Smart Stuff with Twig Walkingstick: Your Home, Where Giant Buffalo Once Roamed (for the Week of Sept. 2, 2007)

August 29, 2007

Q. Dear Twig: The mammoth. The mastodon. The saber-toother tiger. Where'd they live? Where'd they go?

A.: They lived in North America (and, in some cases, in other places, too) until the end of the Ice Age: about 10,000 years ago. Then they went extinct.

So did many other big mammals, like the giant beaver, Shasta ground sloth, American lion and giant short-faced bear.

Imagine! A beaver as big as a bear (the giant beaver). A bear even bigger than today's grizzly bear (the giant short-faced bear). A sloth the size of a cow (the Shasta ground sloth). A cat the size of a St. Bernard dog with Ginsu knives for two of its teeth (the saber-toothed cat, or saber-toothed tiger). Plus big honkin' elephant cousins such as the woolly mammoth and American mastodon.

All in our home, North America! All on land that you live on today — maybe even your own backyard! Imagine taking the trash out at night.

Next: Why you don't have to run!


P.S. Call them "megafauna" ("MEG-uh-fawn-uh"): the biggest animals of a time or a region.

Notes: Extinct North American megafauna, all of them too big to fit in a Prius or at least unlikely to try, include the stag moose, dire wolf, western horse, ancient bison, giant armadillo, scimitar cat, yesterday's camel, imperial mammoth and Jefferson's ground sloth.
