The discovery of a new prehistoric lizard shifts the timeline of when reptiles evolved! The remains were found embedded in a rock in storage since the 1950's at the National History Museum in London.Cryptovaranoides microlanius dates back about 202 million years, placing it firmly in the Triassic period. It is also 35 million years earlier than previously recorded reptilian life!

But despite the lizard's small stature, its sharp teeth would have delivered a menacing bite, which inspired the paleontologists to name it Cryptovaranoides microlanius; the species name means "small butcher," while the genus means "hidden" and "lizardlike," a nod to the decades it spent languishing unnoticed in NHM storage. When C. microlanius was alive, it likely preyed on arthropods and small vertebrates on the limestone-rich islands that once surrounded what is now Bristol, according to the study.
