The Carnegie Quarry in northeastern Utah is world-renowned for the dinosaur skeletons it has produced and for its in situ display of dinosaur bones. The specimens excavated at Carnegie Quarry are displayed and curated in 20 repositories, most in North America. Data on these specimens in the forms of notes, photographs, publications, field maps, and so on, are scattered in an array of formats and institutions. The primary goal of this thesis is to develop a database linking these data with a digital map (GIS system) to make them readily accessible. To this end, a relational database was created using Microsoft Access linked to a vector-based map developed using Avenza MAPublisher running in Adobe Illustrator. Analyzing these data, the Carnegie Quarry produced 4146 specimens representing at least 105 individuals pertaining to 18 genera; 12 dinosaurs, one crocodylomorph, two turtles, Unio utahensis (a freshwater clam), and one plant. The map is based on high resolution photographs of the current quarry face merged with historic maps of previously excavated portions of the quarry. Previous attempts to develop a complete map were hindered by the large number of maps, primarily from four institutions that excavated at the site, and the lack of an accurate map of the current quarry face (due to substantial relief, the 67° dip of strata, and the lack of a permanent grid). The new maps will provide invaluable insights into the depositional setting, taphonomy and paleoecology of the site. The map and database provide a single access point for data on specimens from 20 widely dispersed repositories linking them their original quarry positions. This expandable tool will be invaluable to scientists and the caretakers of Dinosaur National Monument and is recommended for adoption at other quarries.
