RN02, Algorta Town (Cretaceous of Uruguay)

Where: Uruguay (32.5° S, 57.4° W: paleocoordinates 35.5° S, 44.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Queguay Formation, Maastrichtian (72.1 - 66.0 Ma)

• Some papers give a Paleogene age, but Late Cretaceous is more likely based on the abundance of sauropod eggshells. Veroslavsky et al. (2019) dated carbonates in the Queguay Formation at around 72 Ma.

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified limestone

• Pedogenic and palustrine carbonates

Size class: macrofossils
