STRI Loc. 290824 - Kaitamana [middle Castilletes Fm] (Miocene of Colombia)

Also known as AH140134; AH140133

Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.2° 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• coordinate based on unpublished field data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: In faulted block, but likely from lowermost part of the middle Castilletes Formation; from 104 m above Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified siltstone

• 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 calcite

Collected by Hendy in 2014
