USGS Loc. 10603 - White's Creek [Shoal River Fm] (Miocene of the United States)

Where: Walton County, Florida (30.6° N, 86.0° W: paleocoordinates 31.0° N, 83.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Shoal River Formation (Alum Bluff Group), Serravallian (13.8 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Shoal River Fm of the Alum Bluff, which lies between the Chipola Fm (Early Miocene) and the Chochtawatchee Fm [Early Pliocene). AGE: Early Miocene (Gardener 1947); Middle Miocene in Vokes (1990) and Portell et al. (2006), although Jones et al. (1993) reports 87Sr/86Sr ratios that yielded average age estimates of 12.4 Ma [=Serravalian]. STRATIGRAPHIC POSITION: From unknown position within formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; unlithified, calcareous marl and unlithified, calcareous sandstone

• marls, sands, clays, for the most part unconsolidated, in places highly calcareous

Size class: macrofossils
