

Put simply, no. The specimens that we examined are extremely small and would not be expected to contain any DNA material. To put this into context, the only genetic material that has been recovered from amber is from lumps of mummified insect muscle tissue in much younger Dominican amber that are approximately 17 million years old and well after the age of dinosaurs.

So much for our dreams of dino domination.

5 Year Old Paleontologist Digs Dinos, Literally

This 5-year-old who found a rare dinosaur fossil in Texas is living his best life

On Wednesday, I realized I was not a cool 5-year-old. I suppose I always knew this.

Sure, I did cool things. I mean, I climbed trees and jumped in puddles and was generally pretty into Cardinals baseball and also sno cones. And that all sounds well and good.

But then I read this story about 5-year-old Wylie Brys, who — with his dad — discovered a dinosaur fossil, which is being excavated this month in Mansfield, Tex.

And now I'm forced to admit that my 5-year-old self was definitely not that rad. Not even close. Wylie Brys is straight crushing childhood.

Wylie goes poking around for fossils fairly regularly with his father, Tim Brys, who works at the Dallas Zoo. This particular find happened on land behind a suburban shopping center, not far from a grocery store.

On this trip, Wylie walked up ahead of his dad, Tim Brys told The Post in a telephone interview. When he came back, Wylie had a chunk of bone with him. Tim Brys asked his son to show him where he found it.

"My dad told me it was a turtle," Wylie told the Dallas Morning News. "But now he's telling me it's a dinosaur."

Said his father of the find: "It was a pretty good size and I knew I had something interesting."
Southern Methodist University scientists believe the fossil may be about 100 million years old.

A Century Later, Beloved Brontosaurus May Reclaim Its Name

Brontosaurus is back, baby!

Generations of schoolchildren have learned that a massive, long-necked dinosaur called Brontosaurus once roamed Earth. But in fact, scientists dropped that name more than a century ago -- referring to it as Apatosaurus instead.

Now, after a thorough analysis of dozens of long-necked specimens, a team of British and Portuguese paleontologists says it's time to revive the old name.

"It's the classic example of how science works," study co-author Dr. Octavio Mateus, a paleontology professor at Universidade Nova de Lisboa in Portugal, said in a written statement. "Especially when hypotheses are based on fragmentary fossils, it is possible for new finds to overthrow years of research."

The backstory. Starting in the 1870s, rival paleontologists Othniel C. Marsh and Edward D. Cope were scouring the American West, competing to find new dinosaurs in what became known as the "Bone Wars."

During Marsh's digs, his team found two incomplete skeletons of massive, long-necked sauropods. Based on one of the skeletons, Marsh announced the discovery of a new dinosaur called Apatosaurus ajax, the "deceptive lizard" in 1877. Then, two years later, he described the second skeleton as belonging to another new species called Brontosaurus excelsus, the "noble thunder lizard."

But after paleontologists collected a specimen with features similar to both Brontosaurus and Apatosaurus, they said the two dinosaurs were too similar to belong to separate genera. And so in 1903, Brontosaurus was re-classified as Apatosaurus excelsus.

A second look. For the new analysis, the researchers spent five years examining the scans and fossils of 81 sauropod specimens. Then they conducted statistical analyses to discover how much the dinosaurs differed, based on 477 specific features, Scientific American reported.

"Our research would not have been possible at this level of detail 15 or more years ago," Dr. Emanuel Tschopp, a paleontologist who led the research while completing his PhD at the Universidade Nova de Lisboa, said in the statement.

Computerized CogniToy dinosaur is the latest smart toy for kids

MIDTOWN, N.Y. --

It may look like a mini robot dinosaur, but there is a new generation of smart toy from which your child can learn.

Wirelessly connected to the internet, the toy initiates and engages in real conversations with your childm powered by IBM's computer wizard "Watson" for cognitive computing.

The so-called smart toy, or CogniToy, is personalized to your child, and there are parental controls to monitor your child's progress.

