Where: Santa Cruz, Argentina (50.2° S, 69.7° W: paleocoordinates 50.8° S, 64.1° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Santa Cruz Formation, Santacrucian (17.5 - 16.3 Ma)

• Arnal et al 2019: Barrancas Blancas (BB; 17.21–16.3 Ma), with two sites, Estancia Aguada Grande (EAG) and Estancia Santa Lucía (ESL)

•Cuitino et al 2019 (focused on stratigraphy) tuff was dated in 17.04 ± 0.55 by means of U/Pb on zircons (Cuitiño et al., 2016), and it is used as a marker bed to correlate with Section EAG2 (Fig. 8)

•This tuff was dated in 17.04 ± 0.55 by means of U/Pb on zircons (Cuitiño et al., 2016), and it is used as a marker bed to correlate with Section EAG2 (Fig. 8). In this part of the SCF no terrestrial fossil vertebrates were recovered

• formation-level stratigraphic resolution

Environment/lithology: "floodplain"; lenticular, tabular, paleosol/pedogenic, silty sandstone

Size classes: macrofossils, mesofossils

Collected by C. Ameghino, Fernicola et al in 2013-2014
