Fossils have been found from the Ruprechtice horizon of the Intrasudetic Basin of Bohemia in the Czech Republic, as well as the Saar-Nahe Basin of southwestern Germany. Cheliderpeton had a 16 cm skull, and reached about 65 cm in length.

The preoccupied generic name, referring to the trunk armour of turtles, was first changed into Chelydosaurus in 1885 and finally into Cheliderpeton in 1887. A second species named C. latirostre was described in 1993 by J. A. Boy from Germany, after having been assigned to Archegosaurus. It differs from the type in having a less extensive preorbital region of the skull, a wider cheek region, and a snout tip that is less round and has lateral projections. Currently the two species are the only ones known to belong to Cheliderpeton, although there have been more assigned in the past that are now considered to be synonymous with the known species. "Actinodon germanicus", described by O. Kuhn in 1939 on the basis of a specimen found from the Czech Republic, It is now known to be an unusually large individual of C. vranyi, probably in a late stage of ontogenic development.
