Also known as Reef 83
Where: Iran (31.0° N, 53.0° E: paleocoordinates 2.4° N, 40.9° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Nayband Formation, Sevatian (212.0 - 205.6 Ma)
• Norian to Rhaetian age stated in text; according to Marcoux 1993 Nayband formation of Late Norian age. Conodonts and ammonoids below sponge-bearing beds are Norian. Kristan-Tollmann et al. (1979) considered the Oxycolpella beds (equivalent to the sponge beds) to be Rhaetian, followed by Schafer et al. (2003).
• group of beds-level stratigraphic resolution
Environment/lithology: reef, buildup or bioherm; lithified reef rocks
Size classes: macrofossils, mesofossils, microfossils
Preservation: recrystallized
Collection methods: peel or thin section
• Repository: Institute of Paleontology, Erlangen-Nürnberg University
