London – Kensington – Natural History Museum (Megatherium)

A plaster cast of Megatherium, one of the largest mammals that has lived, and it’s effectively just a giant ground sloth. This cast was made in 1848 from two different skeletons and it’s been on display in the museum since 1850. I’m sure that, even at this large size, it still looked quite adorable and the animal could be as long as six metres in length from head to tail. They were found in the Americas and one of the reasons thought for their extinction around 12,000 years ago is human movement into the areas where they lived.
