1 The "Cliff Skull" of Camarasaurus at Dinosaur National Monument is an important part of a comprehensive head skeleton study of this interesting Morrison Formation sauropod. One of several scientific papers now being prepared for publication by dinosaur paleontologists currently studying Utah dinosaurs.uum_mapImage
2 A caudal vertebra (tail bone) of the sauropod dinosaur, Camarasaurus, as found in place at the Quarry. This particular dinosaur would have been about 55 feet long, almost 12 feet tall at the hips, and perhaps weighing more than fifteen tons in life. An original skeleton of this huge reptile is exhibited in a death pose at the College of Eastern Utah, Prehistoric Museum in the city of Price, Utah. (July 1961)1961-07uum_mapImage

4 A death pose of an original, composite skeleton of Camarasaurus and Stegosaurus from the C-LDQ may be seen at the College of Eastern Utah Prehistoric Museum in the city of Price, Utah. Two skeletons at CEUPM are mounted in a huge sandbox, an inexpensive exhibit, which allows easy access to the individual fossil bones for research or study.1960; 1961; 1962; 1963; 1964; 1965; 1966; 1967; 1968; 1969; 1970; 1971; 1972; 1973; 1974; 1975; 1976; 1977; 1978; 1979uum_mapImage
5 A femur (thigh bone) of a Camarasaur illustrates the enormous size of this reptile. This bone, like most of the others in the Quarry, was found isolated rather than in close proximity to adjacent bones as they would appear with a complete, articulated skeleton. (July 1961)1961-07uum_mapImage

9 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.uum_mapImage
10 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.1970; 1971; 1972; 1973; 1974; 1975; 1976; 1977; 1978; 1979; 1980; 1981; 1982; 1983; 1984; 1985; 1986; 1987; 1988; 1989uum_mapImage
11 A large house trailer, seriously damaged traveling the rough road to the C-LDQ, was the solution to the housing problem the second year (1961) of the University of Utah Cooperative Dinosaur Project (UUCDP). (June 1961)1961-06uum_mapImage
12 A life-like reconstruction (Trophy Mount) by David Thomas of the head and shoulders of Allosaurus was prepared over a welded armature supporting exact casts of the original bones. The muscles, then the skin, were sculpted in turn to achieve a very life-like representation.1960; 1961; 1962; 1963; 1964; 1965; 1966; 1967; 1968; 1969; 1970; 1971; 1972; 1973; 1974; 1975; 1976; 1977; 1978; 1979uum_mapImage
