Adamanterpeton is a genus of edopoid temnospondyl within the family Cochleosauridae. Two specimens were discovered in the fossil-rich locality of Linton, Ohio. The type species A. ohioensis was named in 1998. Adamanterpeton is rare in the Linton vertebrate assemblage, with other amphibians like Sauropleura, Ophiderpeton, and Colosteus being more common. Unlike other Linton vertebrates, Adamanterpeton may have been adapted to a terrestrial lifestyle.
