Where: Neuquén, Argentina (39.6° S, 69.4° W: paleocoordinates 45.4° S, 41.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cullín Grande Member (Lohan Cura Formation), Early/Lower Albian (112.0 - 109.0 Ma)

• The Cullín Grande Member is the upper part of the Lohan Cura Formation

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; mudstone and fine-grained sandstone

• "Thick variegated succession of mudstones with thin intercalations of fine-grained sandstone"

Size classes: macrofossils, mesofossils
