Huntington Reservoir mastodons (Pleistocene of the United States)

Where: Sanpete County, Utah (39.6° N, 111.3° W: paleocoordinates 39.6° N, 111.3° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• there is a dubious 14C date of 7080 +/- 200 YBP plus 7590 +/- 100 and 7650 +/- 100 YBP dates "based on a 13C adjusted radiocarbon age"; these are all based on "the apatite fraction of the bone carbon" because there was "little extractable collage"

• bed-level stratigraphic resolution

Environment/lithology: sinkhole; unlithified, gray, yellow, sandy, conglomeratic claystone

• "sinkhole deposits"
• "a nearly 1-m-thick gray to yellowish-brown sandy and gravelly clay unit" that is "poorly sortedd"

Size class: macrofossils

• a "spear point or knife fragment" was "found about 1m from one of the fossil bones" but was "not recovered in situ" and there were no "butchering" marks on the bones

Collected by W. E. Miller, J. K. Rigby, J. Jensen, K. Stadtman, S. Robison

Collection methods: quarrying,

• unidentifiable "bone and tusk fragments" were recovered by "screening"

•Brigham Young University collection
