This is the title for a book that Marc Davis had been working on for many years. Unfortunately it was never published, but all of Marc's research still exists. Motion range as well as comparative anatomy among a number of species are top subjects. Also many studies of bone and muscle structure.
The book was intended for artists, animators and physicians. I will post Marc's initial sketches (he also produced final illustrations) from time to time, and I highly recommend studying them. Print them out and create your own Marc Davis Anatomy booklet!
I believe some of this material dates all the way back to the late 1950s.
