STRI Loc. 290630 [field] - Patajau Norte [lower Castilletes Fm] (Miocene of Colombia)

Where: La Guajira, Colombia (11.9° N, 71.3° W: paleocoordinates 11.2° N, 68.0° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: lower Castilletes Member (Castilletes Formation), Burdigalian (20.4 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware 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 the contact between the Jimol and Castilletes Fms.

• bed-level stratigraphic resolution

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

• ENVIRONMENT: Fully marine; likely lagoonal; 0-5 m; siliciclastic.
• SPECIFIC LITHOLOGY: Poorly consolidated silty matrix. LITHIFICATION: Poorly lithified, as determined in the field.

Size classes: macrofossils, mesofossils

Preservation: cast, mold/impression, original calcite
