Overview:

A study in Nature finds a near-complete skeleton of an early reptile from the Middle Jurassic period of Scotland.

About Bellairsia gracilis:

  • The skeleton is of Bellairsia gracilis, a primitive squamate.
  • Squamates are a group of reptiles that includes more than 10,000 living species descended from a shared common ancestor that lived 240 MYA.
  • The fossil may improve our understanding of the anatomical transformations that led to the establishment of the body plan of reptiles such as modern lizards.
  • If the anatomical interpretation is correct, then primitive squamates survived for tens of millions of years after the first lizards and snakes evolved and lived alongside them.
