Kolguyev Island (Cretaceous to of Russian Federation)
Where: Russian Federation (69.1° N, 49.3° E: paleocoordinates 60.8° N, 39.3° E)
• coordinate based on nearby landmark
When: Campanian to Campanian (83.6 - 66.0 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; graded, glauconitic, phosphatic, shelly/skeletal, gray, green, silty sandstone
• 25m wide and 5m high, at the bottom dark greenish gray and higher up light greenish gray glauconitic quartz silt, with fine-grained dense, indistinctly horizontally bedded sands having thing 1-2 cm stringers of shell detritus and Inoceramus with aa prismatic shell layer. The bottom 2m of these sands contain both small ( up to 6cm in diamerter) nospherical and slightly spherical phosphorite concretions without fossils, and also large spherical and ellipsoidal concertions up to 80 cm in diameter, consisting of very dense clacareous fine grained sandstones with numerous shell fragments of bivalves (including Inoceramus), gastropods, belemnite rostra and concretions of the first type. Above the lower 2-m series that is thoroughly filled with small and large concretions, the concretions decrease sharply and the sand gradually becomes lighter in color as they are interbedded with "khaki"-colored sands
Size class: macrofossils
Preservation: cast
