Lowndes County

ENVIRONMENT: Not stated. Schulte & Speijer (2009): The lowered fossil content in the McBryde Limestone Member, as compared to the Turritella Rock (described as a shallow, inner neritic setting), as well as the significantly smaller grain-size of the components, and decreased amounts of coarse silicic detritus, suggest a more distal depositional environment. Open-marine conditions are also indicated by the presence of nautiloids, and more common planktic foraminifera in the marl intervals. In the sandy bioclastic limestones, fossils appear to be reworked from nearshore settings (e.g., algae) and the large grain size of the constituents suggests a high-energy environment, probably above storm wave or even wave base (i.e., <25 m). The condensed claystone intervals around the maximum flooding surfaces may have been deposited below storm wave base, probably in a water depth exceeding 30 m.
