When Ohio University integrative biologist Nancy Stevens peered into a drawer in the wooden cabinets on the top floor of a Nairobi museum in 2010, she saw a chunk of rock containing massive teeth and knew she had come across something important. The overlooked fossils stored at the National Museums of Kenya belonged to one of the largest meat-eating mammals ever to walk the Earth, a beast called Simbakubwa kutokaafrika that stalked Africa 22 million years ago, according to research by Stevens and co-author Matthew Borths published on Thursday. Bigger than any carnivorous land mammal alive today – even a polar bear – Simbakubwa’s skull was the size of a rhino’s, its 20-centimetre canine teeth as large as bananas. It weighed about a ton and was 2½ metres snout to rump.
