This may look like a dinosaur, but it's actually a mammal.

The bones of this magnificent giant sloth were sent to London in a box from South America in the 1800s.

Richard Owen examined them and confirmed they came from Megatherium . He described its structure, and how it probably spent its days, in brilliant detail.
