Also known as STRI Sample 16975, 16983

Where: La Guajira, Colombia (12.0° N, 71.4° W: paleocoordinates 11.2° N, 68.1° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: lower 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: Probably from the lower section of Jimol Formation, not far above Shirrua type section, probably slightly higher stratigraphically than STRI 290412; 148 m below Jimol-Castilletes Fm contact.

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; poorly lithified, medium-grained, shelly/skeletal sandstone

Size classes: macrofossils, mesofossils

Preservation: original calcite, replaced with calcite
