Where: Puerto Rico (18.4° N, 67.0° W: paleocoordinates 17.6° N, 66.0° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Lares Limestone Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• correlates with the Catahoula (i.e., late Oligocene: see Dockerey 1986)

• bed-level stratigraphic resolution

Environment/lithology: marine; yellow marl

Size class: microfossils

Collected by W. A. Gordon

Collection methods: bulk, chemical, sieve,

• Lousiana State University collection

•samples consist of "washed residues" that I assume were chemically treated because most come from presumably lithified marls and limestones
