1 A geologic map of Utah, illustrates the strata conventionally colored differently according to geological age. Notice the San Rafael Swell, the dominant geologic and geographic feature in the eastcentral part of the State. The Cleveland-Lloyd Dinosaur Quarry (C-LDQ) is located on the northern end or nose of the Swell.P1048 James H. Madsen Photograph CollectionP1048n002
2 This view of the Cleveland-Lloyd Dinosaur Quarry (C-LDQ) in Emery County, Utah is typical of the primitive landscape and isolated areas, where many of Utah's dinosaurs are found and collected.P1048 James H. Madsen Photograph CollectionP1048n003
3 These colorful, Morrison Formation exposures are similar to the rock outcrops where dinosaur bones are found in many localities across the Colorado Plateau of Utah, New Mexico, and Colorado.P1048 James H. Madsen Photograph CollectionP1048n004
4 The Visitor Center at the C-LDQ, which became a United States Natural Landmark in 1968, has some interesting graphics that interpret and detail the operation and history of the Quarry. Included in the exhibits are some prepared, original dinosaur bones, and a mounted free- standing skeleton of a medium-sized Allosaur, which consists of less than 50% of the original, fossil bones. The skull of the Allosaur can be seen through the window in the front of the building.P1048 James H. Madsen Photograph CollectionP1048n006

6 This is a view of the main interpretive exhibit, an Allosaurus, inside the Visitor Center at the Cleveland-Lloyd Dinosaur Quarry. The Center is open on a limited basis during the summer months and not at all for the rest of the year. The Quarry, Visitor Center, and picnic areas are supervised and maintained by the United States, Department of the Interior, Bureau of Land Management with the support and excavation at various times of the College of Eastern Utah, Prehistoric Museum, the Earth Science Museum at Brigham Young University, and the Utah Museum of Natural History.P1048 James H.

7 This oil painting by Utah artist, Gale Hammond, is his interpretation of dinosaur life at the Cleveland-Lloyd Quarry 147.5 million years ago. A large Allosaur looks on, while a second predator attacks a Camptosaur. Notice the vegetation and a ponderous sauropod dinosaur wading the shallow lake in the background. Few dinosaur Paleontologists now agree that sauropods spent much time swimming or wading, thereby risking getting mired in the mud of or adjacent to shallow bodies of water.P1048 James H.

9 A good lesson to learn early on, when digging dinosaurs, is that even in a desert there is occasional rain; and when it rains, it is advisable to have a drain in the lowest part of the quarry excavation lest it turn into a wading pool, as seen here.P1048 James H. Madsen Photograph CollectionP1048n014
