Mystery fossil genus A has been dated to the late Pliocene and early Pleistocene. It had two premolars in each mouth quadrant and bilphodont molars. Its canines were sexually dimorphic, and males had slightly larger and longer crania than females. Its postcranial traits indicate it was a terrestrial quadruped, and its overall body size was considerably larger than its living primate relatives. Mystery fossil genus B has been dated to the early Miocene. It had three premolars in each mouth quadrant and sexually dimorphic canines. Its teeth indicate a frugivorous diet. It had a medium body size similar to its living primate relatives. Required:
a. Which of these mystery fossils is a fossil Old World monkey?
b. Which of these mystery fossils is a fossil New World monkey?
c. Describe two traits you used to make these identifications. (Be sure to describe how each trait varied in the two mystery fossils.)
