Geography
| Country: | Russian Federation | State/province: | Khanty-Mansi Autonomous Okrug |
| Coordinates: | 62.5° North, 60.3° East (view map) | ||
| Paleocoordinates: | 58.5° North, 56.7° East | ||
| Basis of coordinate: | estimated from map | ||
| Geographic resolution: | outcrop |
Time
| Period: | Jurassic | Epoch: | Late/Upper Jurassic |
| Stage: | Kimmeridgian | 10 m.y. bin: | Jurassic 5 |
| Key time interval: | Late/Upper Kimmeridgian | Ammonoid zone: | Aulacostephanus autissiodorensis |
| Age range of interval: | 152.20000 - 149.20000 m.y. ago |
Stratigraphy
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 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. | |||||
Lithology and environment
| Primary lithology: | gray,blue lithified claystone |
| Lithology description: Gray bluish plastic clays. The bed contains flattened round concretions of gray clay limestone to 0.6 m across. | |
| Environment: | open shallow subtidal |
| Geology comments: The explored Kimmeridgian section denuded along the Lopsiya River formed under the embayment conditions of an epicontinental West Siberian sea, covering the territory of more than 2 mln km^2. This Lyapinsky Bay was rather shallow and opened toward the NNE. The narrow band of the Uralian Peninsula seperated it from the Timon-Pechora Sea in the west, and the small Berezovsky Archipelago seperated it from the West Siberian Sea in the east. | |
