I suggest that you answer this by first setting up a table with dermatocranium, splanchnocranium, chondocranium, appendicular skeleton and axial skeleton across the top and fish, amphibian, reptile, bird, and mammal down the side. This is so that you have a way of comparing the information as you collect it.

You might want to start with definitions of the parts of the cranium from one of the on-line dictionaries.
Thanks for the tip!
