Where: Colombia (3.2° N, 75.2° W: paleocoordinates 2.6° N, 72.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Baraya Member (Villavieja Formation), Laventan (13.8 - 11.0 Ma)

• Note: This collection had a Friasian age but this must be the Friasian sensu lato, that includes the Friasian sensu stricto, Mayoan and Laventan. The lower Villavieja formation (Baraya member) is considered of Laventan age now and the upper Villavieja formation is considered Laventan-Mayoan in age (Flynn et al., 1997).

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; green claystone and green mudstone

Size class: macrofossils

Collection methods: "Isolated mammal teeth and snake vertebrae are also abundant"
