Barrenechea Creek (Pleistocene of Argentina)

Also known as Arroyo Barrenechea

Where: Entre Ríos, Argentina (32.1° S, 60.5° W: paleocoordinates 32.1° S, 60.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Salto Ander Egg Formation, Lujanian (0.8 - 0.0 Ma)

Environment/lithology: terrestrial; gravel

• The integrated stratigraphic col- umn is formed by: 1) poorly structured mud facies, which can be interpreted as aggradational deposits in a low energy flow regime, both proximal to and distal from the channel; 2) cross-stratified clast- supported conglomerate facies; 3) low-angle cross-bedded sandy gravels facies; 4) low-angle stratified sandy silt facies. Lithofacies 2, 3 and 4 correspond to channel facies of a braided river (Brunetto et al.,

•2015).

Size class: macrofossils
