Where: Florida (26.5° N, 81.2° W: paleocoordinates 26.6° N, 80.8° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Ayers Landing Member (Caloosahatchee Formation), Early/Lower Pleistocene (2.6 - 0.8 Ma)
• STRATIGRAPHIC RELATIONS: From the Ayers Landing Mbr of the Caloosahatchee Fm, Okeechobee Grp, which is overlain by the Nashua Fm, and overlies the Bee Branch Mbr of the Caloosahatchee Fm. Correlative with the James City Fm (Virginia and North Carolina), Waccamaw Fm (North and South Carolina), and the Rucks Pit Mbr of the Nashua Fm (Florida). THICKNESS: Varies between 1 and 3 m across areal extent. AGE: Early Pleistocene. Based on macrofossil biostratigraphy the unit is assigned to the late Calabrian. Here assigned to the Early Pleistocene. STRATIGRAPHIC POSITION: Checklist representative of entire member.
• member-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; unlithified, shelly/skeletal, gray, white, calcareous sandstone and unlithified, concretionary, brown, gray sandstone
Size class: macrofossils
