Thursday, April 12, 2018 – Past Presidents’ Dinner

Colorado’s Exciting New Dinosaurs

includes the new Thornton discovery
Joe Sertich, Denver Museum of Nature and Science

This is an evening to honor the Past Presidents of our Society, to show appreciation for all our members, and to enjoy an evening together with friends, old and new, and colleagues. ALL CSS members and their family and friends are invited to come.

Hell Creek Formation, Late Cretaceous to Early Paleocene, ~66.8-66 Ma (Maastrichtian to Danian); claystone, mudstone, sandstone; Dakotas, Montana, and Wyoming

Abstract: The rich geology of Colorado captures nearly the entire evolutionary history of dinosaurs, ranging from their first appearance in the Triassic 240 million years ago to the last dinosaurs of the Cretaceous 66 million years ago. Included are the Rocky Mountain West’s iconic Jurassic dinosaurs like Stegosaurus and Allosaurus, so abundant in Colorado quarries they became a target of the late 1800’s “Bone Wars.” Cretaceous fossils preserved across Colorado capture the height of dinosaur evolution on “Laramidia” in addition to subtropical landscapes inhabited by the last dinosaurs to walk North America, the iconic Tyrannosaurus rex and Triceratops. New discoveries from the Front Range, like the spectacular ‘Thornton Torosaurus,’ promise to solve recent dinosaur mysteries and have ignited a dinosaur renaissance in Denver, the only major metropolitan area where dinosaurs still lurk in backyards.

Fruitland Formation, Late Cretaceous, ~75.5-74.5 Ma (Campanian); sandstone, shale, coal; San Juan Basin, New Mexico and Colorado.
Joe Sertich

Biography (from 2016): Joe Sertich is Curator of Dinosaurs at the Denver Museum of Nature & Science. He received his B.S. in from Colorado State University in 2004, his M.S. at the University of Utah in 2006, and his Ph.D. from Stony Brook University in 2011. His research focuses on dinosaurs, crocodiles, and flying reptiles, and their ecosystems, during the Late Cretaceous. His field-based research is split between the Gondwanan continents of the southern hemisphere and western North America. He is one of the primary researchers on the Madagascar Paleontology Project exploring the latest Cretaceous of Madagascar and has expanded the search for dinosaurs to older deposits across the island. He is also working on several projects searching for the first latest Cretaceous dinosaurs of Africa, including work in northern Kenya and Egypt. In North America, he leads the Laramidia Project, currently leading work to uncover a lost world of dinosaurs in the Cretaceous of Grand Staircase-Escalante National Monument, Utah, northwestern New Mexico, and northwestern Colorado.


Emmons Lecture

Tuesday, May 8, 2018

High Drama at the Paleocene/Eocene Boundary

Climate and Biology, Perspectives from the Paleocene/Eocene Thermal Maximum (PETM) in the Bighorn Basin; Implications for Today
Will Clyde, University of New Hampshire
On the Colorado School of Mines campus

Will Clyde, University of New Hampshire

The S.F. Emmons Lecture, which began in 1962, is a highlight of the Colorado Scientific Society’s activities and contributes not only to our standing in the scientific community but to the intellectual growth of our members and colleagues. The series is named in honor of the Society’s founder, S.F. Emmons. The lectures feature speakers that are recognized nationally or internationally as being at the forefront of research in some important facet of the earth sciences.
