Lithology and environment
Primary lithology:glauconitic,phosphatic sandstone
Includes fossils?Y
Lithology description: "Glauconitic-quartz sands, including beds and lenses of phosphorite nodules"
Environment:marine indet.
Geology comments: 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.
