STRI Loc. 110035 - W of Kabarauremana [middle Jimol Fm] (Miocene of Colombia)

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• coordinate based on unpublished field data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: middle 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. AGE: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From a faulted area, but presumably in middle part of Jimol Formation; from approximately 100 m below Jimol/Castilletes Fm.

• bed-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified mudstone

• ENVIRONMENT: Offshore marine (>30 m), siliciclastic.
• SPECIFIC LITHOLOGY: Poorly-lithified, grey laminated mudstone. LITHIFICATION: Poorly lithified, as determined in the field.

Size classes: macrofossils, mesofossils

Preservation: original aragonite

Collected by Hendy in 2014

Collection methods: surface (float), surface (in situ),
