Louisiana's fossil record begins in the Late Cretaceous Epoch and documents the presence of sharks and marine invertebrates. After the Cretaceous ended and the Age of Mammals began Louisiana would see local sea levels rise and fall. During submersions Louisiana was home to a diverse marine invertebrate fauna and the early whale Basilosaurus ...
The map of North America with the Western Interior Seaway during the Campanian. The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, or the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years.

"But here is an animal, probably some kind of fish, that 66 million years ago ate sea lilies that lived at the bottom of the Cretaceous sea and regurgitated the skeletal parts."
A clump of sea lily fragments from at least two different species of sea lilies, eaten during the Cretaceous period, now a piece of fossilised vomit. ... “This find is a unique glimpse into the ...
The current sedimentary basin results from the filling of a Cretaceous tectonic basin and existed as a large bay in the Cretaceous through early Cenozoic shoreline. The New Madrid Seismic Zone lies at the northern end of the embayment. It was the site of the large New Madrid earthquakes of 1811-12. The area is underlain by some anomalous geology.
He then brought his find to a museum where it was cleaned and examined by Dutch sea lily expert John Jagt. Researchers dated the fossil animal regurgitate to the end of the Cretaceous era nearly ...
The Door Point Volcano is a buried extinct volcano off the shore of St. Bernard Parish, Louisiana. It last erupted in the late Cretaceous period, between 74 and 90 million years ago. It was discovered in a drill core at approximately 8000' depth beneath the sea floor. The volcano is a sill composed of layers of volcanic ash and breccia.
