Catopithecus Browni Simons, 1989

Catarrhine genus from the late Eocene and early Oligocene of North Africa, belonging to the family Propliopithecidae; monotypic; known from skulls, jaws, and some limb bones. Phylogenetic relationships uncertain except that it is an anthropoid; it has some adapid traits, which have generated a debate regarding anthropoid origins, previously considered to be from the omomyoids. Small orbits indicate diurnal activity. Estimated body mass around 1 kg. Dental formula: 2.1.2.3; anterior dentition is anthropoidlike, while cheek teeth are a mosaic of anthropoid and adapid traits; dental morphology suggests a mixture of frugivory and insectivory as the diet. Postcranial remains suggest arboreal quadrupedalism with little leaping or clinging ability.
