Where: Ceará, Brazil (7.7° S, 39.3° W: paleocoordinates 32.5° S, 8.7° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Irati Formation (Passa Dois Group), Artinskian (290.1 - 279.3 Ma)

• Rossmann & Maisch (1999) state that the fossils come from the Irati Formation but only give "Lower Permian" as the most precise age specification. However, in a fairly recent publication it is stated that the Irati Formation is Artinskian in age, based on absolute ages obtained from zircons from a bentonite layer (Santos et al., 2006, Gondwana Res. 9).

• bed-level stratigraphic resolution

Environment/lithology: limestone

Size class: macrofossils
