Stratigraphy
Formation:Forest Hill
Stratigraphic resolution:formation
Stratigraphy comments: The upper part of the Forest Hill Formation consists of estuarine clays and sands which locally contain a marine fauna. In Wayne county at localities 75a and 88a, numerous, wel preserved fossils were collected from sand lenses in this interval. Also present in this interval are leaf fossils which occur along beddind planes in the clay. These estuarine and marine sediments are the initial stage in the marine transgression of the Mint Spring seaway.

Taxonomic list comments:The list states abundances in catagories. "R" = 1-9 specimens, "C" = 10-99 specimens, and "A" = 100+ specimens. There are actual number abundances listed for both rare and common. The actual abundances for the "abundant" specimens is not known

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.
