Where: Washington County, Tennessee (36.4° N, 82.5° W: paleocoordinates 36.6° N, 81.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Late/Upper Hemphillian to Late/Upper Hemphillian (10.3 - 4.9 Ma)
• "4.5 to 7 Myr (late Miocene to early Pliocene" (meaning late Hemphillian to early Blancan)"
•Samuels et al., 2018: "Considering the Gray Fossil Site fauna in total, a revised estimate of the age of the Gray Fossil Site is Early Pliocene near the Hemphillian–Blancan transition, likely between 4.9 and 4.5 Ma (Fig. 2)."
• member-level stratigraphic resolution
Environment/lithology: sinkhole; argillaceous, sandy siltstone and conglomerate
•"finely laminated clays, silts, and fine sands intermixed with isolated gravel lenses that fill a former sinkhole... up to 39 m thick... result of a small lake or pond that formed within the sinkhole" (Wallace and Wang 2004)
