1 The last attempt at housing the C-LDQ field crew was a 16 foot square shack that boasted a gas stove and refrigerator, a table, four chairs, and two folding cots. (June 1962)P1048 James H. Madsen Photograph CollectionP1048n011
2 Some fossil bones from the C-LDQ, such as this left premaxilla of Allosaurus, require minimal or no special preparation in the laboratory, but such is the exception rather than the rule.P1048 James H. Madsen Photograph CollectionP1048n019
3 These are fossil bones as discovered and uncovered in place at the Quarry. To one side are some of the tools used by the paleontologists who collect the fossils.P1048 James H. Madsen Photograph CollectionP1048n022a
4 This section of the composite Cleveland-Lloyd Quarry map illustrates the jumbled condition of bones, as they were at the time of burial. They appear as though the disarticulated parts of nearly six dozen dinosaurs had been stirred into a huge pot of mud and left to be found, unscrambled, and described by vertebrate paleontologists 147 million years later. Accurate maps and carefully written records are an essential part of dinosaur collecting and subsequent scientific research.P1048 James H. Madsen Photograph CollectionP1048n021
5 Tools and supplies commonly used here are: ice-pick, brush,screwdriver, bayonet, broom, trowel, knee pads, scoop, glue, sample bags, insect spray, boxes, and tissue paper. Minimal preparation is done to facilitate collection in the field, but the careful, finish preparation on each bone is done only after the fossils have been carefully transported to the laboratory.P1048 James H. Madsen Photograph CollectionP1048n022b
6 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.P1048 James H. Madsen Photograph CollectionP1048n058
7 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.P1048 James H. Madsen Photograph CollectionP1048n086
8 A full scale model of Maiasaurus, the "Good Mother Dinosaur", by artist Dave Thomas, was commissioned by the Museum of the Rockies in Bozeman, MT.P1048 James H. Madsen Photograph CollectionP1048n079
9 A full scale model of this life-like Allosaurus may now be seen in one of Utah's Museums. This 1:24 bronze scale model and the life-size replica were done by sculptor, David Thomas.P1048 James H. Madsen Photograph CollectionP1048n075
10 A full scale Pentaceratops is the companion bronze statue to Albertosaurus at the entrance of the New Mexico Museum of Natural History in Albuquerque. Pentaceratops is known from the Cretaceous formations of Alberta, Canada and New Mexico.P1048 James H. Madsen Photograph CollectionP1048n077
11 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.P1048 James H. Madsen Photograph CollectionP1048n074
12 A medial view of the premaxillae of a Marshosaur (left) with 4 teeth and Allosaur (right) with 5 teeth. These are important, taxonomic differences.P1048 James H. Madsen Photograph CollectionP1048n067
13 A poster attesting to the popularity of traveling dinosaur exhibits in Japan. The three digits on the manus suggest Allosaurus as the subject.P1048 James H. Madsen Photograph CollectionP1048n082
14 After working tirelessly for several hours, the crew exposes a Camarasaur rib.P1048 James H. Madsen Photograph CollectionP1048nQBD16

17 Allosaurus femur in cross section showing laminar bone (black) and calcite filled marrow cavity (white).P1048 James H. Madsen Photograph CollectionP1048nRES18
18 An unusually complete skull of a very large allosaur, originally collected at Dinosaur National Monument, is being prepared there by senior laboratory technician, Tobe Wilkens. There is cooperation and an ongoing exchange of ideas among the keepers and students of Utah's dinosaurs.P1048 James H. Madsen Photograph CollectionP1048n057
19 Another impressive, full-scale, life-like reproduction of a Morrison Formation dinosaur is the fiberglass model of Stegosaurus at Dinosaur National Monument near Jensen, Utah. The breathtaking Quarry exhibits of fossil bones exposed there are world famous and dinosaur paleontologists and tourists come from almost every country to see them.P1048 James H. Madsen Photograph CollectionP1048n071
20 Anterior teeth of Ceratosaurus, premaxilla, Dinosaur National Monument specimen.P1048 James H. Madsen Photograph CollectionP1048nRES07
21 As many shutters click, Senator Moss goes for the ribbon with big scissors.P1048 James H. Madsen Photograph CollectionP1048nQBD07
22 Bob Randolph explains the hardships of Quarry life.P1048 James H. Madsen Photograph CollectionP1048nQBD15
23 Cast replicas are carefully made of each original bone to be displayed in this museum exhibit, which is seen here under preparation. Utilization of molds and casts allows the original bones to be completely accessible for study and unharmed by the drilling often needed to present them in a free-standing, mounted skeleton.P1048 James H. Madsen Photograph CollectionP1048n046
24 The cast skeleton of Diplodocus carnegii guarded the Dinosaur Garden at the Utah Fieldhouse of Natural History State Park in Vernal for nearly three decades. It was taken down, remodeled, and remolded in 1989. Now a new mount has been presented inside the UFNHSP.P1048 James H. Madsen Photograph CollectionP1048n085
