LA #7 – Functional Anatomy Introduction Functional anatomy studies the relationship between bone form and function, and is the basis for fossil interpretation. In this lab you will apply what you’ve learned about the skeleton and behavior to develop hypotheses and “make sense” of fossil materials. Instructions The lab is divided into several “stations,” each with a set of specimen images and corresponding questions for you to answer. Station 1 – Cranium Use the images of the Cranium A and Cranium B crania provided below to answer questions 1 – 7. Be sure to use the appropriate anatomical and directional terms in your responses. Cranium A Cranium B 1. Compare the size and shape of the frontal bones for Specimen A and B. Note any differences you observe.

2. For Specimen A, where is the widest portion of the cranium? 3. For Specimen B, where is the widest portion of the cranium? 4. Compare the overall shape of the occipital region for Specimens A and B and note any differences you observe. 5. Compare the facial skeleton and the braincase for Specimen A (think of the superior border of the eye sockets as the “dividing line” between the two). Which seems larger? 6. Compare the facial skeleton and the braincase for Specimen B, which seems larger? 7. Develop a behavioral hypothesis to explain at least one difference you noted between specimen A and B. Station 2 – Dentition Use the images of Specimens C – E to complete #8.
