Where: Colombia (3.3° N, 75.2° W: paleocoordinates 2.7° N, 72.6° W)
• coordinate estimated from map
• local area-level geographic resolution
When: La Victoria Formation (Honda Group), Laventan (13.8 - 11.8 Ma)
• "About 50 m stratigraphically above the Chunchullo Sandstone Beds"

•Note: This collection had a Friasian age but this must be the Friasian sensu lato, that includes the Friasian sensu stricto, Mayoan and Laventan. La Victoria formation is now considered of Laventan age (Flynn et al., 1997).
