Current park paleontologist Dan Chure has directed the monument's scientific programs since 1979. For more than twenty years, fossil preparators Jim Adams and Tobe Wilkins were almost as permanent a part of the quarry exhibit as the dinosaurs themselves as they worked to expose the fossil bones in place. During this period the only specimens to be removed from the quarry were those whose scientific importance warranted detailed examination, such as the baby Stegosaurus bones excavated in 1977. In recent years the focus of work has moved away from the cliff face and turned to other sites in the monument. Preparators may be seen on the cliff face during the busy summer months, but more often their work involves excavation and preparation of material from other Morrison sites. These may be other dinosaur sites, yielding important data not found at the main quarry, such as the recent discovery of an embryonic Camptosaurus; however, at least as important are new discoveries of other taxa such as frogs, salamanders, mammals, and plant fossils that give scientists a better understanding of the total Morrison ecosystem.
