Abstract

The Late Jurassic Morrison Formation is one of science's best windows into the world of dinosaurs and Mesozoic ecosystems. The Morrison Formation has significant exposures in many units within the Rocky Mountain Region of the National Park Service. These include Arches National Park (ARCH), Bighorn National Recreation Area (BIRO), Black Canyon of the Gunnison National Monument (BLCA), Capitol Reef National Park (CARE), Colorado National Monument (COLO), Curecanti National Recreation Area (CURE), Dinosaur National Monument (DINO), Glacier National Park (GLAC), Glen Canyon National Recreation Area (GLCA), Hovenweep National Monument (HOVE), and Yellowstone National Park (YELL). The Morrison Formation Extinct Ecosystems Project, hereafter called the Morrison Project, began on June 1 of 1994. The project is a multidisciplinary endeavor to determine the nature, distribution, and evolution of the ancient ecosystems that existed in the Western Interior of the United States during the Late Jurassic Epoch when the Morrison Formation and related rocks were deposited. The information obtained from the research can be used to suggest appropriate resource management actions and the project will also provide an improved understanding of the geological and paleontological history of these NPS units and better information for interpretive programs and publications.
