Holy cow, you climbed all the way to the tippy-top of Denali (also known as Mount McKinley), the tallest mountain in North America. Way to go! On your way down the mountain, you encounter a large and hairy amniote and two of her offspring that are suckling from a couple of their mother’s six nipples. The mother, who has four limbs with long claws extending from its fingers and toes, stands on its two back limbs and growls at you. As she growls, you can feel her warm breath, despite the chilly mountain air. You also notice that she has two long, conical, piercing canines in front of a series of shorter, bumpy, crushing molars protruding from the single bone of her lower jaw. What type of animal have you encountered?
