Albertonykus was nice enough to alert me to a bunch of papers about Ankylosaur feet and how they apparently look more like Sauropod feet than traditionally rendered.
Sadly the papers were all in technical speak which I can't read effectively enough to be sure of how to draw, and the diagrams only helped me a little bit. Hopefully someone will want to take a crack at them on the Palaeo-art Database once it launches here in the new year.
So I took a leap into the dark, which I sure is wrong.
So attack with feedback science enabled people. Let's get these feet fixed!
