Welcome to the Colorado Scientific Society

The oldest scientific society in the Rocky Mountain region

Founded in 1882, the Colorado Scientific Society promotes knowledge, the understanding of science, and its application to human needs, focusing primarily on earth science, but welcoming members with interests in all fields of science. Learn more.

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: 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.

March for Science, April 14, and Vote for Science

The Colorado Scientific Society is planning to take part in the March for Science in downtown Denver again this year on April 14, 2018. We will have a table at the Denver Civic Center again. Please plan to join us.

The March for Science organization also has a Vote For Science initiative to try to bridge the gap between advocating for science and civic engagement.  If you are interested in getting more information on this initiative and ways to educate your community and your representatives on why science and science policy matter, please go to this website:

Abstracts of Past Colo. Scientific Society Meetings

The Colorado Scientific Society was founded in 1882 as a forum for the exchange of observations and ideas on the topics of earth science. Our lecture series occurs on the third Thursday of each month, from September through May. Lecture topics largely focus on earth science, and are open to the public. In addition to our monthly lecture series, the society is also active in public service. We fund student research grants, construct and post signs that describe local geologic features, and organize and lead several field trips.

The Colorado Scientific Society usually meets on the third Thursday of the month from September through May at The Shepherd of the Hills Presbyterian Church, 11500 W. 20th Ave., Lakewood CO
Social time is at 6:30; meeting & program at 7:00
(In the summer months of June-August, too many are off in the field.)
