Where: Walton County, Florida (30.7° N, 86.1° W: paleocoordinates 31.0° N, 83.4° 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
Size class: macrofossils
