Where: Paraguay (25.6° S, 56.8° W: paleocoordinates 41.5° S, 30.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Terezina Formation, Wordian (266.9 - 264.3 Ma)

• Presence of Pinzonella suggests a position in the Teresina Formation (Guerrini et al., 2019). Teresina Formation assigned to Wordian by Rocha-Campos et al. (2019) on the basis of radiometric dating.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified, fine-grained sandstone

Size class: macrofossils

Preservation: mold/impression
