Station 9792 (Eocene of Haiti)

Also known as W 316 F

Where: Haiti (19.5° N, 72.7° W: paleocoordinates 17.8° N, 72.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lutetian (47.8 - 41.3 Ma)

• Rests unconformably on volcanic rocks, probably of early of middle Mesozoic age, and has a thin but conspicuous conglomerate at its base. The Plaisance Limestone is approximately 100 m thick at its type section. Yellow limestone of Jamaica apparently of the same age as the Plaisance fauna, though more diverse. Correlated to the Claiborne Stage of the Gulf Coast and the Lutetian-Auversian stages. A Lutetian age is assigned based on faunal relationships.

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, gray, white, yellow limestone

• No precise environmental information reported in text. Beds dip 20-30°. The contact with overlying upper Eocene limestone is marked by a steeply inclined normal fault that strikes N 75° and dips SW. At other localities the Plaisance limestione is folded and crumpled like the upper Eocene limestone.
• Hard limestone, usually gray, yellow, or white, and remarkably pure.

Size class: macrofossils

Preservation: cast, mold/impression

Collection methods: quarrying,

• Collected by W.P. Woodring and T.W. Vaughan, March 4 1921.

Taxonomic list

• Small list of Mollusca, probably not exhaustive, other faunal groups (forams, corals, echinoderms) listed in text if present. Nomenclature antiquated (but should be precise as identified by W.P. Woodring and S.T. Stanton) and often limited to sp. determinations (owing to poor, moldic preservation). Identifications of corals by T.W. Vaughan, Echinoderms by R.T. Jackson, and forams by W.P. Woodring.
