Where: Trinidad and Tobago (10.3° N, 61.5° W: paleocoordinates 9.0° N, 56.3° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Flat Rock Member (San Fernando Formation), Oligocene (33.9 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From the informal "Bamboo Marl" [=Flat Rock tongue Mbr of the San Fernando Fm], which is a letarl equivalent of the Cipero Marl (Oligocene). AGE: Middle-Late Oligocene on the basis of large foraminiferal biostratigraphy. STRATIGRAPHIC POSITION: From the "Bamboo Clay, which separates Zones I and II of the San Fernando Fm.
