| Mastodons fed on trees and shrubs in both the boreal and tropical rain forests of the New World while giant ground sloths and glyptodonts fed in Mexican deserts. |
| Scientists tell us that around 14,000 years ago North America was the home of large populations of mammoths and mastodons. |
| These extinctions included animals such as mammoths and mastodons, the saber-toothed cat, ground sloths and native American horses and camels. |
| Also this period saw the appearance of the mastodons, raccoons, and weasels. |
| In this scenario, humans moved rapidly through the continent, slaughtering mammoths, mastodons and other large prey as they went. |
| Near the corner of Wilshire and La Brea, tourists gape at the remains of saber-toothed cats and mastodons dredged out of prehistoric tar pits. |
