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• coordinate based on unpublished field data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: upper 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 unconformably overlain by the Castilletes Formation. This area and nearby collections have been previously mapped as Castilletes Formaton (late Pliocene-early Pleistocene). AGE: Burdigalian, on the basis of macrofaunal composition and stratigraphic position. STRATIGRAPHIC POSITION: From uppermost part of the Jimol Formation; from 64 m below Jimol/Castilletes contact.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; unlithified, shelly/skeletal siltstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite
