Western Interior Cretaceous
Cretaceous North America was divided throughout most of the period by the Western Interior seaway, which connected temperate waters to the developing Arctic Ocean and tropical waters of the opening Atlantic. Vast quantities of terrigenous clastic sediments, fed into the seaway from the Cordillera, a...

Widely distributed, rapidly evolving, invertebrate stocks and a reliable radiometric time-scale combine to produce an exceptionally refined stratigraphic system.
