It is thought that the American Mastodont
, Mammut americanum (Kerr), became extinct about 10,000 years ago (Meltzer and Mead 1983), soon after the major climactic shift to early postglacial conditions.

Later, Quimby (1960) stared that the distribution of fluted points and known mastodont
remains in Michigan was related to the probability that early humans hunted these proboscideans.
Proboscideans from the Pleistocene of Michigan are the American mastodont
(Mammut americanum) and mammoth (Mammuthus spp.
Questions about Ice Age mastodonts
and mammoths and their need for salt were originally brought to light in the Great Lakes region by a consideration of the large number of mastodont
and mammoth records confined in space and time in Michigan (Holman et al.
In the paper to follow he not only reported mastodont
remains from 36 Michigan counties but commented on mastodont
remains discovered in the state before his time (Winchell 1861; Lane 1902, 1906; Dice 1920; Hay 1923).
