Amazing Earthfest – Extreme Dinosaur Diversity on Laramidia’s Southern Frontier: New Discoveries from Utah’s Grand Staircase

May 11 @ 6:00 pm - 7:30 pm

Summary: During much of the Late Cretaceous, Laramidia, the western landmass of North America isolated by the Western Interior Seaway, hosted some of the most diverse dinosaur ecosystems ever uncovered. In addition to spectacular dinosaurs, these fossil assemblages include first appearances of many modern groups of plants and animals, including alligators, birds, and flowering plants, making the sequence and timing of their radiations consequential for understanding the origins of modern ecosystems. Recent work by the Denver Museum of Nature & Science and other collaborating institutions have uncovered troves of new fossils from central and southern locations on Laramidia, notably on the Kaiparowits Plateau of southern Utah in Grand Staircase-Escalante National Monument. A decade of fieldwork in the Kaiparowits and Wahweap formations has revealed new fossiliferous intervals hosting dozens of new dinosaurs, many of them challenging previous hypotheses of dinosaur distribution.

Brief bio:

GSEP Board member, Joe Sertich, is Curator of Dinosaurs at the Denver Museum of Nature & Science where his research focuses on Late Cretaceous dinosaurs and their ecosystems. His field-based work has taken him to many of the Gondwanan continents of the southern hemisphere, including multiple expeditions to Madagascar and Africa where he has worked on bizarre crocodiles and giant sauropod dinosaurs. Closer to home in the Rocky Mountain West, his research is focused on the ecology and evolution of dinosaurs during the last 20 million years of the Cretaceous. In addition to investigations into the latest-Cretaceous dinosaurs of Colorado, he leads the Laramidia Project, currently working to uncover dinosaur ecosystems in the Cretaceous of Grand Staircase-Escalante National Monument, Utah, northwestern New Mexico, and the Big Bend region of Texas.
