Also known as Coon Creek; UW V-73003; YM-418
Where: Big Horn County, Wyoming (44.6° N, 108.5° W: paleocoordinates 49.4° N, 91.3° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Willwood Formation, Wasatchian (55.8 - 50.3 Ma)
• Gingerich and Deutsch (1989) state that all specimens of Arfia shoshoniensis are from 1645 to 1780 m in the Elk Creek section, and Rose and Bown's Plesiadapis dubius record is a significant upwards range extension, so I have used the lower value as a minimum
• group of beds-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Reposited in the UMMP, UW, YPM
