Abstract
A high-resolution stratigraphic framework based on macrofossils, microfossils, regional marker beds, radiometric age determinations, inorganic geochemistry, and stable isotopic composition of carbonate and organic matter has been developed for the Upper Cretaceous Greenhorn and Niobrara formations, and equivalent units, in the US and Canada. Use of this framework has allowed characterization of cycles and events in paleoclimatic and paleoceanographic conditions that influenced sedimentation and early diagenesis of fine-grained carbonates in the Western Interior Seaway. -from Authors
