Megistotherium & Karianne
These are just a few of the great images over at the Olduvai George blog. Here at the Palaeoblog we love good art almost as much as palaeontology and this site offers lots of wonderful palaeo (and other) art, and tips on drawing digitally (even though these examples are painted in traditional fashion in acrylic on illustration board). Highly recommended.
