Also known as STRI Sample 16870, 38480
Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.1° N, 68.1° 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• coordinate based on unpublished field data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. 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: Probably from the middle section of Jimol Formation, not far above Shirrua type section, probably somewhat higher stratigraphically than STRI 290414; from 120 m below the Jimol/Castilletes contact.
• bed-level stratigraphic resolution
Environment/lithology: transition zone or lower shoreface; poorly lithified, medium-grained, shelly/skeletal sandstone
Size classes: macrofossils, mesofossils
Preservation: original calcite, replaced with calcite
Collected by Hendy in 2011
Collection methods: surface (float), surface (in situ),
