Age range of interval:23.03000 - 15.98000 m.y. ago
Stratigraphy
Formation:Kirkwood Member:Shiloh Marl
Local section:Shiloh
Regional section:Cumberland
Stratigraphic resolution:member
Stratigraphy comments: No lithostratigraphic details or stratigraphic relationships provided in text. Equivalent in age and slightly older than the Calvert Formaiton of Maryland and Virginia. Overlain by the Cohansey Sand with a time transgressive contact, Kirkwood Formation is Burdigalian-Langhian in age.
Lithology and environment
Primary lithology: unlithified argillaceous,silty mudstone
Secondary lithology:pebbly sandstone
Includes fossils?Y
Includes fossils?Y
Lithology description: No lithologic data reported in text. Clayey to silty mudrock, massive sand, and thin pebble lenses.
Environment:coastal indet.
Geology comments: No geologic or paleoenvironmental data reported in text. Deposited in a sublittoral to nearshore environments
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection methods:field collection,survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:USNM
Collection method comments: Collections reposited in USNM and USGS collections. During the last century (written in 1942) when the marl industry was flourishing, there were numerous pits in this vicinity and fossils could easily be obtained from these diggings. According to Cook (1868) the material cam especially from the tributaries of Stow Creek. None of these pits are accessible at the present time except the Ayres Pits, which were reopened some 20 years ago.
Taxonomic list comments:Exhaustive for Gastropoda, Bivalvia and Scaphopoda. Nomenclature is somewhat antiquated but provided to species resolution and authoritative.