"A 5-year-old can ask 100 questions a day," co-founder JP Benini said. "What if this thing never gets tired of answering 'why?' That's what the idea started with."

The company, Elemental Path in Midtown, put out a promotional video on Kickstarter to raise capital for the line of CongniToys.

"It not just has the ability to answer questions, but play educational games, tell stories, and even light conversational dialogue," Benini said.

Working with a prototype that could be offered in three colors, Benini and Sean O'Shea, two of the four co-founders, decided to make the smart toy utilizing 3-D printer technology.

"There are not many things that are universally appealing than a dinosaur," Benini said.

Design changes evolved from there into the current toy.

"When kids drag around that one toy that they love, they give it the name," Benini said. "They name their imaginary friends. Why not name their virtual dino friend?"

The toy, company officials stress, is designed for engaging play experiences and to grow with each child.

"We're not trying to replace parents, teachers, or tutors," Benini said. "We're just trying to give a supplemental source."

Bones and Tensegrity

Tensegrity is a 60's term coined by Buckminster Fuller that inspired Kenneth Snelson to make monumental artworks with cable and tubing, but the principles are building blocks for more than just pop sculpture. When applied to bones, some interesting origins of tendons and locomotion can be inferred. This is especially interesting to me when looking at naked bones of dinosaurs. Which bone is connected to which other bone? What did they look like with tendons holding muscle to bone? How did they get around? How did their skin stretch?

Check out some cool bone tensegrity models here and here.

Did Dinosaurs Have Lips?

Paleoartist Puts a Face on Ancient Bones

 

CHICAGO—After careful consideration, Tyler Keillor made a decision: T. rex had lips. In the debate over dinosaurs’ “oral margin,” one of the country’s top paleoartists has taken sides. Mr. Keillor’s job is to create “flesh models” of dinosaurs and other prehistoric animals based on fossil evidence—giving creatures that died millions of years ago a face, a story and sometimes lips.

Using traditional mediums like clay and resin, as well as CT scanning and 3-D printing, he is at the forefront of incorporating digital art and technology into paleontology.

Mr. Keillor works at the University of Chicago Fossil Lab under celebrity paleontologist Paul Sereno. His work, found in museum collections around the world, is often the public’s first look at a newly discovered species, as with the pebbly-faced predator Rugops primus, which was unveiled in 2004. “A plain fossil doesn’t look like a heck of a lot to the average person,” Mr. Keillor says.

Instead of studying science, he cut his teeth working in a dental laboratory, doing special-effects makeup and studying wig making at Chicago’s Lyric Opera. As a child, he “would try to make little puppets of the alien from ‘Alien,’ ” he says. He dropped out of college to work on low-budget horror movies, commercials and stage productions.

His skill set was well-suited to Dr. Sereno’s team. After another paleoartist struggled with the hair of a “7,000-year-old beautiful woman,” Dr. Sereno says, he turned her over to Mr. Keillor. “When you see it in the ground in the field, you need to have the mind and eye of an artist,” he says. “Paleontology is about envisioning things and bringing them back to life.”

On a recent Thursday, the soft-spoken Mr. Keillor, 42 years old, was painting orange silicone over pieces of a 95-million-year-old rib, the last of about 100 Spinosaurus bones he was reproducing for the University of Chicago before it repatriated the originals back to Morocco.

Croc's grandpappy found in the Carolinas

Meet the 'Carolina Butcher,' a Pre-Dino Predator
Carnufex carolinensis roamed the earth roughly 231 million years ago, researchers say.
The Carnufex carolinensis, illustrated in this artist's rendering, is believed to have measured 9 feet long.

Herbivores, meet your worst nightmare.

Scientists on Thursday announced the discovery of a fearsome crocodilian ancestor: A 9-foot-long fanged beast that roamed prehistoric North Carolina 231 million years ago.

