Como Bluff in Carbon County and Albany County, Wyo., is the location of one of the world’s richest quarries of Jurassic dinosaur bones. Paleontologists found excellent dinosaur fossils in greater quantity here in the late 19th century than had ever been known before. These included Allosaurus, Diplodocus and Apatosaurus. Many of these specimens are still on display at the Peabody Museum at Yale University, the Smithsonian Institution’s National Museum of Natural History in Washington, D.C., and the American Museum of Natural History in New York City. The site is seldom quarried today, as most of the bones have been removed. Como Bluff is listed on the National Register of Historic Places.
