The elephant-like American mastodon was a distant relative of the mammoth, with whom it shared its ice age home. There have been over 200 mastodon fossil finds across North America, but they seem to have been most common along the eastern seaboard and in an area immediately south of the Great Lakes. In 1977, a unique find of a complete mastodon was made in Washington State. A human-made spear point was found embedded in the ribs and further investigation showed that the bones had healed around the spear point. This suggested that humans had attacked this animal, but that it had survived and died much later of old age.

Mastodons (Greek: μαστός "breast" and ὀδούς, "tooth") are an extinct group of mammal species related to elephants, that inhabited North and Central America during the late Miocene or late Pliocene up to their extinction at the end of the Pleistocene 12,000 years ago. Their genus name is Mammut, and they are members of the order Proboscidea. They lived in herds and were predominantly forest dwelling animals that fed on a mixed diet of browsing and grazing with a seasonal preference for browsing, in contrast to living elephants that are mostly grazing animals.
The American mastodon is the most recent and best-known species of the genus. They disappeared from North America as part of a mass extinction of most of the Pleistocene megafauna, widely presumed to have been a result of rapid climate change in North America, as well as the sophistication of stone tool weaponry used by the Clovis hunters which may have caused a gradual attrition of the mastodon population.
