Also known as STRI Sample 37204

Where: La Guajira, Colombia (12.0° N, 71.3° W: paleocoordinates 11.2° N, 68.0° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: upper Jimol Member (Jimol Formation), Burdigalian (20.4 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Jimol Formation, which conformably overlies the Uipta Formation (early Miocene) and is conformably overlain by the Castilletes Formation. This area and nearby collections have been previously mapped as Castilletes Formaton (late Pliocene-early Pleistocene). AGE: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From near the top of the Castilletes Formation, in upper (Paraguachon - informal) member; from 48 m below Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; poorly lithified, shelly/skeletal siltstone

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite
