Cerro de los Leones, level 4 (Cretaceous of Argentina)

Where: Neuquén, Argentina (39.6° S, 69.4° W: paleocoordinates 43.7° S, 39.4° 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

• the Cullín Grande Member is regarded as early Albian in age (Leanza and Hugo, 1995; Leanza et al., 1997, 2001) based on its fossil content (at the type-locality) and the strati- graphic correlations with the Rayoso Formation of the center of the Neuquén Basin (Leanza, 2002).

• group of beds-level stratigraphic resolution

Environment/lithology: levee; fine-grained, medium, quartzose 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...level 4 consists of top bar and levee deposits"
• "medium to fine grained, quartzitic sandstones"

Size classes: macrofossils, mesofossils
