This is a nearly complete skull of Notochoerus euilus found at East Turkana, with dentition (P3-M3). Notochoerus euilus is common in middle to late Pliocene fossil deposits of the Koobi Fora Formation where the earliest occurrence is from within the Moiti Tuff dated to 3.89 myr. Notochoerus euilus gave rise to the truly massive Notochoerus scotti, which occurs in the Late Pliocene and Early Pleistocene. Both species became extinct just less than 2 million years ago.
Notochoerus euilus was a large pig, standing approximately 120 cms at the shoulder. Isotope analyses of its dental enamel suggest that the majority of the specimens were grazing on tropical grasses, although some individuals were consuming some non-grass plants. Third molar height and length appear to increase with time. Molar pillars are widely separated to the base and taper steeply.
