Barrancas del rio Carcaraña (Pleistocene of Argentina)

Also known as Carcarañá River, Espinillo natural reserve

Where: Sante Fé, Argentina (32.5° S, 60.8° W: paleocoordinates 32.5° S, 60.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Timbúes Formation, Lujanian (0.8 - 0.0 Ma)

• Vezzosi et al. 2019: In this work we assume that the well-defined fluvial deposits bearing the studied specimen correspond to the Timbúes Formation defined by Iriondo and Kröhling (2009), in the lower area of the Carcarañá River catchment. Despite not having geochronological data, the relative stratigraphic position of this lithostratigraphic unit, observed in several sections (Vezzosi, 2015) mainly on the Paraná River cliffs near Carcarañá River distal area (Timbúes and Campo de La Gloria sites, Fig. 1B), suggests that it was deposited during the Last Interglacial Stage.

• formation-level stratigraphic resolution

Environment/lithology: fluvial; lithology not reported

Size class: macrofossils
