North America’s oldest known Pterosaurs, which was discovered in Arizona, say researchers, say researchers

For the paleontologist Ben Kligman, the question was: Is this fragile jawbone a pterosaurs or not?

Other researchers also had questions about the fossil, which were excavated by others for decades of archaeological excavation in a remote bone bed in the National Park reinforcement forest in Arizona. Some thought that the bone could have been a mammal, Kligman told CBS News.

Now her new research offers an insight into the oldest known flying reptile of North America, which Kligman and other paleontologists say that it was the size of a “small seagull”.

The newspaper, which was published by Smithsonian, published on Monday in the Proceedings of the National Academy of Sciences Journal on Monday, describes the new discovery of the Pterosaur fossil and provides an insight into the late triad period.

Kligman remembers that he looked at the jawbone under a microscope of the Smithsonian – where he is a postdoctoral of Peter Buck and where the fossil was sent – and through his “Rolodex” by Triassic jaw anatomy, over which species could be a similar jaw. He wanted to solve the secret where the delicate jawbone belonged from.

Due to the process of elimination and thinking about the characteristics that Pterosaurs have that no other animal has it, Kligman said that he and other researchers could come to the conclusion: “Oh yes, this is definitely a Pterosaurs – so this is a very important discovery.”

The team called the Pterosaurs the Eotephradactylus Mcintireae, which means “goddess of the ash -winged dawn”. The name name refers to his explorer Suzanne Mcintire, who voluntarily reports in the Fossilab of Smithsonian for 18 years.

Mcintire discovered the Pterosaur fossil, which was brought from the petrol forest to the museum together with 1,200 other individual fossils, including bones, teeth, fish scales and coprolith or fossilized excrement.

Volunteers clean every fossil, flag that are of interest and carry out other tasks for fossil preservation. Mcintire discovered the jawbone and noticed that the teeth were still in the bone, which made identification easier.

The winged reptile – a narrow cousin of dinosaurs and the first animals after insects to develop driven flight – would have been small enough to comfortably sit in a person’s shoulder.

“It could have been on her shoulder like a little seagull,” said Kligman about the species.

The researchers were able to date the fossil from fossil 209.2 million years ago – an unusually accurate date, said Kligman, because the fossil level was found. The finding helps to close a gap in the fossil stock that lies before the end of the end triad, he said. There are very few pterosaur fossils, said Kligman. After their extinction, their fragile bones have received poorly, so pterosaur fossils are often incomplete. They also did not live near places where fossils form.

“It helps us understand what a pterosaurs were and how they became what they would be,” said Kligman.

Together with the Pterosaurs, other results described in the study, including one of the oldest turtle fossils in the world, huge amphibians and armored crocodile understanding that lived in addition to evolutionary advancements such as frogs, turtles and pterosaurs.
