STRI Loc. 290611 [field] - Puerto Lopez Ridge [middle Castillertes 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• coordinate based on unpublished field data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 approximately 180 m in regional section.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; unlithified sandstone

• ENVIRONMENT: Likely reduced salinity; lagoonal; 0-5 m.
• SPECIFIC LITHOLOGY: Unconsolidated sandy matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original aragonite

Collected by Hendy in 2013

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

• COLLECTOR: A. Hendy, 03/18/2013. REPOSITORY: Presently reposited at Univesidad del Norte, Colombia
