Dinosaurs weren’t the only amazing beasts to have roamed North America. Take Uintatherium for example. This unusual looking mammal, reminiscent of a rhinoceros with its multiple knobby horns, lived about forty to forty-five million years ago in what is now Wyoming. In fact, Uintatherium means “Beast of the Uinta Mountains” where it was discovered. It was an impressive thirteen feet long and weighed in at around 4,000 pounds. In keeping with their proud assortment of amazing prehistoric animals, CollectA added one of these to their menagerie earlier this year.
