STRI Loc. 290642 - Puerto Lopez [middle Castilletes Fm] (Miocene of Colombia)

Where: La Guajira, Colombia (11.9° N, 71.3° W: paleocoordinates 11.3° N, 68.6° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: middle Castilletes Member (Castilletes Formation), Langhian (16.0 - 13.8 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: Langhian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From unknown position in the local section, slightly above 290639; from 151 m above Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; unlithified, shelly/skeletal siltstone

• SPECIFIC LITHOLOGY: Unlithified silty matrix; lensoidal shell bed and oyster bioherm. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite
