On 5 July 1992, while digging a trench for drainage tile in his Warren County cornfield, Larry Shafer encountered teeth and jawbone fragments of the American mastodont
Intestinal Contents of a late Pleistocene mastodont
from mid-continental North America.
All of the discussants at this yearly forum doubtlessly would agree that the most awesome and important members of the Pleistocene fauna are the mastodonts
and mammoths, huge proboscideans (elephant-like beasts) that were the dominant members of the terrestrial community of the time.
Chronology: The most recent dated record is 11,240 [+ or -] 80 ybp (Wilkinson Giant Beaver Locality), and the oldest dated record is 15,540 [+ or -] 70 ybp (Shafer Mastodont
When the State Museum was relocated from its former home in the State Education Building, the Cohoes Mastodont
was considered too fragile to move.
-- Dental remains of the American mastodont
are recognized by their relatively thick enamel (6.2 mm on ET 5403), smooth occlusal surface, and the absence of additional enamel plications characteristic of gomphotheres.
Comments: Other macroscopic subfossil records from Indiana include Prairie Creek Site, Daviess County (Whitehead & Jackson n.d.); Blueberry Bog, Elkhart County (Swinehart & Parker 2000); Christensen Mastodont
Site, Hancock County (Whitehead et al.
Here, I document a supernumerary tooth in the American mastodont
(Mammut americanum) based on USNM (National Museum of Natural History, Smithsonian Institution, Washington, D.C.) 2225 from Pleistocene deposits near Afton, Oklahoma (see Hay, 1924 for locality information).
Johns, Michigan was mastodont
excavated by Daniel Fisher and Fisher 1987); or weakened ones could have been killed by human hunters.
Kapp) provided an update on records of mastodont
and mammoth localities (as well as other Pleistocene vertebrates) and, in doing so, posed several questions, including (1) Why were proboscidean sites in the state so abundant for such a short period of time (12,000 to 10,000 years ago), while other vertebrates were apparently so uncommon?
