Bell Glade Rock Pit [Belle Glade Mbr, Bermont Fm] (Pleistocene of the United States)

Where: Palm Beach County, Florida (26.7° N, 80.7° W: paleocoordinates 26.7° N, 80.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Belle Glade Member (Bermont Formation), Middle Pleistocene (0.8 - 0.1 Ma)

• STRATIGRAPHIC RELATIONS: Presumably from Bermont Formation, formely referred to as the "Glades" unit (McGinty 1970, Hoerle 1970), or Unit A (Olsson 1964), which overlies the Caloosahatchee Fm (Plio-Pleistocene) and underlies the Pleistocene Fort Thompson Fm. THICKNESS: Unknown thickness of unit, or strata from which collection was obtained. AGE: Middle Pleistocene. STRATIGRAPHIC POSITION: Unknown position within formation, presumably collection represents the entire unit.

• formation-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; unlithified, shelly/skeletal, silty marl

• ENVIRONMENT: Similar to those occuring off the ocean side of the Florida Keys . Greater proportion of unit represents soft mud or marl with 1 or 2 fathoms of sea water and large beds of Thalassia or "turtle grass". Sand bars, indicated by vast numbers of Oliva in the deposit, must also have existed, for Oliva would only have lived in such a situation. Rocky or reef bottom would appear to have been restricted, for species which require such an ecological sitiation prove scarce.
• SPECIFIC LITHOLOGY: Shell marl and mudstone. LITHIFICATION: Unlithified on the basis of facies description and figured specimens.

Size class: macrofossils

Preservation: original aragonite, original calcite

Reposited in the FMNH

Collection methods: bulk, quarrying, surface (float),

• COLLECTOR: R.C. Hoerle, S. Hoerle, T.L. McGinty and P. McGinty. REPOSITORY: Probably within private collections, though much of T.L. McGinty's collection is now reposited at FLMNH.
