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• coordinate based on unpublished field data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: upper 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 approximately 418 m above the Jimol/Castilletes contact.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; pebbly siltstone
Size classes: macrofossils, mesofossils
Preservation: cast, mold/impression, original calcite
Collected by Hendy in 2013
Collection methods: surface (float), surface (in situ),
