Lithology description: SPECIFIC LITHOLOGY: Sandy buff glauconitic chalk, intensely burrowed, with creamy brown phosphates scattered and rotten. LITHIFICATION: Lithified, based on facies description.
Environment:carbonate indet.
Geology comments: COMMENTS: Shallow marine carbonate setting.

Collection method comments: COLLECTOR: W. J. Kennedy. REPOSITORY: Unknown, probably the BMNH.
Taxonomic list comments:COVERAGE: Exhaustive for ammonoidea, bivalvia, gastropoda, and other macrofossils. NOMENCLATURE: Not an authoritative publication and with somewhat antiquated nomenclature. Ammonoidea generally identified to species resolution while bivalves, gastropods and other macrofossils may not.
