STRI Loc. 290468 - Flor de Guajira Jimol Fm (Miocene of Colombia)

Where: La Guajira, Colombia (11.8° N, 71.4° W: paleocoordinates 11.1° N, 68.1° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: 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. 290427, and lower than STRI 290428; from 55 m below Jimol/Castilletes contact.

Environment/lithology: lagoonal; poorly lithified, shelly/skeletal siltstone

• ENVIRONMENT: Siliciclastic, lagoonal, normal salinity; 0-15 m.
• SPECIFIC LITHOLOGY: Poorly consolidated rusty silt matrix. LITHIFICATION: Poorly lithified, as determined in the field and based on museum-reposited specimens.

Size class: macrofossils

Preservation: original calcite

Collected by Carrillo-Briceno in 2013

Collection methods: surface (float), surface (in situ),

• REPOSITORY: Paleontological Institute and Museum, University of Zurich
