Where: Colombia (3.2° N, 75.2° W: paleocoordinates 2.6° N, 72.6° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Cerro Colorado 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 Cardon Red beds have been dated as 12.2-12.5Ma aprox. (Flynn et al., 1997). this makes them Laventan in age.
•
•The Honda Group is constrained by radiometric and paleomagnetic evidence to between approximately 13.5 Ma–11.8 Ma (Flynn et al., 1996; Guerrero, 1996; Madden et al., 1996).
• group of beds-level stratigraphic resolution
Environment/lithology: fluvial; red, silty claystone and mudstone
Size class: macrofossils
