Also known as "Arsiteneia", Rio Claro, Paraná Basin
Where: São Paulo, Brazil (22.5° S, 47.6° W: paleocoordinates 44.1° S, 24.4° W)
• coordinate based on nearby landmark
• hand sample-level geographic resolution
When: Assistencia Member (Irati Formation), 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). Preservation in limestone suggests that the fossil comes from the Assistência Member of the Irati Fm. (see Santos et al., 2009, J. S. Am. Earth Sci., Article in Press, doi:10.1016/j.jsames.2008.12.002).
