Where: Isfahan, Iran (33.1° N, 52.0° E: paleocoordinates 29.4° N, 40.0° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Nayband Formation, Norian (228.0 - 208.5 Ma)

The unit of conglomerate at the base of the Lower Cretaceous contains pebbles of carbonate and siliciclastic rocks without any sign of the Jurassic fossils.

Environment/lithology: reef, buildup or bioherm; lithified limestone and lithified sandstone

Size classes: macrofossils, mesofossils
