Here are some old and new photos of skulls I cleaned. With the exception of the sugar glider, these are all local North American species. 

Skunk, Coyote, Bear, Deer.

Crow Skull

Marrow cavity of a groundhog pelvis. 

Cervical & thoracic vertebrae from a groundhog. Most burrowing animals have robust neck vertebrae that are tightly joined. 

A closeup of the sugar glider skull. Notice the missing coronoid process on the jaw and the broken zygomatic arch. 

This is a detail shot of the front paw of the sugar glider that I put together here. It’s still articulated by natural connective tissue.
