Cretaceous Western Interior Seaway
Around 90 mya, Cretaceous North America My home state of Minnesota was partially submerged during much of the Cretaceous, with the Eastern edge of the Western Interior Seaway running right through the state. Amazing to think that plesiosaurs, ammonites and exotic sharks may have been swimming right where I was sitting while I worked on these images!
Made for an exhibit at the Minnesota Discovery Center in Chisholm, and the Hill Annex Mine Paleontology Project.
