| Paleocoordinates: | 17.2° North, 76.5° West |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Paleogene | Epoch: | Oligocene |
| Stage: | Rupelian | 10 m.y. bin: | Cenozoic 4 |
| Key time interval: | Early/Lower Oligocene | ||

Stratigraphy
| Geological group: | White Limestone | Formation: | Moneague | Member: | Brown's Town Limestone |
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Brownstown Limestone Mbr of the White Limestone Fm, which unconformably overlies the Gibraltar Limestone Mbr (Late Eocene), and is unconformably overlain by the Montpellier Limestone Mbr (Late Oligocene-Early Miocene). STRATIGRAPHIC POSITION: From a band in the lower part the Lepidocyclina undosa/Lepidocyclina favosa zone. LITHOSTRATIGRAPHY: Originally assigned to the Brown's Town Limestone. Replaced by Moneague Formation in Stevens (2004). | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal lithified "limestone" |
| Includes fossils? | Y |
| Lithology description: SPECIFIC LITHOLOGY: Limestones, with an abundance of gastropods. LITHIFICATION: Lithified, based on facies description. | |
| Environment: | shallow subtidal indet. |
| Geology comments: ENVIRONMENT: No environmental data reported in text, but apparently from shallow, carbonate facies. | |
Taphonomy
| Modes of preservation: | cast,mold/impression |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | very poor |
Collection methods and comments
| Collection methods: | surface (in situ),field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: COLLECTOR: Unknown. REPOSITORY: Geological Survey of Jamaica. | |
| Taxonomic list comments:COVERAGE: Limited, probably not exhaustive due to the poor preservation of the fauna and its limited investigation. NOMENCLATURE: Not an authoritative publication, and with antiquated nomenclature and no species-level taxonomic assignments. | |
