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• coordinate based on unpublished field data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: 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 approximately 131 m in regional section.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; unlithified, shelly/skeletal siltstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite, original calcite
Collected by Hendy in 2014
Collection methods: surface (float),
• COLLECTOR: A. Hendy, 01/25/2014. REPOSITORY: Field observations and specimens reposited at Universidad del Norte, Colombia.
