The Cretaceous in Georgia, US

Paleontology and geology

With sea level high throughout much of the Late Cretaceous, most of Georgia was under water, and shallow marine environments developed over its southern half. Sand from the eroding Appalachian Mountains in the north was carried by rivers southward into these waters, creating sandy and muddy shorelines in places. Large crocodiles and fish lived in the coastal environments, along with shellfish and burrowing shrimp. Dinosaurs roamed the upland environments, and their remains sometimes washed out to sea. This map indicates a band of Cretaceous rocks across the central part of the state.
