STRI Loc. 430053 - Kaitamana [lower Castilletes Fm] (Miocene of Colombia)

Also known as STRI Loc. 290666-1

Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.1° N, 68.1° 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• coordinate based on unpublished field data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 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: In faulted block, but likely from lower part of Castilletes Formation; from 55 m above the Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; poorly lithified siltstone

• ENVIRONMENT: Shallow marine, probably lagoonal, with nearby freshwater input.
• SPECIFIC LITHOLOGY: Poorly consolidated silty matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite

Collected by Hendy in 2013

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

• COLLECTOR: A. Hendy, 01/23/2013. REPOSITORY: Presently reposited at Universidad del Norte, Colombia.
