Also known as STRI Sample 17086
Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.2° N, 68.1° 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• coordinate based on unpublished field data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 conformably 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; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From the upper section of Jimol Formation; slightly higher in stratigraphy than STRI Loc. 290428, and lower than STRI 290602; from 52 m below Jimol/Castilletes contact.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; poorly lithified, shelly/skeletal siltstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite
Collected by Hendy in 2011
