• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Tennesseean zone, Paradise Formation, Carboniferous (358.9 - 298.9 Ma)
• formation-level stratigraphic resolution
Environment/lithology: marine; shale and sandy limestone
•bearing abundant but fragmentary
•mollusks. A fairly large
•fauna, obtained mostly from the
•lower limestone bed, is listed, but a
•much greater number of species is
•undoubtedly present whose identification
•awaits the finding of better
•specimens than the member ordinarily

Size classes: macrofossils, mesofossils
Preservation: original calcite
