JURASSIC ERA

201.3 to 145 million years old (middle period of the Mesozoic Era)


The mixture of relatively young and well documented sandstone layers in Southern Utah makes the area a paradise for paleontologists and geologists who are able to explore a variety of fossils from the planet's geologic history.


The Morrison Formation is centered in Wyoming and Colorado, with outcrops in Montana, North Dakota, South Dakota, Nebraska, Kansas, the panhandles of Oklahoma and Texas, New Mexico, Arizona, Utah, and Idaho. Equivalent rocks under different names are found in Canada.[1] It covers an area of 1.5 million square km (600,000 square miles), although only a tiny fraction is exposed and accessible to geologists and paleontologists. Over 75% is still buried under the prairie to the east and much of the rest was destroyed by erosion as the Rocky Mountains rose to the west.
