About 50 km east of Holguín (Paleocene of Cuba)

Where: Cuba (20.9° N, 75.8° W: paleocoordinates 19.6° N, 62.0° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Paleocene (66.0 - 56.0 Ma)

• The nautiloids were found in a loose limestone slab in an area of complex geology. Because rocks exactly matching the matrix of the nautiloid specimens were not yet found in situ, the only way to determine the age independently was by microfossils. I. Bodrogi of the Hungarian Geological Survey identified, in thin-sections, an assemblage of calcareous algae (incl. Lithophyllum sp. and Lithothamnium sp.) and benthonic foraminifers (e. g. Spirillina sp., Triloculina sp.), associated with a rich planktonic foraminifera fauna with Globigerina cf. triloculinoides Plummer, suggesting a Paleocene age.

• bed-level stratigraphic resolution

Environment/lithology: lithified, white lime mudstone

• White micritic limestone

Size class: macrofossils
