George Engelmann is a professor of Geology at the University of Nebraska at Omaha where he has been teaching and doing research in Vertebrate Paleontology since 1980. Research interests include the phylogeny of vertebrates, especially early mammals, paleoecology of vertebrate faunas and the taphonomy of vertebrate fossil occurrences. Since 1984, his research has focused on Mesozoic vertebrates and the paleontology and paleoecology of formations exposed around Dinosaur National Monument, most recently the Nugget Sandstone.

Dan Chure has been a dinosaur fanatic since seeing his first dinosaur movie at the age of three and the dinosaur halls at the American Museum of Natural History when he was five. Serving as the paleontologist at Dinosaur National Monument since 1979 his research interests include the phylogeny and paleoecology of Mesozoic tetrapods and terrestrial ecosystems, preservation and conservation of in-situ fossil exhibits, and fossil resource protection. Current research efforts are focusing on the paleontology and paleoenvironments of the Nugget Sandstone and the Digital Quarry Project, an interactive website covering the immense history, excavations, and research at the great Carnegie Quarry at Dinosaur.
