ANT 350 Lecture Notes - Lecture 21: Lothagam, Glossary Of Mammalian Dental Topography, Mental Foramen
Document Summary
Compare the teeth and palates of a. afarensis and the chimpanzee. Incisors: similarly sized and procumbent, shape, both have a u shaped dental arcade. To the extent possible, compare sahelanthropus and ardipithecus to the others: how hominin do they seem to you, they seem fairly ape-like with assorted hominin features. It is like a middle ground between ape and hominin with equal parts of both: what features are more hominin like, sahelanthropus, less prognathism than apes, more horizontal nuchal plane. Ant (cid:1007)50 - lab (cid:1006: ardipithecus, smaller canines, similar molars and premolars, which features are more ape like, sahelanthropus, supraorbital torus, temporonuchal crest, larger canines, ardipithecus, u-shaped dental arcade, sharpened canines, diastema, prognathism, temporonuchal crest. But focus on the canine and molar size]: canines, larger canines in afarensis than in africanus, no diastema in africanus, molars, larger in africanus than in afarensis.
