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)

Environment/lithology: reef, buildup or bioherm; lithified limestone
Size classes: macrofossils, mesofossils
