Where: Walton County, Florida (30.6° N, 86.0° W: paleocoordinates 30.9° N, 83.3° 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 RELATIONS: From the "Whites Creek Beds" of Smith (1941), which is approximately in the middle of the Shoal River Fm.
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; unlithified, gray marl
Size classes: macrofossils, mesofossils, microfossils
Preservation: original aragonite
