Where: Pakistan (32.7° N, 71.8° E: paleocoordinates 39.1° S, 57.0° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Bivalve Beds Member (Upper Ceratite Limestone Formation), Spathian (251.3 - 247.2 Ma)
• A late Smithian age is indicated by the presence of Hedenstroemia and Xenoceltites between BB2 and BB3, whereas in BB7, a new genus of Tirolitidae that is morphologically transitional towards Columbites already postdates the earliest Spathian. In consequence, at Nammal, the Smithian–Spathian boundary is located above BB3 and below BB7.
• bed-level stratigraphic resolution
Environment/lithology: lithified limestone
Size class: macrofossils
