Bairdemys is an extinct genus of side-necked turtles in the family Podocnemididae. The genus existed from the Late Oligocene to Late Miocene and its fossils have been found in South Carolina, Puerto Rico, Panama and Venezuela. The genus was described in 2002 by Gaffney & Wood and the type species is B. hartsteini.
Description
The first species in the genus described was B. venezuelensis as Podocnemis venezuelensis by Wood and Díaz de Gamero in 1971.[8]