Stomping about on hind legs like the long-lost miracle love child of supervillains Killer Croc and the Lizard, researchers believe Carnufex carolinensis – meaning "Carolina Butcher" – feasted on armored reptiles, early mammal relatives and other small prey that made their home in the Tar Heel State, which researchers say was then just breaking apart from the supercontinent Pangea.

“The discovery of Carnufex, one of the world’s earliest and largest crocodylomorphs, adds new information to the push and pull of top terrestrial predators across Pangea,” Lindsay Zanno, an assistant research professor in the biology department at North Carolina State University, said in a statement.

The skull, spine and upper forelimb of the reptilian beast were uncovered in the Pekin geologic formation in North Carolina's Chatham County, where ancient sediment has churned up other prehistoric remains.

"Fossils from this time period are extremely important to scientists because they record the earliest appearance of crocodylomorphs and theropod dinosaurs, two groups that first evolved in the Triassic Period, yet managed to survive to the present day in the form of crocodiles and birds," Zanno said.

Already, scientists believed that cousins of the ancient crocodile ranked among the top predators in the Southern Hemisphere, hunting alongside theropod dinosaurs – a dynamic that created a “predator pileup” and led to the extinction of the crocodile relatives.

Hidden in a museum, new species of Ichthyosaur discovered.

New species of ichthyosaur found in museum archive

A fossil spent 30 years stored away in a South Yorkshire museum, believed to be a plaster replica and forgotten, until it caught the eye of a young paleontologist working in the museum’s collections, who has now identified it as a new species of prehistoric marine reptile. 

Dean Lomax, 25, determined the fossil to be 189 million years old, the remains of a species of ichthyosaurus, a carnivorous seagoing reptile shaped like a dolphin.

Lomax published his findings in the latest issue of the Journal of Vertebrate Paleontology.

So well preserved was this Jurassic mummy at the Doncaster Museum and Art Gallery, that Lomax was able to see the inside of its stomach, where they found the hook shaped remains of a squid, the entree of its last meal.

Lomax worked on the project alongside Judy Massare, from the State University of New York, comparing their specimen’s skeleton to those of nearly 1,000 different ichthyosaur specimens kept in museums throughout the US and Europe.

Several features on his specimen’s fin bones set the animal apart from its Jurassic cousins. Ichthyosaur remains actually appear quite often in Great Britain, where it filled the seas in sufficient numbers in the days when dinosaurs roamed the Earth. They became extinct some time in the Late Cretaceous period 70 million years ago, before the extinction of the last dinosaurs. Mary Anning, a seashell collector and amateur fossil hunter, found the first one back in 1811, and Lomax’s specimen is named Ichtyhosaur annigae in her honor.

How Lomax’s specimen got mistaken for a copy is unclear, as it was particular specimen was found on the coast of Dorset back in the early 1980s and presented to the museum.

Dino burns like fossil fuel.

Clive Palmer's dinosaur Jeff destroyed by fire at Palmer Coolum Resort

Fire has destroyed a 10-metre model Tyrannosaurus rex, nicknamed Jeff, that was standing at Clive Palmer's resort on Queensland's Sunshine Coast.

Firefighters were called to the blaze at the Coolum resort about 1:30am to find Jeff already well alight.

Police had been investigating whether the fire was started deliberately, but Mr Palmer told the ABC he did not believe arson was involved in Jeff's demise.

"Apparently he's had an electrical fault and burnt down," he said.

"There was a storm through the morning and all I know is there was an electrical fault and he caught fire and that was the end of him."

Mr Palmer said he was still deciding whether to bring in a replacement once what remained of Jeff was dismantled.

"Jeff's brother is waiting in the dinosaur park to be liberated to take his place," the Federal MP said.
"Question is whether we bring him out or whether we leave him where he is - he's very happy with the other dinosaurs.

"Certainly the next birth we have of a dinosaur, we will name after Jeff."
Queensland Fire and Emergency Service Superintendant Russell Thompson said Jeff's rubber and fiberglass coating burnt "very, very quickly".

