Just for fun: Skull animations

Larry Witmer and his students at Ohio University study vertebrate heads. They now have a Youtube channel with almost a hundred animations of animal skulls, both living and extinct.

This one is an animation of the skull, brain endocast, and inner ear of the Oligocene creodont Hyaenodon (a carnivorous mammal which lived about 30 million years ago).
