Deep Time on the Grand Staircase: Dinosaurs, Discoveries & the Late Cretaceous of Southern Utah

  • Big Water Town Hall 26-60 Aaron Burr Big Water, UT, 84741 (map)

Big Water Dinosaur Festival keynote speaker, Christa Sadler, will present an in depth look at the rich prehistory of Grand Staircase-Escalante National Monument. Come to the Big Water Town Hall at 6:00pm (AZ time) for an inside look at over a million years of science in Southern Utah.

Deep Time on the Grand Staircase explores the extraordinary world of southern Utah during the last part of the Age of Dinosaurs. From about 100 million years ago to 76 million years ago, the region was home to a diversity of plants and animals that seems impossible today: magnolias and smothering vines, conifers and sycamores played host to a menagerie of dinosaurs and crocodiles, turtles and lizards—and early members of the birds and mammals. While most of these creatures and plants would become extinct at the end of the Cretaceous, at this point in time life was flourishing, and southern Utah appears to have been a cradle of diversity and evolution. Although we see the beginnings of our modern world in this time period, we also may be able to look into the future by examining the past. The extraordinary “greenhouse world” of the Late Cretaceous may have important information for our modern world in the context of a changing climate and changing ecosystems.

Christa Sadler was trained as a paleontologist at the University of California, Berkeley, and completed her master's degree in Earth Sciences at Northern Arizona University in Flagstaff. She has worked from the Pliocene to the Cambrian throughout the western United States and Mongolia.
