The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the The Cretaceous System in the western interior of North America American Inland Sea, and the Western Interior Sea) was a large inland sea that existed during the mid- to late Cretaceous period as well as the very early Paleogene, splitting the continent of North America into two landmasses, Laramidia to the west and Appalachia to the east.

The Western Interior Cretaceous Basin of North America evolved as a complex foreland basin between Late Jurassic and Cretaceous time in response to accelerated plate spreading, convergence, and subduction along the western margin of North America.
Sometimes, particularly during the mid-Cretaceous, conditions extended to epicontinental seas, as attested by deposits of black shales in the western interior of North America.
The Cretaceous world had three distinct geographic subdivisions: the northern boreal, the southern boreal, and the Tethyan region. Introduction The Western Interior Seaway, the large inland sea that covered much of North America during Late Cretaceous times, was one of the most extensive of the Late Cretaceous epicontinental seaways.
From Late Albian to Maastrichtian time it extended from the present-day Arctic Ocean to the Gulf of Mexico. Alencaster, G., and Pantoja-Alor, J.,The rudist Amphitriscoelus (Bivalvia—Hippuritacea) in the lower Cretaceous of southwestern Mexico, J.

The major physical events that altered life during and at the end of Cretaceous include continued rifting of the former Pangaea, very high sea levels, and some orogenic events, particularly the Sevier orogeny of western North America.
The physical separation of parts of Pangaea separated the animal and plant groups that lived there. Hattin, D.

At its widest, the Western Interior Seaway stretched across central Cretaceous North America from the Rockies in the west to the Appalachians in the east, a distance of approximately km ( miles). Fossils of many of North America's most famous dinosaurs have been found in the rocks of the Hell Creek Formation in Montana.

The relatively short duration of kimberlite magmatism in the mid‐Cretaceous corridor contrasts with the typically longer periods of magmatism recorded by other kimberlite fields in western North America, e.g., Late Cretaceous (88–68 Ma) kimberlites from the Buffalo Head Hills, Alberta [Eccles et al., ], or Late Cretaceous to Paleogene.

A synthesis of Late Cretaceous paleogeography of the Western Interior from Mexico to southwestern Canada emphasizes the areal distribution of peat-forming environments during six biostratigraphically constrained time intervals.

Conclusions. An update on the palynostratigraphy of the Dakota Formation is presented, identifying four distinctive Albian-Cenomanian palynostratigraphic zones in the areas of Iowa, Nebraska, and Kansas.

The ancient sea stretched from the Gulf of Mexico and through the middle of the modern-day countries of the United States and Canada, meeting with the Arctic Ocean to the north. centre of the Western Interior Cretaceous province of North America.

These are non marine terrestrial formations. There's lots of Cretaceous stratigraphy in western N. America but its mostly marine. On a quirkier note, when we are talking geology at the GSC we dont consider the west coast as North America. Of couse it.

The Cretaceous Period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic Period (i.e.
from ± million years ago (Ma)) to the beginning of the Paleocene epoch of the Tertiary Period (about ± Ma). As the longest geological Period, the Cretaceous constitutes nearly half of the Mesozoic. The end of the Cretaceous defines the boundary. Plesiosaur extinction cycles - events that mark the beginning, middle and end of the Cretaceous.

A new genus and species with affinities to Ceratophyllaceae from the Lower Cretaceous of Kansas, USA is reported. The fruits of Donlesia dakotensis gen. et sp. nov. are smooth achenes with two winged lateral spines, two winged facial spines, one stylar spine, and a long peduncle with a distinctive groove.
The facial spines are arranged perpendicular to the lateral spines.
