This tiny, rather thin-shelled oyster is very easy to recognize. Pieces of limestone from the Clayton Formation often have their smooth, rounded lower valves protruding like little balls from them.
The species is a good guide fossil to the lower Paleocene (Danian/Midwayan), but is not found in many of the more common facies of that age in Georgia.
O. pulaskensis seems to have preferred open marine, clear water settings, and is most common in limestone facies of the Clayton. It is rarely, if ever, found aggregated as other oysters often do.
