Also known as Bed 13; Bed 8 of Zakharov et al. 2005
Where: Khanty-Mansi Autonomous Okrug, Russian Federation (62.5° N, 60.3° E: paleocoordinates 58.5° N, 56.7° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Aulacostephanus autissiodorensis ammonoid zone, Late/Upper Kimmeridgian (155.7 - 150.8 Ma)
• Kimmeridgian Stage, Upper Substage, Aulacostephanus autissiodorensis Zone, Virgataxioceras dividuum Subzone (upper 1.5 m); thickness: 2.5 m. Zakharov et al. use the faunal lists from Mesezhnikov (1984) and the two sections correspond up to bed 7; after that Zakharov et al. skip or combine Mesezhnikov's beds so Zakharov et al.'s scale is offset by one.
• bed-level stratigraphic resolution
Environment/lithology: open shallow subtidal; lithified, gray, blue claystone
Size class: macrofossils
Collection methods: Repository: VNIGRI
