Labidosaurus hamatus

Labidosaurus (from , 'forceps' and , 'lizard') is an extinct genus of captorhinid tetrapods from the Permian period of North America. Fossils have been discovered in Texas.

It was heavily built, resembling a lizard with a large head, and measuring about long. Like most captorhinids, it was probably quadrupedal. Unlike many other captorhinids it had a single row of sharp, conical teeth in its jaws, and its dietary habits are assumed to have been omnivorous.
