"Other turtles in the study area are the pond or swamp dwelling taxa Hoplochelys (Kinosternidae, mud turtles), Judithemys (Sinemydidae, extinct group) and Compsemys, a small snapping turtle-like animal."
― Saurian: A Field Guide to Hell Creek
Compsemys was an extinct genus of paracryptodiran testudinatans, closely related to the baenids, from the Late Cretaceous and Paleocene of North America. It was found in many fossil formations, including the Hell Creek Formation. This turtle is peculiar, due to having a shell covered in raised flat tubercles, not seen in any other testudinatan. It also possesses a skull that resembles the ones of modern alligator turtles, at one point being considered as a close relative of them, which indicates this 30 centimeter long testudinatan was a vicious predator of small aquatic creatures.
