STRI Loc. 290679 - N of Puerto Lopez [middle Castilletes Fm] (Miocene of Colombia)

Where: La Guajira, Colombia (12.0° N, 71.3° W: paleocoordinates 11.4° N, 68.5° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: middle Castilletes Member (Castilletes Formation), Langhian (16.0 - 13.8 Ma)

• STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. AGE: Langhian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Probably from middle member of Castilletes Fm; immediately underlying Ware Fm; from an estimated 168 m above Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; unlithified siltstone

• ENVIRONMENT: Very shallow marine, probably slightly reduced salinity.
• SPECIFIC LITHOLOGY: Unconsolidated silty matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original calcite, replaced with calcite

Collected by Hendy in 2014

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