Where: La Guajira, Colombia (12.0° N, 71.3° W: paleocoordinates 11.2° N, 68.0° W)
• coordinate based on unpublished field data
• small collection-level geographic resolution
When: middle Jimol Member (Jimol Formation), Burdigalian (20.4 - 16.0 Ma)
• STRATIGRAPHIC RELATIONS: From the Jimol Formation, which conformably overlies the Uipta Formation (early Miocene) and is conformably overlain by the Castilletes Formation. AGE: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From a faulted area, but presumably in middle part of Jimol Formation; from approximately 100 m below Jimol/Castilletes Fm.
• bed-level stratigraphic resolution
Environment/lithology: offshore; poorly lithified mudstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite
Collected by Hendy in 2014
Collection methods: surface (float), surface (in situ),
