Duke Locality 59 (La Venta Fauna) (Miocene of Colombia)

Also known as IGM 183499

Where: Colombia (3.2° N, 75.2° W)

• Paleocoordinates: 4.0° N, 71.6° W (Wright 2013)

• coordinate estimated from map

• local area-level geographic resolution

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

• A stratigraphic level just below the Fish Bed, Villavieja Formation, Honda Group

•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: fluvial; red mudstone and red, yellow sandstone

• "The Villavieja Formation consists mainly of red mudstone alternating vertically and laterally with medium- to fine-grained, reddish-yellow sandstone; fining upward sequences are a common feature. In a minor proportion there are gray-greenish mudstones interlayered with gray, "salt and pepper," pebbly, medium- to fine-grained volcanic litharenites in fining-upward sequences"

Size class: macrofossils

Collection methods: Partial dorsal carapace with six movable bands, one semimovable, and 9 fixed bands from the pelvic shield
