New fossils of an ancient legged snake called Najash rionegrina offer new information on the evolution of snakes
An article published in the journal “Science Advances” reports the study of new fossils of a snake belonging to the species Najash rionegrina, which lived in the Cretaceous period, between 90 and 100 million years, in today’s Patagonia, Argentina. A team of researchers led by Fernando Garberoglio of the Fundación Azara at Universidad Maimónides in Buenos Aires, Argentina, subjected various fossils belonging to this species, which had well-developed limbs, to a high-resolution CT scan to obtain new information on the evolution of snakes.
