As for the world of excavations, Ben Klijman, the question was: Is this the brittle jaw bone or not?
Other researchers also had questions about Al -Ahfour Forest National Park fossilized In Arizona. Clegman told CBS News that the bone could have been mammals.
Now, their new research presents an insight into the oldest flying reptiles known in North America, which Kligman and other excavation scientists say the size of “small birds”.
The paper led by Smithsonian, Publish Monday In the facts of the National Academy of Sciences Journal, the details of the new fossil discovery of innate women, along with many others, providing an insight into the late periodic period.
Kligman recalls looking at the jaw bone under a microscope in Smithsonian – where it is a Petter Pak Fellow after doctorate And where the fossils were sent – and ran through “Rolodex” from the autopsy of the triangular jaw, thinking about the species that could have a similar jaw. He wanted to solve the mystery of the place to which the delicate jaw bone belongs.
Through the process of eliminating, thinking about the features that the crawles that no other animal had, Clegman said that he and other researchers were able to conclude that “Oh yes, this is definitely a Petrosor – therefore, this is a very important discovery.”
Ben Klijman, post -doctoral Peter Pak and the world of excavation at the Smithsonian National Museum of Natural History, was quarantined in the bitter forestry garden in Arizona in 2025.
The team called the EostharadaCtylus Mcintireae, which means “the dawn deities of ash”. The name of the species indicates its discovery, Susan McCainer, who volunteered in Smithsonian Hole For 18 years.
The creeping Mcintire Mcintire, which was brought to the museum from Forest Forest, discovered alongside 1,200 other individual holes, including bones, teeth, fish standards, stool or stools.
Volunteers clean all fossils, their knowledge of attention and the performance of other excavations. Mcintire discovered the jaw bone and note that the teeth are still in the bone, which makes it easy to determine.

Winked reptiles – a cousin close to dinosaurs and First animals After the insects to develop a powered journey – it was small enough to sit comfortably on the person’s shoulder.
“He could have sitted on your shoulder, like small seagulls,” Kligman said of this type.
Clegman said that the researchers were able to determine the date of return to 209.2 million years – an unusually accurate date, due to the level of volcanic ash as the fossils were found. He said that the result helps fill a gap in the fossil registry that precedes the final extinction of the traiti. Kligman said that very few petrosal fossils exist. After its extinction, their fragile bones are badly preserved, so boating fossils are often incomplete. They did not do Nest To the places where fossils tend to form.

“This helps us to understand what the wedding is and how they will become what they will become,” said Kligman.
Along with the creeping, the study also detailed to other results, including one of the oldest turtle fossils in the world, giant amphibians and armored crocodile relatives, who lived alongside evolutionary events such as frogs, turtles and petroics.
