Les tortues du Pliocène d'Ahl al Oughlam (Casablanca, Maroc) et de localités mio-pliocènes avoisinantes

Turtles from the Pliocene of Ahl al Oughlam (Casablanca, Morocco) and nearby Mio-Pliocene localities. The Late Pliocene locality Ahl al Oughlam (Casablanca, Morocco) yielded a fauna of cryptodiran testudinoid turtles, all of them related to extant African forms. Two terrestrial and one freshwater species are recognized. First, a new small species of the palaearctic genus Testudo Linnaeus, 1758, T. oughlamensis n. sp., is abundantly represented and is closely related to T. kenitrensis Gmira, 1993, from the Middle Pleistocene of Kenitra, Morocco. It is compared to other new remains of Testudo from nearby localities of similar age, including Dehar Mouak and Ar Rehamna. Together with T. kenitrensis, it constitutes a new clade within Testudo, providing a minimum age for the divergence between this clade and T. graeca Linnaeus, 1758 from Morocco. Secondly, the giant ?Centrochelys marocana n. sp., is probably related to the extant C. sulcata (Miller, 1779). Its description gives the opportunity to exami...
