Left to Right: Lizard, Turtle, Crocodile, Bird, Cat
This is a collection of drawings I did based on photos of skulls from my Comparative Vertebrate Anatomy class in college. One of my favorite classes, and a great area of biology. Each skull shown above consists of the same bones, just adapted for different purposes. Had I color-coded each bone, you could see how varied each individual bone can be, but the general shape of the skull conveys the same idea.
