~205 meter bed, Hutk section, 25 km north-northeast of Kerman (Carboniferous to of Iran)

Also known as Locality 5 of Webster et al. 2003.

Where: Kerman, Iran (30.6° N, 57.0° E: paleocoordinates 40.9° S, 68.3° E)

• coordinate stated in text

• local area-level geographic resolution

When: Siphonodella crenulata - Gnathodus typicus conodont zone, Bahram Formation, Hastarian to Hastarian (360.7 - 345.3 Ma)

• Fig. 2. Originally dated as Fammenian; Webster et al. (2003) note that this is actually Mississippian: "Conodonts from Locality 5, southeast of Hutk (upper horizon), yielded Protognathus praedelicatus Lane, Sandberg, and Ziegler 1980; Gnathodus typicus Cooper, 1939; Polygnathus communis communis (Branson and Mehl, 1934); and Clydagnathus cavusformis Rhodes, Austin, and Druce, 1969. This fauna suggests the horizon can be no older than S. isosticha-Upper crenulata Biozone because G. typicus first occurs within this biozone (Lane et al., 1980) and no younger than Scaliognathus anchoralis-latus Biozone. All three taxa are known to occur in this latter biozone." and "Conodonts from the crinoid-bearing beds represent two faunas and indicate an age of Upper Siphonodella crenulata Biozone to Gnathodus typicus Biozone."

• bed-level stratigraphic resolution

Environment/lithology: lithified, argillaceous limestone

• argillaceous limestone

Size class: macrofossils
