America's Serengeti

Many people travel to North America to watch wildlife. Grizzly bears, moose and bison are among the impressive animals on view, but today's wildlife is nothing compared to what the first people on the continent would have seen.

Towering above these were huge woolly and Columbian mammoths and American mastodons. There were beavers and capybaras the size of bears and the bears were bigger still. The giant short-faced species outweighed even the largest of today's polar bears.

The scimitar-toothed cat, the American lion (the same species as those now found in Africa) and, most notorious of all, the sabre-tooth. But what happened to all these creatures?
