Wali-Abad reef (Triassic of Iran)

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

• siliclastic-carbonate deposits

Size classes: macrofossils, mesofossils, microfossils

Preservation: recrystallized

Collection methods: peel or thin section

• Repository: Institute of Paleontology, Erlangen-Nürnberg University
