- 2. Categories besed on its shale Draw a brachycephalic skull and a dolichocephalic skull. Explain the difference between them. 3. Draw and describe a leptorhine, mesorhine, and platyrhine nasal opening. ?1. In terms of the differences between the opossum, bird, bat, and mole skeletons which you examined, which is most like the human (and therefore, most primitive or generalized) ? 2. Which is least like the human and, therefore, the most specialized ? 3. Most anatomists consider bats more specialized than moles; but what important differences can you see between the mole's forelimbs and that of humans? Why is the front limb of the mole so specialized? Can you identify: the humerus, clavicle, and scapula in the mole? 4. Compare the bat to the bird. Identify the humerus in each. Where is the bat's ulna? Are there any remnants of it? How is the bat's wing membrane supported by its skeleton? Be precise. (You may wish to examine a preserved bat on the display table.)
