Geography
| Country: | Seychelles |
| Coordinates: | 9.4° South, 46.4° East (view map) |
| Paleocoordinates: | |
| Basis of coordinate: | estimated from map |
| Geographic resolution: | local area |
Time
| Period: | Quaternary | Epoch: | Pleistocene |
| Stage: | Late Pleistocene | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Late Pleistocene | ||
| Age range of interval: | 0.129 - 0.0117 m.y. ago |
Stratigraphy
| Formation: | Esprit Limestone |
Lithology and environment
| Primary lithology: | "limestone" |
| Lithology description: 8 m of fine-grained calcarenites | |
| Environment: | lagoonal/restricted shallow subtidal |
| Geology comments: a quiet lagoon from 5 to 20 m deep, which in time shallowed, exposed rocks represent only a tiny fraction of the total area of the atoll, evidence of the general environmental framework is lacking | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | poor |
| Abundance in sediment: | abundant |
Collection methods and comments
| Collection methods: | field collection |
| Reason for describing collection: | paleoecologic analysis |
| Museum repositories: | BMNH | Collection dates: | 1969 |
| Collection method comments: June-September 1969, small additional quantity in 1973 | |
