Tetrapodophis (meaning "four-footed snake" in Greek) is an extinct genus of snake from the Early Cretaceous of Brazil. It is one of the oldest snakes and the only known snake with four legs. The type species, Tetrapodophis amplectus, was named in 2015 on the basis of a complete skeleton (BMMS BK 2-2) preserved on a limestone slab in the Bürgermeister Müller Museum in Solnhofen, Germany, which was labeled as "unknown fossil" until its importance was recognized by paleontologist David Martill. The specimen was later determined to come from the Early Cretaceous Crato Formation in Ceará, Brazil.
