The Pierre Shale, which consists of an upper sandy member and a lower shaly member, is primarily marine in origin; however, the sandy member includes minor amounts of coal. Located in southeast Montana and northwest Wyoming, the Powder River Basin is a region known for its rich coalbed methane potential - which currently supplies approximately 40% of the United States' coal. While overall coal interest has been in decline, the Powder River Basin remains a relatively active target for certain operators.Protostega is an extinct genus of turtle that lived in North America during the Late Cretaceous. Protostega is the second largest turtle that ever existed, being 3 meters (9.8 feet) long, only beat by Archelon and longer than Stupendemys. Protostega's shell lacked ossification, which helped bring the animal down in weight and streamline it for open …Sonnenberg, S.
