  Genus Najash
Najash is a early genus of snake that lived during the late Cretaceous period, about 90 million years ago. Its fossils were found in a terrestrial deposit in the Rio Negro province of Patagonia in Argentina.

The fact that it was found in a terrestrial deposit, is often cited as evidence against Edward D. Cope's hypothesis that snakes share a common origin with Mosasaurs (although a marine origin for snakes seems suggested by other early snakes that have been discovered: Eupodophis, Haasiophis and Pachyrhachis)

Najash was about 5 feet (1.5 meters) long, and is believed to have been a burrowing animal. It had two hind legs that seem to be adapted for burrowing, and also retained its pelvic bones.
