The Ancestor of All Scaled Reptiles

The Ancestor of All Scaled Reptiles 

THIS ARTICLE tells us of a very well preserved, but tiny (32mm), fossil found in north west Argentina in 231 million year old (Late Triassic) sediments. It is described as the most primitive scaled reptile yet found.

It is a Lepidosaur - a group which contains lizards and snakes - the most diverse group of terrestrial vertebrates presently alive. But very little is known of their early origins. I has been named Taytalura alcoberi.

The enormous reptiles of the period are well known. In contrast, the little ones are almost unknown. It is hoped that this specimen will lead to the areas of ignorance being diminished.

If you have access you can read the original paper HERE.
