Les restes de faune terrestre, qui ont surtout ete ramasses sous la forme de debris de plage allochtones a Pauline Cove, prennent la forme de restes de chevaux du Yukon en predominance (Equus sp.), parsemes de quelques specimens de bisons priscus (Bison priscus), de proboscidiens (Mammuthus primigenius et d'un seul specimen de Mammut americanum
), ainsi que d'autres mammiferes de taille moyenne et de grande taille.
The Dollens Mastodon (Mammut americanum
) Locality, Madison County, east central Indiana.
Characters of Mammut americanum
.--The tusks are without enamel.
The small remaining portion of the long bone could be that of either Mammuthus imperator, Mammuthus columbi or Mammut americanum
, but given the stratigraphic location, the remains are unlikely to be those of Mammuthus imperator.
It was during a return visit to the locality in December 1982 by LDA and JIM that material was collected involving at least one individual Mammut americanum
represented by a mandibular tooth (MSM p7699) and fragments of enamel.
The new evidence with which these issues are being addressed (Fisher 1984a, b) is at present limited to late-glacial occurrences of Mammut americanum
, the most frequently reported element of our fauna, but extension of this work is anticipated to incorporate other times and taxa as well.

40 km SW Fain Ranch Locality has yielded remains of a mastodon (Mammut americanum

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.
This primary tooth of USNM 2225 is unusually short for a M3 of Mammut americanum
, which normally is about 160 to 225 mm long (Skeels, 1962; Lucas, 1987).
