TL;DR Summary
Researchers have discovered the world's oldest known fossilized skin, dating back around 289 million years, from a species of reptile that predates dinosaurs. The skin fragment, found in an Oklahoma limestone cave, is at least 130 million years older than the previous oldest known skin fossil. The sample, resembling crocodile skin with hinged regions similar to snakes and worm lizards, provides insight into the evolution of terrestrial animals and the importance of the epidermis as a barrier between internal body processes and the external environment. The study was published in the journal Current Biology.
