Prelude

The Late Paleozoic Era witnessed many significant geologic events, not the least of which was the assembly of the latest supercontinent, Pangea. The Appalachian Mountains of the eastern U.S.A. are the result of the collision between Laurentia (ancestral North America), Eurasia, Africa, and South America. The Ancestral Rockies formed in the western U.S. during this time as well. Many diverse depositional environments existed across this huge landmass and its broad continental shelves, including stream flood plains and deltas, desert sand dunes, playas, sabkhas, shallow marine areas, etc. Much of this history is also preserved in the upper part of the Grand Canyon in Arizona.
