This is a bit of an experiment and still a work in progress. The Smithsonian has a mammoth skeleton for download, http://3d.si.edu/downloads/55 .
Mammoths are, of course, relatives of African elephants. But they are more comparable with Indian elephants.
Making a skeleton is a a lot of work and I wanted to see if I would be able to take an educated guess and turn the mammoth skeleton into an African (bush) elephant skeleton.
I am still going to ask people who know to review it, but for now here it is. I will probably use this slot to upload the updated versions.
The main reason I made this skeleton is not to get the skeleton itself but to have a base I can add a muscle system onto for animation.
