Where: Colombia (9.8° N, 75.2° W: paleocoordinates 7.2° N, 67.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Bartonian (41.3 - 38.0 Ma)

• STRATIGRAPHIC RELATIONS: From a unit referred to as the Carmen section of the Eocene, for which lithostratigraphic relations are unclear. AGE: Eocene, though not clear; age assignment reassigned based on the known biostratigraphic ranges of constituent taxa in more recent literature; here assigned to Bartonian (early Middle Eocene), but it is acknowledged that considerable constituent taxa have known age ranges extending (but not exclusive) to the Late Eocene and Ypresian. STRATIGRAPHIC POSITION: From Horizon F of the Carmen section.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, concretionary shale and lithified, concretionary sandstone

Size class: macrofossils
