SmithsonianScientists have discovered a new species of Pterosaur – a flight reptiles that were above dinosaurs over 200 million years ago.
The jaw of ancient reptiles was detected in Erizona in 2011, but modern scanning techniques have now shown details that it is of a new species for science.
The research team led by scientists of Smithsonian National Museum of Natural History at Washington DC has named Zoological Eutfradectylus McIetere, which means “Ash-Winged Don Devi”.
It is a reference to the ash of volcanoes that helped preserve its bones in an ancient river.

At the age of about 209 million years, it is now believed that it is the first perosaur found in North America.
Dr. Cligmanman said, “The bones of Trichic Petosaurus are small, thin and often hollow, so they are destroyed before fossils.”
The site of this discovery has a fossil bed in a desert landscape of the ancient rock in the site Petridified Forest National Park.
More than 200 million years ago, this place was a river baby, and the layers of sediment gradually got stuck and the bones, scales and other evidence of life were preserved.
The river lasted through the central region, which was the supercontinent of Panzia, which was formed from all the landmas on the Earth.
The pterosaur jaw is just a part of the collection of fossils found on the same site, including bones, teeth, fish scales and even fossils (also known as corolites).
Dr. Climman said: “Our ability to recognize our ability [these ancient] River deposits suggest that other similar accumulation can be accumulated from trichic rocks worldwide that can also preserve the bones of the perosaur. ,
Ben CligmanBy studying the teeth of Pterosaur, it was also provided a clue of what the reptiles with seagel shaped wings would have eaten.
Dr. Cligmanman said, “They have unusually wearing unusually high on their suggestions.” Suggesting that this pterosaur was feeding on something with hard organs of the body. ,
Most likely hunting, he told BBC News, primitive fish that were covered in a armor of Boney’s scales.
Scientists say that the site of the discovery has preserved the “snapshot” of an ecosystem, where groups of animals that are now extinct, including huge amphibians and ancient armored crocodile relatives, lived with animals that we could recognize today, including frogs and turtles.
Dr. Cligmanian said that this fossil bed, 200 million years ago, preserved evidence of a evolutionary “transition”.
“We look at groups that later live with old animals [didn’t] Last it with tricyc.
“Fossil beds like these enable us to establish that all these animals used to live together.”
