Fieldwork is essential to make the new fossil discoveries that drive scientific research,  increasing our knowledge of Earth's history. New fossils also build the museum collection, providing the raw material for new exhibits.

Our fieldwork program is one of the largest in the region, spending an average of over six weeks in the field every year.

Currently, we are collecting dinosaurs from the Hell Creek and Judith River formations of Montana and North Dakota. These rock formations record the end of the Cretaceous Period, shortly before dinosaurs become extinct 66 million years ago in the K-Pg mass extinction.

The Judith River Formation was deposited ~79-76 million years ago. At this time, northern Montana was a vast floodplain with deltas and coal swamps reaching out into the shallow seaway that covered the Dakotas and what became the central United States.

Historically, very few good dinosaur skeletons have been collected the Judith River Formation, despite it having been studied for over 100 years. However, our fieldwork has identified many very promising sites, including what might be a very good articulated tyrannosaur skeleton, a mummified duckbill, and a bonebed of horned dinosaurs.

In summer 2018 we will be back out in the Judith River, intent on extracting some of these skeletons to bring back to the museum.

The Hell Creek Formation of Montana and the Dakotas was deposited ~67-66 million years ago, and records the last non-avian dinosaurs to have lived before the K-Pg mass extinction.

It is famous for dinosaurs such as Tyrannosaurus, Edmontosaurus and Triceratops, which are common fossils in the Hell Creek. We collect our fair share of these giants, but our fieldwork especially focuses on the less common dinosaurs, including rare species or young growth stages of larger species.

We currently work mainly in Montana, where we have important research sites, but would like to expand our operation into southwest North Dakota and will be exploring for some new localities in 2018.
