STRI Loc. 290447 - Puerto Lopez [middle Castilletes Fm] (Miocene of Colombia)

Also known as STRI Sample 17088

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• coordinate based on unpublished field data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 Jimol Formation, which conformably overlies the Uipta Formation (early Miocene) and is unconformably overlain by the Castilletes 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 approximately 189 m in regional section; same horizon as STRI Loc. 290443.

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; unlithified, shelly/skeletal siltstone

• ENVIRONMENT: Siliciclastic, shallow subtidal, 5-30 m.
• SPECIFIC LITHOLOGY: Unconsolidated silty 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 2011

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

• COLLECTOR: A. Hendy, 03/16/2011. REPOSITORY: Presently reposited at FLMNH, Gainesville.
