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
Collected by Thomas; reposited in the USNM
Collection methods: surface (in situ),
• COLLECTOR. D. Thomas, c. 1970. REPOSITORY: Not stated in text. Non-type specimens observed in USNM stratigraphic collections by A. Hendy (1/2011).
