Lithology and environment
Primary lithology: unlithified silty,sandy "limestone"
Lithology description: An impure silty to sandy chalk with subordinate amounts of clay, sand and chalky limestone is approximately 30m thick.
Environment:shallow subtidal indet.
Taphonomy

Collection methods and comments
Collection methods:bulk,surface (in situ),field collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: Some areas were sampled on the outcrop surface, others were excavated with pick and shovel and some more specimens came from screenwashing bulk sediments.
Taxonomic list comments:Faunal lists were supplemented by a US Geological Survey Open File Report (Sohl and Koch 1983). Most of the species listed from Ripley, Lower and Middle Prairie Bluff were taken from the Open File Report.
