Morrison Formation

The Morrison Formation is a geological layer of sedimentary rock found primarily in the western United States, dating back to the late Jurassic period, about 150 million years ago. It is known for its rich fossil beds, which include dinosaur bones and footprints, and a variety of other prehistoric plants and animals. The formation provides significant insights into the ecology of that time, including the habitats of large dinosaurs like the Brachiosaurus and Stegosaurus. Its varied landscape once consisted of floodplains, rivers, and lakes, making it essential for understanding the evolution of life during the Jurassic era.
