Don't just create, build

Where do you begin? Well you don't have to start with all this detail when designing a character but I wanted something specific for my Troganite horse. It's the parts that make the whole when designing anything, and the saying is true that you can't build on a bad foundation, so even if it's a drawing of a biological structure it starts with a well adapted frame.

Banners

The old anthroanatomica banner is now retired after 1 year of service. Let me know what you think of the new banner style and layout. Many thanks to you all for looking and adding to what is essentially a debate on plausible anatomy! :)

Tails

Something that's puzzled me for quite a while now is how does a tail work on a biped. Lets take for arguments sake that we are retaining this feature even in some vestigial form. The bones that form the caudal vertebrae of any tail are of course that tiny group of coccyx bones in a human. Far from being just a human vestigial tail, the coccyx is the site for attachment for many important pelvic floor muscles including the muscles of the genitals. How then, could we keep both the functionality of the pelvic floor needed in bipeds to help keep everything 'in' as well as functioning as a birth canal, and the aesthetics of an animal tail. Would caudal bones diverge from the sacrum, or could the sacrum be formed to function like that of the coccyx?

A few sketched ideas on how the pelvic floor could exist in a biped with a tail.
