I'm not sure if this image is entirely accurate as a depiction of Andrewsarchus. The animal was mostly likely a hoofed predator (odd as that sounds to our hears). This is illustration appears to show an animal with clawed-feet, entirely different than the hooves one would expect of an a artiodactyl (e.g. pigs, cows, hippos...)
It's a nice illustration, I'm just not sure it's an realistic one. On the other hand, lacking any fossil foot bones....?
