STRI Loc. 290672 - Aulechet-Castilletes Rd [middle Castilletes Fm] (Miocene of Colombia)

Where: La Guajira, Colombia (11.9° N, 71.4° 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• coordinate based on unpublished field data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 the middle Castilletes Formation; from 116 m above Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; lithified, shelly/skeletal, gray siltstone

• ENVIRONMENT: Shallow marine (0-15 m), siliciclastic, probably normal salinity.
• SPECIFIC LITHOLOGY: Unconsolidated, dark gray, shelly, 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),
