110 The most demanding step in the study of dinosaurs takes place in the preparation laboratory, where a single bone may require more than a hundred hours of intense work before it can be analyzed in detail.Image
111 Most fossil bones are fractured, so must be coated with a preservative, as soon as they are uncovered and allowed to dry, to seal the fossil and fasten the numerous, tiny fragments in place. This step is necessary before the fossils can be safely removed and transported to the laboratory for final preparation and study.Image
112 Much of the necessary preparation of fossil bones, as demonstrated on this premaxilla of Allosaurus, is done with a miniature air hammer called an AirScribe. The AirScribe is an indispensable tool in the careful preparation of most dinosaur bones.Image
113 The neck, ribs, chevrons, and forearms are fastened in place as one of the final steps in the assembly.Image
114 Neural spine, sauropod (?), enclosed in the softer shale unit.Image
115 Next in the order of assembly, the dorsal (back) and caudal (tail) sections are attached to keep the mount in balance. (October 1988)Image
116 Next the legs are fastened to the mounting deck of the exhibit.Image
117 Northerly view of quarry from Visitor Center.Image
118 Notice the banded structure of this thin slice of fossilized bone. Studies are being made to determine the significance of the individual layers; which, if representing annulations or yearly growth rings, as seen in trees, might permit paleontologists to ascertain the age of an individual dinosaur. (May 1968)Image
119 On this Land-Sat photo of the State of Utah, heavily vegetated areas are red, unvegetated areas are light colored, and bodies of water are dark blue. Notice three prominent landforms: Great Salt Lake, the east-west aligned Uinta Mountains in the northeast corner of the state, and the San Rafael Swell in the eastcentral area. (May 1984)Image

125 The premaxillae of Marshosaurus to the left, and Stokesosaurus above, each with four teeth are compared with one of a very small Allosaurus to the right, which has alveoli for five teeth. Although all three of these dinosaurs were carnivorous, notice the difference in the shape of the tooth bearing bones. Similarly, if the teeth of each were present, they could be easily identified, one from another. (April 1972)Image
