STRI Loc. 290605 [field] - Punta Gorda sud [upper Castilletes Fm] (Miocene of Colombia)

Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.3° N, 68.6° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: upper 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 approximately 278 m in regional section, approximately equivalent to 290461-290463; 1 m above 290604.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; poorly lithified siltstone

• ENVIRONMENT: Siliciclastic, fully marine salinity, perhaps lagoonal, 5-30 m.
• SPECIFIC LITHOLOGY: Consolidated silty matrix. LITHIFICATION: Poorly lithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: cast, mold/impression, original calcite

Collected by Hendy in 2013

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