First and last name: _____________________ ANT 203: Biological Anthropology Laboratory Exercise 3 Primate Anatomy II /40 marks total, worth 5% This laboratory exercise is in three parts. You need to print this laboratory exercise document, bring it to your scheduled lab section, and complete the exercises and questions using the space provided during your lab period, then hand in the completed worksheet to your TA at the end of your lab period. All labs are due and should be submitted in hard copy at the end of the scheduled lab session. Late lab assignments will not be accepted, with no exceptions. Of the 12 scheduled labs, 8 lab assignments will be graded. Students will not know which labs will be graded until the end of each lab session. Purpose: This lab will teach you to identify members of various primate taxa and to tell them apart based on morphological features. Each station has different specimens set up, and you will visit three different stations in small groups. You are welcome to talk to members of your group to work through possible answers, but should complete the labs on your own. You may refer to the Primate Anatomy supplementary materials handout. Total: /40 marks Station 1: Catarrhini or Platyrrhini?, /14 marks This station will help you learn to discriminate between Catarrhine (Old World Monkeys and apes) and Platyrrhine (New World Monkeys) primates. /9 marks Specimen 1 Specimen 2 Specimen 3 Dental formula? Broad or narrow nasal opening? Platyrrhine or catarrhine? 1. Indicate the continent(s) where each specimen could be found in the wild. /3 marks

Name ___________________, ANT 203, Lab 3, page 2 2. Explain which primate morphological feature inspired the names platyrrhini and catarrhini, and why. /2 marks Station 2: Hominoid or Cercopithecoid?, /14 marks This station will help you discriminate between the hominoids (apes) and cercopithecoids (Old World monkeys). Hint: Most of the apes are much bigger than your average monkey. But, not all hominoids are bigger than all monkeys. /9 marks Specimen 1 Specimen 2 Specimen 3 Overall size Size of brain case relative to overall size of skull? Hominoid or Cercopithecoid? Y-5 or bilophodont teeth? (this is hard to see, so has been filled in) Bilophodont Y-5 Y-5 3. How did you tell apart the hominoid and cercopithecoid specimen(s)? /1 mark
