Dinosaurs are cool, but what about old mammals? We saw the famous ones on the big screen, so I'm going straight to the really weird (and usually huge) prehistoric mammals that deserve some attention.

You may already know the coolness of giant sloths from the Ice Age films, but this sloth spent most of its time looking for food in the sea and developed several adjustments in the sea to breathe and swim more efficiently. Speaking of cool sloths: Megatherium was also a giant ground sloth … the size of an elephant.

It was basically a huge armadillo that lived during the Pleistocene, and by "enormous" I actually mean "the size and weight of a small car". The first fossils may have been discovered by Charles Darwin himself, and the animal's name means "grooved tooth".

It existed in the Pleistocene and was about the size of a hippo. These guys (or at least their bones) may have been the source of stories about the man-eating cryptid known as "Bunyip". Australian Aboriginal cave paintings may show diprotodon-based human art, and aborigines have historically identified diprotodon bones as belonging to Bunyips. We believe that many of them have died during a long drought and that they could physically resemble a strange type of polled rhino.
Probably closer to orangutans than other existing monkeys (but still human enough to be super creepy), the Gigantopithecus blacki was the largest known hominid and probably roamed until about 100,000 Years through East Asia. They were up to 10 feet tall and weighed up to 1,300 pounds … really, giants once walked our earth. There is evidence that they lived on Earth at the same time as the early Homo sapiens and H. erectus . It's hard to imagine what early people must have thought when they came across such a massive human-like thing … it must have been terrifying. Unfortunately, we couldn't find as many of their bones as we wanted. it seems like many of them have been dragged away and gnawed for their calcium, possibly from giant prehistoric porcupines.
5. Horned Gophers

Scientists are not sure what the horns were for, as they are the only known rodent and the smallest known horned mammal. We suspect that they used the horns to defend themselves against predators. They don't seem to be able to use them to dig tunnels. It is also possible that they were bred as a mating display or to fight with each other, but the evidence that we have does not really support this idea – apparently they could not see it well, and the men and women both have the horns .
