Where: Wayne County County, Mississippi (31.0° N, 88.7° W: paleocoordinates 31.3° N, 82.3° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Red Bluff Formation, Rupelian (33.9 - 28.1 Ma)
• Type Section of Red Bluff
• formation-level stratigraphic resolution
Environment/lithology: offshore; unlithified, gray, silty claystone and ironstone
Size class: mesofossils
Preservation: original aragonite, original calcite
Collection methods: surface (in situ),
• bivalves only**abundances are given as counts ONLY for those species with fewer than 100 specimens - for 100 or more, he just gives "A" for "abundant". In the case where a collection includes an "A", we enter abundance classes for species instead of counts as follows: Fewer than 10 specimens = R (rare)10 to 99 specimens = C (common)Greater than 99 specimens(Dockery's "A") = A (abundant)In this reference, "specimens" equals "valves"
•Categories are listed in the comments field, absolute abundances are given in the abundance field.
•Since taxa with greater than 99 specimens were not counted with absolute abundances, these were reported with category "A" for abundant.
