Also known as Paraná Basin of State of Paraná
Where: Paraná, Brazil (25.5° S, 50.7° W: paleocoordinates 45.8° S, 29.7° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Irati Formation (Passa Dois Group), Artinskian (290.1 - 279.3 Ma)
• Rossmann & Maisch (1999) and Rossmann (2000, 2002) state that the fossils come from the Irati Formation but only give "Lower Permian" as the most precise age specification. However, in a quite 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).
• formation-level stratigraphic resolution
Environment/lithology: marine; limestone and shale
Size class: macrofossils
Preservation: mold/impression
Reposited in the BSP, SMF
