The following is an abbreviated list of major skeletal criteria used in studying primate crania. Some of these have already been discussed in class. Using the definitions of traits below and the scoring, complete the chart. Skeletal Characteristics General points: New World monkeys have smaller facial skeletons than Old World monkeys Old World monkeys have a long and prominent snout compared to New World monkeys Prosimians are small compared to the rest of the primate order Sagittal Crest: A cresting of bone that runs down the middle (midline) of the skull, along the sagittal suture in mammals and some primates. It is a site of muscular attachment for mastication. Scoring: Pronounced/Reduced/Not present Location of orbit : Is it on the side or is it placed forward? Forward facing eye orbits area a characteristic of primates in general, allowing for binocular vision. Scoring: Forward/Side Postorbital bar : Eye sockets bounded on sides by a ring of bone. Scoring: Present/Absent Postorbital enclosure : Eye sockets completely encased by bone. Scoring: Present/Absent Dental Formula : The dental formula of humans, apes, and all Old World monkeys: for upper and lower. The dental formula for New World monkeys: for both upper and lower. Prosimians have slightly varied dental formulae and the upper and lower formulae can differ. Scoring: the dental formula, i.e. (upper and lower)
