El Fuerte (Paleocene of Argentina)

Where: Jujuy, Argentina (24.3° S, 64.5° W: paleocoordinates 27.1° S, 53.0° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Maz Gordo Formation, Late/Upper Paleocene (58.7 - 55.8 Ma)

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithified, green shale

• "The Maz Gordo Formation, related to the last main flooding event of the basin, shows typical lacustrine limestone values, possibly with low organic productivity"

•The lake which formed the Maiz Gordo formation must have been very shallow because it has alternating lacustrine and partially exposed mudflat deposits

• "green shales" (Petrulevicius and Nel 2007)

Size class: macrofossils

Preservation: mold/impression
