The mammoth lumbers through our imaginations when we think about the world during the most recent Ice Age. They’re just one of many giant creatures that our ancestors lived alongside and which became extinct when the climate changed. The giant ground sloth – a large herbivore that was endemic to the Americas – is another.

We can study these extinct animals from their bones – but also from the preserved footprints they left in the mud. But these footprints are often hard to find – and while they can tell us about the presence of an animal, they don’t always tell us much about the animal itself, like how it walked, for instance. The giant ground sloth was unusual in that it walked on the outside of its feet.
