Geography
| Country: | Trinidad and Tobago |
| Coordinates: | 10.7° North, 61.1° West (view map) |
| Paleocoordinates: | 10.6° North, 60.3° West |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Neogene | Epoch: | Pliocene |
| Stage: | Zanclean | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Early/Lower Pliocene | ||
| Age range of interval: | 5.33300 - 3.60000 m.y. ago |
Stratigraphy
| Formation: | Talparo | Member: | Matura | ||
| Regional section: | Matura | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Collection is from the Matura Sand and Clay Member of the Talparo Formation. The Matura fauna is considered to be of early Pliocene age and is probably slightly younger than the Courbaril fauna. The Matura shell bed has variously been attributed to the Pliocene (Guppy 1864, 1867, 1874; Maury 1925; Kugler 1953; Woodring 1966) or Pleistocene (Kugler 1936). | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal,brown poorly lithified argillaceous,sandy "mixed carbonate-siliciclastic" |
| Includes fossils? | Y |
| Lithology description: From blocks of highly limonitic, brown coquina with intercalations of clay and silt. | |
| Environment: | shoreface |
| Geology comments: The Matura fauna is a typical tropical, nearshore assemblage. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
