200 million years old in the jaw is revealed as new species

Scientists discovered a new species in the Pterosaur – a flying reptile that heals dinosaurs over 200 million years ago.

The bone of the jaw of the ancient reptile was unable to change in Arizona in 2011, but modern scan techniques now reveal details that are new to science.

The research team, headed by Scientists at the National Museum of Smithsonian in Natural History in Washington DC, calling the Eotephradacyaclus McIntiracy creature

It is a volcanic ash reference that helps preserve its bones in an ancient river.

Details of discovery Published by Journal Handles of National Academy of Science.

In about 209 million years old, it is now believed to be the first pterosaur found in North America.

“The bones of Triassic Peterosaars are small, thin, and always hollow, so they will be destroyed before they fail,” Dr. Kligman explained.

The site of this discovery is a fossil bed in a desert scene of ancient rock in petrified national park.

More than 200 million years ago, this area was a river, and layers of sediment gradually trapped and preserved bones, stacks and other evidence of life.

The stream runs in the central region what is above Pangea, formed from the whole land of the earth.

The jaw of the pterosaur is just a part of a collection of fossils found at the same site, including bones, teeth, fish scales and even fossilized poo (also known as coprolites).

Dr. Kligman said: “Our ability to recognize the bones of the pterosaur in (these ancient) river deposits that may have other rocks around the world that can also preserve the bones of the pterosaur.”

The study of pterosaur teeth also gives hints about what seagull-sided eoser edreed reptile eats.

“They have an unusual level of wearing their tips,” Dr. Kligman explained. suggests that this pterosaur is to feed something with parts of the body. ”

The most likely victim, he told BBC News, was the first fish covered with an armor of scales.

Scientists say that the discovery site stores a “snapshot” to an ecosystem of the animals present domestic animals known today, including frogs and turtles.

This fossil bed, said Dr Kligman, saved evolution of an evolution “shift” 200 million years ago.

“We see groups lasting late living with older animals (left) make this triassic.

“Fossil’s beds like this can establish all these animals actually live together.”
