Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.2° N, 68.2° W)
• coordinate based on unpublished field data
• small collection-level geographic resolution
When: lower Castilletes Member (Castilletes Formation), Burdigalian to Burdigalian (20.4 - 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. AGE: Burdigalian-Langhian, on the basis of macrofaunal composition and stratigraphic position; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Likely in lower part of the Castilletes Fm, but in a faulted part of the sequence; from 49 m above Jimol/Castilletes contact.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; unlithified, shelly/skeletal siltstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite, original calcite
Collected by Hendy in 2011
Collection methods: bulk, surface (float), surface (in situ),
• COLLECTOR: A. Hendy, 03/07/2011. REPOSITORY: Presently reposited at Universidad del Norte, Colombia.
