Stoilo Quarry, Staryi Oskol (Cretaceous to of Russian Federation)

Also known as Stoilen

Where: Belgorod, Russian Federation (51.3° N, 37.8° E: paleocoordinates 42.7° N, 32.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Albian to Late/Upper Albian (105.3 - 93.9 Ma)

• found in loose quarry deposits

• group of beds-level stratigraphic resolution

Environment/lithology: marine; glauconitic, phosphatic sandstone

• Marine vertebrates inhabitited this bay of the Tethys Ocean, which formed a deep inlet from the Southeast and possessed high bioproductivity due to wind upwelling. Dinosaurs inhabited the coastal sandy and forest areas with some areas forming mangrove environments. This area, Fenno-Sarmatia, eventually separated from Asia by a longitudinal strait. The hadrosaurs possibly migrated to western Europe from this landmass.

• "Glauconitic-quartz sands, including beds and lenses of phosphorite nodules"

Size class: mesofossils

Collected in 1994-1998

Collection methods: salvage, surface (float),
