Hemphill County 6 (Miocene to of the United States)

Also known as UCMP V2832

Where: Hemphill County, Texas (35.8° N, 100.3° W: paleocoordinates 36.4° N, 97.4° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Miocene to Miocene (23.0 - 5.3 Ma)

• This is just below or may be included within bed no. 3 (Reed and Longnecker locality 16,1932, p. 65).

•The age of these beds is certainly Pliocene, and they are a southern extension of the Ogallala formation of Darton. The rich Hemphill middle Pliocene fauna on Coffee Ranch lies at the base of bed no. 1 (Reed and Longnecker, locality 20, p. 66), about 100 feet stratigraphically above this locality and about 22 miles south of it. The facts that the Hemphill specimens of Capromeryx are more advanced in their characters and more elevated in their stratigraphic position, suggest that the species C. texanus may belong to the upper part of the lower Pliocene.

•[JDM] Made minimum date Hemphillian, because Hemphillian Coffee Ranch is said to be stratigraphically above this locality

Environment/lithology: terrestrial; sandstone and gravel

• The few fossils found here had weathered from loose sands and gravels

Size class: macrofossils

Reposited in the UCMP

Collection methods: surface (float)

• The few fossils found here had weathered from loose sands and gravels.
