Where: New South Wales, Australia (34.2° S, 150.7° E)
• Paleocoordinates: 76.9° S, 108.7° E (Wright 2013)
• coordinate estimated from map
• small collection-level geographic resolution
When: Rouse Hill Siltstone Member (Ashfield Shale Formation), Anisian (247.2 - 242.0 Ma)
• Rouse Hill Siltstone is lowest member of the Ashfield Shale Formation, which is itself the basal formation in the Wianamatta Group (see Warren 2012: fig. 1). The Rouse Hill Siltstone overlies the Mittagong and Hawkesbury Sandstone formations. The Ashfield Shale has been asigned an Anisian age on the basis of palynomorphs (Aratrisporites parvispinosus Assemblage Zone) and plant macrofossils.
• bed-level stratigraphic resolution
Environment/lithology: marine; nodular, sideritic, black, gray, silty claystone
Size class: macrofossils
