Where: Pakistan (32.6° N, 71.8° E: paleocoordinates 42.3° S, 55.9° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Wuchiapingian to Wuchiapingian (259.9 - 252.2 Ma)
• Stratigraphic position unknown, Waagen speculates based on nature of matrix that specimen collected in Upper Productus Limestone (=Chhidru Fm, latest Wuchiapingian to Changhsingian). All other collections from Musakheyl area are also Lopingian in age.
• group of beds-level stratigraphic resolution
Environment/lithology: marine; lithified limestone
