Cochilius is an extinct genus of interatheriid notoungulate that lived between the Late Oligocene and the lower Miocene in what is now Argentina.
==Description== The skull and skeleton show features also found in other similar contemporary or slightly later animals, such as Interatherium and Protypotherium. In the general proportions of the skull Cochilius was similar to Interatherium, but in some features it was closer to Protypotherium, for example, in the large development of the snout and the median position of the orbits. The epitympanic sinus was slightly spongy. The forelimbs resembled those of Interatherium, and were more puny than those of Protypotherium. The metacarpal bones were longer and thinner than those of Interatherium. The incisors were short and strong, while the molars were low-crowned (brachydont) teeth.