"Very unusual call this one - we had a dinosaur on fire. I've had everything else but this is the first time I've had a dinosaur on fire," he said.

"There was only a small section of the tail left that was unburnt once the first appliance arrived.
"They had that fire out within a few minutes."

Finally, recognition!

Sir Richard Owen: The man who invented the dinosaur

The Victorian scientist who coined the word "dinosaur" has been honoured with a plaque at the school he attended as a child. But who was Sir Richard Owen?

Dinosaur fossils have been the subject of mystery, superstition and scholarly wonder for millennia, but the prehistoric reptiles did not receive their famous name until 1842.

Marvelling at the specimens being uncovered in southern England at the time, a young Owen recognised that the remains shared a number of distinctive features.

They were "terrible lizards", he said. A diverse family of awesome animals that deserved their own distinct taxonomic group - which he named Dinosauria.

The palaeontologist, who rose from a poor background in Lancashire to become something close to what we might consider a celebrity scientist today, went on to establish London's Natural History Museum in 1881.

There, the latest fascinating dinosaur fossils became famous around the globe, and the terracotta-walled institution remains at the forefront of research today.

Private ownership of fossils? Yay or nay?

Dinosaurs for sale: How fossil business impacts science

Commercial sellers offer scientists access to unique specimens, but at a cost

In 2009, commercial fossil hunters in Montana excavated what was, unbeknownst to them, the jaws of an important new species of dinosaur.

Scientists weren't informed, and the fossil was sold to a private collector.

Fortunately, the story doesn't end there, as it sometimes does.

'It's wrong for people to assume they can get something for free.'- Peter Larson, Black Hills Institute of Geological Research

In the fall of 2010, the private collector heard that paleontologist David Evans of the Royal Ontario Museum in Toronto would be visiting his town of Fort Peck, Mont. He wanted to know more about the fossil he had purchased, so he showed it to Evans.

"I was blown away," Evans recalled. "I instantly knew it was a new species of raptor."

"It was a unique find that is scientifically very important," added Evans, who co-authored a paper describing the new raptor in 2013.

The jaws turned out to belong to the only raptor from its time period ever found in North America. The turkey-sized meat-eater named Acheroraptor temertyorum would help paint a more vivid picture of the diverse ecosystem where Tyrannosaurus rex stalked Triceratops 66 million years ago.

Acheroraptor also revealed a surprise — it was a close relative of dinosaurs in Asia, suggesting that dinosaurs were migrating between continents.

But no one knew any of that until Evans, the  ROM's curator of vertebrate paleontology and an associate professor at the University of Toronto, talked the collector into selling his treasure to the ROM. It became part of the ROM's collection in 2011. The museum doesn't disclose the prices it pays in order to minimize their effect on the market, but Evans said it was reasonable and affordable.

Bringing the fossil into a museum was the only way it could be studied and be recognized as a new species with its own scientific name. That's because science needs to be repeatable by other scientists, Evans said, and that's possible only when they have unrestricted public access through an institution such as a museum.

"If we had not bought it," he added, "it would have continued to be in the hands of a private collector and off-limits to science."
Acheroraptor illustration

The story of Acheroraptor illustrates how buying fossils from commercial collectors can provide scientists and the public with access to extraordinary dinosaur specimens they couldn't otherwise study. But it also shows how easily the commercial trade can inadvertently keep important specimens out of scientists' reach.

That is, the bustling dinosaur business has a profound influence on the science of paleontology – something that paleontologists struggle with.

Canadian museums often buy dinosaur fossils

Dinosaurs are a huge public draw, but for many Canadian museums, buying dinosaurs is the only way to get them.

