Found fossil proto-turtle, which explains the development of tortoiseshell


Near the New Mexico found fragments of skeleton reptiles, age about 210 million years old. This finding is important because it suggests a new perspective on the process of formation at the earliest turtles protective shell.

According to the American paleontologist, fossil turtle, dubbed Chinlechelys tenertesta, has the smallest shell in the world. The width of the shell plates of one millimeter, while itself turtle reached to 30 centimeters in length.

According to study author, paleontologist Walter Joyce Museum of Natural History and Science in New Mexico (Walter Joyce, Peabody Museum of Natural History in New Haven, Connecticut), found a turtle can be called proto-turtle with the thinnest shell, found today .

This means that the detected species of turtles lived on Earth during the Triassic period of the Mesozoic era. That is, before the Jurassic period there were familiar with this wide turtle shell. The dorsal fin reptiles do not fully connected to the shell, as is to be found in the later fossils and in modern turtles.

Joyce says it is not known exactly why the shells of turtles appeared. Solid shield on his back could offer greater protection reptiles. See, for this reason, thin protective plate in the process of evolution blended with each other and with the edges of the skeleton, forming a solid protective shell, known to us by modern turtles.
