A story on paleontology in Utah's big national monuments--Alan Titus's work in Grand Staircase-Escalante NM with possible implications for new Bears Ears NM. Twenty years as a NM, Grand Staircase-Escalante has yielded 12 named dinosaurs, 5 named marine reptiles, 15 species yet to be described, a possible new ecosystem for Laramidia during the Cretaceous, and current work on three tyrannosaurs. For Bears Ears NM the potential is for the continued discovery of earlier organisms (crocodiles, tetrapods), according to Rob Gray, including how life responded just after the Permian-Triassic extinction. Also, a sidebar on looting and destruction of fossil sites.
