THE DINOSAURS OF WEST AMERICA: LIFE, DEATH, AND EVOLUTION ON AN ISLAND CONTINENT
Scott D. Sampson, Ph.D.
Utah Museum of Natural History and Department of Geology and Geophysics, University of Utah

For most of the Late Cretaceous, the Western Interior Seaway—a north-south oriented epeiric sea—divided North America into eastern and western landmasses, known formally as Laramidia (the western landmass) and Appalachia (its eastern counterpart). The isolation of Laramidia, here referred to informally as “West America,” persisted for approximately 30 million years, marooning its constituent biota for the great bulk of this duration. The Cordilleran Overthrust Belt formed a mountainous spine down most of the length of this narrow landmass. During the late Campanian (ca. 75 million years ago), the total combined area of terrestrial and freshwater habitats in West America was approximately one-fifth the present day size of North America, with seaway transgression-regression cycles periodically shrinking this value much further. The remains of West American dinosaurs have been recovered from virtually the full latitudinal span (Alaska to Mexico) and a significant portion of the stratigraphic range. Together, the dinosaur (and other vertebrate) faunas comprise the best documented, continent-scale evolutionary experiment for the entire Mesozoic, opening the door to large-scale studies of evolutionary patterns and processes. Results to date, many of them derived from recent work in Grand Staircase-Escalante National Monument, are exciting and surprising, suggesting that Mesozoic terrestrial ecosystems may have differed considerably from modern-day counterparts. This talk will explore our current knowledge of terrestrial ecosystems on West America—with a strong emphasis on dinosaur biology, ecology and evolution—and address possible avenues for future research.

 

Day 3 - Sunday, May 24, 2009 (all times MDT)

Field Trip

Late Cretaceous Depositional Systems and Paleontology of the southern Sevier Foreland Basin, south-central Utah.

Participants will travel from the Cedar Canyon area east of Cedar City to the central Kaiparowits Plateau, examining the thick and highly fossiliferous Late Cretaceous proximal foreland basin sequence deposited in response to the Sevier Orogeny. The timing of major depositional events, source areas, biostratigraphy and chronostratigraphy, vertebrate paleontology and general paleobiology for this portion of the basin, which contains one of the most complete Late Cretaceous terrestrial vertebrate faunal successions in the world, will be reviewed. Vans will depart promptly from the main entrance area of the Dixie Center (west side of complex) at 7:00 am and return at 9:00. A box lunch will be included in the fee. Dinner is not included but the trip will stop at Ruby’s Inn to eat.
