| 説明 | Seen here is the Morrison Formation, an Upper Jurassic succession that is widely distributed in many western American states. The Morrison consists of fluvial (river/floodplain) and lacustrine (lake) deposits, plus reddish-colored paleosol horizons. Dinosaur bones and dinosaur tracks are moderately common in Morrison Formation sediments. Exceptionally dinosaur-rich localities include Como Bluff in Wyoming, Dinosaur National Monument in Utah, Dinosaur Ridge in Colorado, and the Cleveland-Lloyd Quarry in Utah.Stratigraphy: Morrison Formation, Upper JurassicLocality: Escalante Petrified Forest State Park, northwest of the town of Escalante, central Garfield County, southern Utah, USA |
