Question

Materials Needed Station 1: Interpreting Fossils (Alternative to Specimens: Figure A on next page) If you find this as a fossil, list the types of inferences you can make about it. 1 What can you say about its evolutionary relationships? That is, what kind of creature is it? Be as detailed as possible, and classify it to as low a level as you can. Explain how you can tell. (Be sure to first explain how you determined whether or not it is a primate.) Station 1: Non human primate skeletal remains laid out on a table (either fragmentary or complete) Station 2: Partial/fragmentary remains of one or more different vertebrate species, preferably nonprimate, and either clearly recognizable or labeled (for example, a deer mandible, a crocodile scale, a squirrel skull, etc.) to represent associated faunal remains at a fossil site Station 3: Remains showing results of taphonomic processes; for example, a very fragmentary set of skeletal remains or, conversely, a complete or mostly complete skeleton; or, a bone with rodent gnaw marks (many cow and deer bones exhibit these) Note: Figures in the lab manual may be substituted for any of the above. What about the teeth? Does the dentition fit into one of the main functional classes you learned about in Chapter 11 (folivore, frugivore, insectivore, carnivore)? Explain how you know. 2 Was it an adult? (Hint: Look at tooth eruption and epiphyseal bone ends—refer to Chapter 7 if needed.) Explain how you can tell.

Answer 1

Dear Student,

T he Interpreting Fossils, 0 - This is a primate. which belongs to family adapoids, ancestors of strepsirhines. This is most likely the Adapts from Europe. This deduction's based on the relatively large brain size, sciel! structore; orbits and shortened spout. The scapula & heimeries bones as shown is also more arboreally adapted → Insectivore- becawe of small shoup pointy curls. © Agie - 16 to 20 years ( due to faction of epiphyseal plate at humerus) * larger canine moy explain that dece to 1 growth of enamel. and ridges that the skull belongs to an older animal than the other one © The humneral head is rounded and globalar whereas scapilar is expanded at the saprascopia -lee area & its shorter & broader making it ñore molile- arboreal. canhed with in Scarien

Hope this helps you ??
