Duke Locality 113 (La Venta Fauna) (Miocene of Colombia)

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).

• group of beds-level stratigraphic resolution

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

• The La Victoria Formation has "coarse- to fine-grained pebbly lithic arenites with important amounts of volcanic fragments and plagioclase alternating vertically and laterally with reddish-brown and greenish-gray mudstone. The mudstones are very rich in fossil vertebrates"

Size class: macrofossils
