Trinidad [Courbaril Mbr, Morne l’Enfer Fm] (Pliocene of Trinidad and Tobago)

Where: Trinidad and Tobago (10.2° N, 61.6° W: paleocoordinates 10.2° N, 60.9° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Courbaril Member (Morne l'Enfer Formation), Early/Lower Pliocene (5.3 - 3.6 Ma)

• LITHOSTRATIGRAPHY: From the Courbaril Sand and Clay Member of the upper Morne l'Enfer Formation. AGE: Considered to be of early Pliocene age and is probably slightly older than the Matura fauna. STRATIGRAPHIC POSITION: Composite list for member.

• member-level stratigraphic resolution

Environment/lithology: shoreface; poorly lithified sandstone and claystone

• The assemblage as a whole points to a nearshore environment, with some brackish influence (compared with Melajo Clay assemblages).
• LITHOLOGY: Poor reporting of lithologies. Named as the "Courbaril Sand and Clay Member", so these lithologies are assigned. LITHIFICATION: Poorly lithified, based on figured specimens.

Size class: macrofossils

Collection methods: COLLECTORS: Unknown. REPOSITORY: Unknown.
