STRI Loc. 290802 - Kabarauremana [lower Castilletes Fm] (Miocene of Colombia)

Also known as AH140102

Where: La Guajira, Colombia (12.0° N, 71.3° W: paleocoordinates 11.2° N, 68.0° 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• coordinate based on unpublished field data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 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: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From very base of Castilletes Formation, in lower member; from approximately 26 m above Jimol/Castilletes contact.

• bed-level stratigraphic resolution

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

• ENVIRONMENT: fully marine, siliciclastic, shallow sub tidal.
• SPECIFIC LITHOLOGY: Poorly consolidated silty matrix. LITHIFICATION: Poorly lithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original calcite, replaced with calcite

Collected by Hendy in 2014

Collection methods: surface (float),

• COLLECTOR: A. Hendy, 01/19/2014. REPOSITORY: Presently reposited at Uni. Norte, Colombia.
