Cerro de los Leones, level 3 (Cretaceous of Argentina)

Also known as Cerro León

Where: Neuquén, Argentina (39.6° S, 69.4° W: paleocoordinates 45.1° S, 41.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cullín Grande Member (Lohan Cura Formation), Albian (113.0 - 100.5 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

• "The sedimentary sequence of the Lohan Cura Formation was developed in a retro-arc foreland stage that began in the Early Albian as the result of Gondwanan break-up" "Thick sequence of meandering fluvial deposits...levels 2 and 3 are interpreted as flood basin deposits"
• "Thick variegated succession of mudstones with thin intercalations of fine-grained sandstone"

Size classes: macrofossils, mesofossils