Laws enacted since the late 1970s in the main provinces where dinosaur fossils are found — Alberta and Saskatchewan — specify that dinosaur fossils are owned by the Crown. Regulations effectively ban them from being removed from the province.
Acheroraptor

If the Royal Ontario Museum had not bought the Acheroraptor fossil, it would have remained off-limits to science, says curator and paleontologist David Evans. (Royal Ontario Museum)

Paleontologists say the laws do a good job of safeguarding fossils for science. But they mean museums like the ROM, located in Ontario where no dinosaur fossils have been found, can't grow its collection except by buying fossils from outside Canada, mainly from the U.S.

"Every major museum in Canada buys fossils and it's been a common practice for a century," Evans said.

That said, museums far prefer to collect fossils themselves than buy them — partly because many have trouble affording them, and partly because commercial specimens are often missing important scientific data about their origins.

Dinosaurs on Mars!

 

Mars Dinosaur? It's Just Another Curio From Curiosity Rover

If you scan through the thousands of pictures that NASA's Curiosity rover has sent back from Mars, you'll find a lot of interesting rock formations. Some of them, including a formation that looks like a toothy dinosaur skull, wind up on Scott Waring's UFO Sightings Daily.

The "Ancient Dinosaur Skull" is the latest offering, but the picture was actually taken a long time ago — back on Sol 297 in June 2013, when Curiosity was rolling through an area known as Glenelg. Scientists say the site was a stream bed in ancient times, as evidenced by the rounded pebbles strewn across the landscape.

Some of those pebbles ended up stuck in the crevices of a wind-sculpted rock, and all this led Waring to call attention to the dinosaurian appearance: "Look closely and you will see there is a nostril area, lower jaw area and jaw hinge area as well," he writes. "There are also teeth. A crap load of teeth and evenly spaced and white as all get out. It's the details that we have to focus on. It leads us to the truth."

Yes, the truth is out there — and the truth is that this is the latest example of pareidolia, the human tendency to pick out seemingly meaningful patterns even in randomly arranged phenomena. The Face on Mars is a good example of that, as are the Mermaid on Mars, the Mars Rat, the Mars Iguana, the Penis on Mars, the Rover Rotini and other Red Planet anomalies.

What is it about Mars that sparks so many strange sightings? Now that's a mystery worth investigating.

Does DNA remember?

Can evolution run BACKWARDS? Birds found to regrow bone previously discarded by dinosaurs 230 million years ago

• Scientists have found that birds regrew a bone known as the 'pisiform'
• It disappeared from the biology of two-legged dinosaurs when they no longer needed strong wrists
• However when dinosaurs evolved into birds the bone reappeared
• The new bone is known as the ulnare and is in the same position
• It suggests the effects of evolution can be reversible

In 1890 Belgian palaeontologist Louis Dollo postulated that evolution could not run backwards - something widely accepted by the scientific community.

But now a study has claimed that the changes induced by evolution can be reversible, meaning certain animals can return to an earlier biological trait.

The remarkable discovery was made by finding birds had regrown a bone previously discarded by dinosaurs millions of years ago.

They found that 230 million years ago, two-legged dinosaurs no longer required the strong wrists of their four-legged brethren, and thus they became weak.
The number of bones in wrists shrank from 11 to three, with one in particular of interest to disappear being the pisiform.

But according to research by Dr Vargas, the bone reappeared when dinosaurs evolved into birds and took flight.

The new bone, called the ulnare, appears in the same place as the pisiform once did.
The pisiform allowed bird wings to remain rigid on the upstroke. The study found it disappeared in bird-like dinosaurs, but modern birds later evolved to once again use this tiny bone.
'This idea that a bone can disappear and reappear in evolution has been resisted a lot in evolutionary biology,' Dr Vargas previously told Stephanie Pappas at LiveScience.

Scientists don't know how these bones disappeared, though. Professor Vargas said part of the problem is that palaeontologists look at fossils, while biologists focus on embryos.

But his team brought the research together by looking at fossils as well as studying bird anatomy.
The team also traced certain proteins in 3D embryonic skeletons that were linked to the creation of collagen, which makes up connective tissue.
