1 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)P1048 James H. Madsen Photograph CollectionP1048n066

4 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
5 Prior to mapping, each bone is carefully identified as to taxa (scientific name) and morphology (elemental name).P1048 James H. Madsen Photograph CollectionP1048n034

9 Rarely, tiny dinosaur tracks, such as these, are recovered from the coal mines of Carbon and Emery Counties in east-central Utah. Dinosaur bones are usually found in one area or formation and tracks in another, but rarely are the two ever found together. Tridactyl (three-toed) tracks have been found in the rocky ledges above the C-LDQ horizon, but they were not in association with any fossil bones as found in the Quarry. One expert supposes that these tracks were made by a Stegosaur.P1048 James H. Madsen Photograph CollectionP1048n069

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.
