Lithology and environment
| Primary lithology: | glauconitic,shelly/skeletal unlithified calcareous sandstone |
| Secondary lithology: | "shale" |
| Lithology description: the gosport sand is a deposit of early late eocene (bartonian) age, and consists of 2-10m of extremely fossiliferous, unconsolidated, glauconitic, calcareous quartz sand, with occasional indurated ledges and thin lenses of carbonaceous shale and lignite. | |
| Environment: | marine indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | mesofossils |
Collection methods and comments
| Collection excludes: | all microfossils,some macrofossils |
| Collection methods: | bulk,mechanical,sieve,field collection |
| Collection size: | 12751 |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: "Numbers of specimens reflect number of identifiable gastropod apices and total number of bivalve umbos; unidentifiable fragments were not counted." | |
