Also known as Paraná Basin
Where: Goiás, Brazil (17.3° S, 52.7° W: paleocoordinates 37.5° S, 27.7° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Assistencia Member (Irati Formation), Artinskian (290.1 - 279.3 Ma)
• The authors give a Sakmarian age of the Irati Formation referring to Pinto (1972) and Oelofsen & Araújo (1987). 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).
•The presence of limestones (see lithological description) indicates that the locality is within the Assistência Member of the Irati Formation (see Santos et al., 2009, J. S. Am. Earth Sci., Article in Press, doi:10.1016/j.jsames.2008.12.002)
• group of beds-level stratigraphic resolution
Environment/lithology: dolomitic, gray, white, yellow lime mudstone and dolomitic, white, yellow lime mudstone
Size class: macrofossils
Preservation: mold/impression
