Geography
| Country: | Trinidad and Tobago |
| Coordinates: | 10.6° North, 61.3° West (view map) |
| Paleocoordinates: | 10.6° North, 60.5° 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: | Caparo Clay | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: SOURCE: collected from within a 15 ft lens of sandstone situated in the upper part of the Caparo Clay. STRATIGRAPHIC RELATIONS: The Calparo Clay Mbr is the middle member in the Talparo Fm. The Matura Fm is probably equivalent to the Calparo Clay. BIOSTRATIGRAPHY: no biostratigraphic data reported, but is assigned an Early Pliocene age in the text and correlated to the Marura Fm, also Pliocene in age. | |||||
Lithology and environment

| Includes fossils? | Y |
| Lithology description: Limonitic or glauconitic conglomerate sandstone. | |
| Environment: | estuary/bay |
| Geology comments: DEPTH: marine, neashore environment. SALINITY: slight brackish water influence. THERMAL TOLERANCES: no specific details, presumably tropical. | |
