==Description==

This animal is mostly known from several cranial remains, including an almost complete skull, teeth and mandibles. Comparison with some of its better known relatives allows to portray a small animal, somewhat similar with [[rodent]]s, and weighing less than two kilograms. The snout was higher than in ''[[Notopithecus]]'', with a longer rostrum ; the mandible was short and thick, with a particularly massive, short and broad [[mandibular symphysis]]. The tympanic bullae were modestly sized.

''Archaeopithecus'' had conical incisors, similar to its canines, and triangular-shaped upper premolars, devoid of hypocone. The premolars and molars had a strong parastyle and a paracone fold. Unlike other Eocene notoungulates such as ''Notopithecus'' and ''[[Oldfieldthomasia]]'', which had low-crowned teeth, ''Archaeopithecus'' had a near-hypsodont (high-crowned) dentition, with short diastemas between the anterior teeth. The teeth of ''Archaeopithecus'' show an important occlusal variability during growth, associated with a variations caused by wear in the size of the teeth : with the progress of dental wear, the upper molars became wider, while the lower molars became broad and short.
