American mastodon

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.
