The arm bones are in there as well across the top part of the wing coming out of the shoulder.

It’s called digitigrade and dogs & cats show this orientation of the foot & ankle bones. Because your fingers & toes are “digits”. When you walk flat footed like a human, it’s called plantigrade, and the bottom of the foot is the plantar surface.

All mammals have to same bone structure in the limbs. All the bones in human ankles are in elephant ankles. Sometimes the bones are fused or repositioned, but they’re there!

Better tell the transplant docs that they won't be needing them anymore. Praise Jesus! (and Bob, of course)
