Pleistocene rewilding The mountain tapir is the only extant non-tropical species of tapir. Predators of mountain tapirs include cougars, bears, and, less commonly, jaguars. Good introduction areas might include forested ecosystems of the west and east coasts, and the more scrub-like or wetland ecosystem of the south. During the Pleistocene, large populations of Proboscideans lived in North America, such as the Columbian mammoth and the American mastodon. The mastodons all became extinct at the end of the Pleistocene era, as did the mammoths of North America. However, an extant relative of the mammoth is the Asian elephant. It now resides only in
Boaz mastodon and Anderson Mills mastodon the Anderson Mills mastodon dated to 12,910 ± 150 calendar years BP. Meanwhile, the Boaz mastodon is one of the most recent ever found, and dated to 12,220 ± 190 calendar years BP. Boaz mastodon and Anderson Mills mastodon The Boaz mastodon is the skeleton of a mastodon found near Boaz, Wisconsin, USA, in 1897. A fluted quartzite spear point found near the Boaz mastodon suggests that humans hunted mastodons in southwestern Wisconsin. Although the mastodon on display at the Geology Museum has long been known as "the Boaz Mastodon", it was recently discovered that two bones from the Boaz
