Where: Colombia (11.9° N, 71.3° W: paleocoordinates 11.1° N, 68.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Jimol Formation, Burdigalian to Burdigalian (20.4 - 13.8 Ma)

• STRATIGRAPHIC RELATIONS: Originally stated to be from the Castilletes Fm, but more recent mapping would place this in the Jimol Fm, which conformably overlies the Uipta Fm (early Miocene) and is overlain by the Castilletes Fm (late Pliocene-early Pleistocene. AGE: Burdigalian-Serravalian on the basis of macrofossil biostratigraphy and Sr isotope dating. STRATIGRAPHIC POSITION: From unknown position within stratigraphy.

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, calcareous sandstone

Size class: macrofossils

Preservation: cast, mold/impression, replaced with calcite
