Palaeochersis is an extinct genus of rhaptochelydian turtle from the Los Colorados Formation of Argentina. It is known from one species, Palaeochersis talampayensis.

Discovery and naming

Palaeochersis talampayensis is known from three specimens: PULR 68 (holotype), a skull and postcranium. PULR 69, a right tarsus and pes, and PULR 72, a skull. The three specimens were each collected together in 1992 within the Los Colorados Formation, Argentina.

Palaeochersis talampayensis was then named and described by Rougier, de la Fuente & Arcucci (1995).

Classification

Palaeochersis was part of the Australochelyidae, being the sister taxon to Australochelys.
