SC-179 (Paleocene of the United States)

Where: Park County, Wyoming (44.3° N, 109.0° W: paleocoordinates 49.7° N, 90.3° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Clarkforkian (56.8 - 55.8 Ma)

• meter level revised from 1060 to 1080 m by Bowen and Bloch 2002; this value would place the collection below SC-78 and very close to the bottom of chron C24r based on Butler et al. 1981

Environment/lithology: terrestrial

Reposited in the UMMP
