Has anyone got any idea as to where to find editable line drawings of the standard set of animal skeletons, (deer, pig, sheep, bovine, etc.) standing with a side view in some form of vector graphics that are freeware? Or better yet in 3D?

What I am aiming to do is to select a particular bone, and fill it with a pattern to show which part of the animal is represented in the bone assemblage.

Any leads gratefully received.
