Where: Trinidad and Tobago (10.4° N, 61.3° W: paleocoordinates 10.1° N, 58.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From unknown lithostratigraphic unit. THICKNESS: Unknown AGE: Stated to be "Middle or Lower Miocene" in text, but potentially could be younger in more recent revisions; a Middle Miocene age is assigned here. STRATIGRAPHIC POSITION: Unknown.

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified siliciclastic sediments

• SPECIFIC LITHOLOGY: Unknown, presumably siliciclastic. LITHIFICATION: Assumed to be poorly-lithified based on facies description and figured specimes (largely free of sediment).

Size class: macrofossils

Collected by Penny, Bullbrook; reposited in the USNM

• COLLECTORS: F. W. Penny and J. A. Bullbrook (unknown date, but presumably during the 1910's-early 1920's). REPOSITORY: USNM.
