Where: Florida (26.4° N, 80.7° W: paleocoordinates 26.4° N, 80.7° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Bermont Formation, Middle Pleistocene (0.8 - 0.1 Ma)
• STRATIGRAPHIC RELATIONS: From unknown member of the Bermont Fm (originally coined "unit A" by Olsson and Petit, 1964), Okeechobee Grp, which is overlain by the Belle Glade Mbr. Correlative with the Flanners Beach Fm (North and South Carolina). THICKNESS: Varies between 4 and 20 m across areal extent. AGE: Middle Pleistocene. Based on uranium isotope dating the unit is dated as middle Pleistocene, Aftonian. STRATIGRAPHIC POSITION: Checklist representative of entire formation.

Size class: macrofossils
Preservation: original aragonite
Reposited in the FMNH, USNM
• COLLECTORS: Multiple collectors, probably including Mansfield, A. Olsson, and R. Petit. REPOSITORY: USNM and Florida Museum of Natural History.
