WebYou are collecting fossils in Kenya’s Turkana Basin when youcome across a nearly complete fossil primate skull and jaw. You know that the deposits are Plio-Pleistocene in age and you notethat the skull and jaw possess the following features: 2-1-2-3dental formula, bilophodont molar pattern, large canines, and along snout. WebO a Y-5 molar pattern and sinodonty. large canines and no diastema. O sharp, high crests on the teeth.

Molar (tooth) - Wikipedia
WebThe bilophodont tooth pattern is found in cercopithecoid monkeys in the three upper molars as well as the first and second lower molars. In the mandibular molar, an elongated heel at the back of the tooth carrying a fifth cusp, the hypoconulid is added on to the typical bilophodont tooth. WebBy available fossil evidence, the earliest appearanceof our suborder, Anthropoidea, is in Middle Eocene deposits of North Africa (Algeripithecus, 50- 46 m.y.) and China(Eosimias, 45 m.y.). But these earliest traces are known from only a fewteeth and jaws without the skull. east new haven ct
