EXERCISE 4 FOSSIL NEW WORLD AND OLD WORLD MONKEYS Work in a small group or alone to complete this exercise. Use the fossil descriptions and images here and any supplemental material provided by your instructor to answer the questions that follow. Mystery fossil genus A has been dated to the late Pliocene and early Pleistocene. Its canines were sexually dimorphic, and it had bilophodont molars. Its postcranial traits indicate that it was a terrestrial quadruped, and its overall body size was over 55 lb (25 kg). Mystery fossil genus B has been dated to the early Miocene. It is estimated that adults weighed around 2 lb (1 kg), with some sexual dimorphism possible in body weight and canine size. Which of these mystery fossils is a fossil Old World monkey? Which of these mystery fossils is a fossil New World monkey? Describe at least two traits you used to make these identifications. (Be sure to describe how each trait differs between the two mystery fossils—for example, fossil A has this trait, but fossil B does not.)
