La Cuesta Azul (Paleocene of Argentina)

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

• coordinate stated in text

• outcrop-level geographic resolution

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

• Green shale facies in the middle part of the formation

• group of beds-level stratigraphic resolution

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

• "The MaĆ­z 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

Size classes: macrofossils, mesofossils

Preservation: mold/impression
