M. americanum, the American mastodon, is the youngest 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 related to overexploitation by Clovis hunters, and possibly also to climate change.
Mastodon in The Opening of the WorldEdit
Mastodons lived in the Raumsdalian Empire, and had a range which extended as far south as the area around Count Hamnet Thyssen's castle. When the Rulers from beyond the Glacier invaded Raumsdalia, many people mistook their riding mammoths for mastodons.
