Newswise — Findings, recently published in the journal Science Advances, show that snakes did not lose their limbs in order to live in the sea, as has been previously suggested. The research led by scientists at the University of Edinburgh’s School of GeoSciences involves the analysis of a 90-year old reptilian fossil of Dinilysia patagonica, a 2-meter long reptile. Computed tomography (CT) scans of the bony inner ear of Dinilysia patagonica reveals how this ancestor to modern snakes became adept at burrowing.
