Villa El Chocón, 5 km southwest (Cretaceous of Argentina)

Also known as Araripesuchus patagonicus type locality

Where: Neuquén, Argentina (39.1° S, 68.6° W: paleocoordinates 46.2° S, 44.8° W)

• coordinate based on nearby landmark

When: Candeleros Formation (Neuquén Group), Early/Lower Cenomanian (99.6 - 93.5 Ma)

• Lower section of Candeleros Fm., Río Limay Subgroup

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; fine-grained, medium, dolomitic, intraclastic sandstone

• Sedimentological studies of Recent lake Ezequiel Ramos Mexia show that the area is a depositional fluvial environment crossed by an association of shallow water bodies, some of them relatively wide, subjected to a regime of sporadic seasonal flooding. The climate was temperate with alternate rainy and dry periods
• Ferruginous sandstone matrix. The rock is a medium-to fine-grained sandstone with pelitic intraclasts in tabular bodies

Size class: macrofossils
