Gomphotherium,closely related to mastodons,disappeared before the end of the Pleistocene. The 3 m (10 ft) tall creature,also known as Trilophodon or Tetrabelodon,resembled a modern elephant but had four tusks instead of two: two on the upper jaw and two on the elongated lower jaw. The lower ones are parallel and shaped like a shovel and were probably used as such. Unlike modern elephants,the upper tusks were covered by a layer of enamel. These animals probably lived in swamps or near lakes,using their tusks to dig or scrape up aquatic vegetation. This specimen was found in Nebraska. Royal Tyrrell Museum,Alta,Canada | |
