1 This thin-section of bone from an Allosaurus radius shows a classic alternation of lamellated annuli and non-lamellated zones, confirming the presence of true zonal bone in Allosaurus. Photo and slide were prepared and described by Researcher, Dr. Robin Reid. Magnification X 100.P1048 James H. Madsen Photograph CollectionP1048n052

9 Quarry worker, indicating that he cannot find any fossils. Pot-holing is not a good quarrying procedure.P1048 James H. Madsen Photograph CollectionP1048nGS17
10 Prior to excavation the Quarry surface was carefully divided into a one yard grid system. Note the stakes and flags, which facilitated the precise mapping of each bone before its removal and transport to the laboratory at the University of Utah for preparation, curation, and eventual study.P1048 James H. Madsen Photograph CollectionP1048n016

16 This sacrum of a Camarasaur is in the collections of the Earth Science Museum at Brigham Young University. It exhibits the same tooth mark pattern as noted on a similar bone complex collected from the C-LDQ.P1048 James H. Madsen Photograph CollectionP1048n055
17 These students digging at the Quarry in 1976 are from Foothill Junior College near San Jose, California. They are learning first hand about the careful work required in collecting dinosaur bones. The Cleveland- Lloyd Dinosaur Quarry is often an important out-of-doors classroom for teaching the fundamentals of vertebrate paleontology and field collecting techniques.P1048 James H. Madsen Photograph CollectionP1048n036
18 During the 1960s at Fort Douglas, east of Salt Lake City, Utah was a World War II, army barracks, no longer standing on the upper University of Utah Campus, known as the "Bone Barn". It was the first "home" of the extensive bone inventory collected from the Cleveland-Lloyd Dinosaur Quarry. More than 60% of the original collection remained in Utah after the commitments to supporting institutions were met. These institutions had provided financial support for excavation, preparation, and research to the University of Utah Cooperative Dinosaur Project from 1960 to 1968. (June 1968)P1048 James H. Madsen Photograph CollectionP1048n040
19 This tooth of Allosaurus is representative of most theropods (carnivorous dinosaurs) in being sharply pointed and curved with serrate edges like the blade of a steak knife. These dinosaurs did not chew their food, but tore off large chunks of flesh and bone, which they swallowed whole. (May 1968)P1048 James H. Madsen Photograph CollectionP1048n049

25 Second, the more fragile and sometimes fractured fossil bones must be enclosed in a burlap and plaster jacket; which like the shell of an egg protects the contents so that each unit can be safely transported to the laboratory for final preparation and study. (June 1961)P1048 James H. Madsen Photograph CollectionP1048n024
