Researchers have found fossilized skin of one of the world’s oldest reptiles. A new study has shown that reptiles of that species lived before the dinosaurs roamed the earth.

According to the report of CNN, the fossil fragment of the skin of this reptile was found in a limestone cave in Oklahoma, USA. It is at least 13 million years older than the oldest skin fossils ever found.

Researchers at the University of Toronto Mississauga found this skin fragment. It looks like crocodile skin. This information is known according to a press release published last Thursday.

One of the authors of the paper, Ethan Mooney, a graduate student in the Department of Physiology at the University of Toronto, said, ‘It is an extraordinary opportunity to see such rare fossils over such a long period of time. Such a discovery really enriches our thinking and knowledge about such ancient animals.’

“Finding fossilized skin is very rare, even though it is the largest organ in the body,” said study co-author Robert Reisz, professor of biology and paleontologist at the University of Toronto Mississauga. But the skin decomposes easily after an animal dies. The specimen is preserved in a limestone cave. The condition of the cave was very unusual.’

About the caves where the fossils were found, the researchers said that due to the characteristics of the alluvium, the animals buried in the caves slowly decomposed. The oil flowing there helped preserve the skin by interacting with the hydrocarbons. In addition, the researchers believe that the cave was probably without oxygen.
