Stratigraphy
| Formation: | Kirkwood | Member: | Shiloh Marl | ||
| Local section: | Avalon | Local bed: | 767 ft | ||
| Local order: | top to bottom | ||||
| Regional section: | Cape May | ||||
| Stratigraphic resolution: | group of beds | ||||
| 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. Collections from between depths of 700 and 815 ft | |||||
Lithology and environment
| Primary lithology: | poorly lithified sandstone |
| Includes fossils? | Y |
| Lithology description: Fossiliferous sandstone and quartzite. | |
| 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 |
| Collection method comments: Reposited in the ANSP collections. From Richards and Harbison (1943): "The Woolman Collection yielded miocene fossils between the depths of 375 amd 815 ft in an Avalon well. Unfortunately, the best collection of shells has no data as to depth. | |
| Taxonomic list comments:Exhaustive for Gastropoda, Bivalvia and Scaphopoda. Nomenclature is somewhat antiquated but provided to species resolution and authoritative. | |
