Andrewsarchus

This animal looks somewhat like a wolf, but it is bigger than a bear and possesses hoof-like nails instead of claws. Its short fur has similar coloration to that of a lion, except in darker patches along the top of its neck and back, surrounding its eyes, and tipping its tail and feet.
