Brought to you from 13 million years back, courtesy of the Denver Museum of Nature and Science, it’s Gomphotherium phippsi:
Gomphotherium may look a lot like an elephant, but he had his own unique approach. He apparently had a short trunk and rather than sporting two tusks, he had four — two in his upper jaw (in the usual elephant-style geometry), and two mounted in his lower jaw. His lower tusks were parallel, and are thought to have been used like a shovel to gather aquatic foods.
Gomphotherium evolved in the Early Miocene in North America, about 13.6 million years ago. During a drop in sea level, they were able to expand into Europe, Asia, and Africa — surviving for a total of 10 million years. This particular specimen lived 13 million years ago, in what is now Nebraska.
