Sediments from the sea in the North American Continent that condense into a layer of rock known as shale or Mowry shale Thermopolis. Sediment is rich with oil and save fossil ancient beings.
Wind and water erosion that formed the unique geological forms of the Grand Staircase also open the shale layers. Paleontology experts who explore the wild region of 1.7 million Acre (687 hectares) to find fossil remains of plesiosaurus and other ancient marine life in the shale.
