Also known as 98AD7A; Loc. 65
Where: Alaska (68.2° N, 162.9° W: paleocoordinates 32.9° N, 11.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Ikalukrok Member (Kuna Formation), Serpukhovian (330.9 - 323.2 Ma)
• STRATIGRAPHIC RELATIONS: From the Kuna Formation. AGE: early Late Mississippian (Meramecian to lower part of the Chesterian). Faunal group 1B of Holdsworth and Murchey (1988) and Assemblage Zone 4 (Scharfenbergia impella gp – Albaillella sp. aff. A. cartalla assemblage ) of Murchey (1990); placed here in the Serpukhovian to avoid stratigraphic orhaning. STRATIGRAPHIC POSITION: Ikalukrok unit of Kuna Formation; Suds prospect.
