Where: Colombia (3.3° N, 75.2° W: paleocoordinates 2.5° N, 72.0° W)

• coordinate estimated from map

• local area-level geographic resolution

When: La Victoria Formation (Honda Group), Friasian (16.3 - 15.5 Ma)

• "About 50 m stratigraphically above the Chunchullo Sandstone Beds"

• formation-level stratigraphic resolution

Environment/lithology: fluvial; pebbly, volcaniclastic, gray sandstone and ferruginous, shelly/skeletal, gray, green, red mudstone
