Earl Douglass was the paleontologist who discovered the Carnegie Quarry and supervised excavations for fifteen years.
Gilbert “Gil” Stucker was a fossil preparator in the Department of Vertebrate Paleontology for the American Museum of Natural History from 1957 to 1980, who contributed to preparation of the in situ exhibit at the Carnegie Quarry. In 1936, Gil was hired by the United States National Museum to prepare a skeleton of Camarasaurus from the Carnegie Quarry Greater Texas and Pan American Exhibition in Dallas. Gil was hired by paleontologist Ted White of Dinosaur National Monument as an instructor of fossil preparation. Gil trained long time preparators Jim Adams and Tobe Wilkins, who would later contribute to the majority of the reliefing work at the Carnegie Quarry.
