Teyumbaita (meaning "lizard (Teyu´) and parrot (Mbaita´)" in the Brazilian aborigine Tupi-Guaraní language) is an extinct genus of hyperodapedontine rhynchosaur from the Upper Triassic (early Norian age) epoch of Paleorrota, Rio Grande do Sul, southern Brazil. Its fossils, two nearly complete skulls and a partial skull were discovered in the lower part of the Caturrita Formation and was first assigned to a species of Scaphonyx (now considered to be a nomen dubium), Scaphonyx sulcognathus. This species was reassigned to its own genus by Felipe Chinaglia Montefeltro, Max Cardoso Langer and Cesar Leandro Schultz in 2010 and the type species is Teyumbaita sulcognathus.[1] Fossil material of a second, yet-unnamed species, is known from the Hoyada del Cerro Las Lajas site of the Ischigualasto Formation (Argentina).[2]
