Paleontologists dig for Jurassic dinosaur fossils

The Morrison Formation is one of the most famous dinosaur fossil sites in North America. Since the 1890s, it has been the site of discoveries such as Stegosaurus, Apatosaurus, and Allosaurus. But there’s more to be uncovered.

In 19th century, expeditions to the Morrison Foundation focused on the fossil remains of large animals, but today scientists are searching for fossils of species that were previously overlooked, especially in the relatively understudied northern portion. A team led by Museum paleontologist Mark Norell has returned year after year to uncover layers of the Jurassic. The results, both in the scale and quality of fossil discoveries, are exciting.
