Where: Iran (32.8° N, 49.6° E: paleocoordinates 23.6° S, 47.5° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Guadalupian (273.0 - 259.5 Ma)
• Little age information in the original paper and specimens not collected with stratigraphic context. Douglas reports "Fusulina limestones" being common at many localities (including Eopolydiexodina persica), suggesting a Guadalupian age, based on more recent biostratigraphy by Davydov & Arefifard (2013).
• group of beds-level stratigraphic resolution
Environment/lithology: lithified, black, carbonaceous limestone
Size class: macrofossils
Collection methods: Repository: Geological Survey of India
