About This Project
Grand Staircase Escalante Partners
Tyrannosaurs are essential components of Late Cretaceous ecosystems, but are generally rare and poorly known, especially in the southern U.S. We discovered a mass mortality site, including tyrannosaurs in multiple growth stages. What caused this mass mortality? How diverse were southern tyrannosaurs? What can we conclude regarding the social structure of these apex predators? Full excavation of the site and preparation of the fossil material will help us answer these critical questions.
