A rhino-sized, wolf-like carnivore, Andrewsarchus is actually a relative of our familiar hoofed animals and a distant relative of the early whale, Basilosaurus. Its fossils are usually found around water, and as single specimens, so it seems that these animals might have been solitary scavengers along riverbanks and tide lines.

SIZE: 6 feet tall and 16 feet long, with a skull around 33 inches long
