Our experts at work


Much of the Perot Museum’s current research is based upon material collected during expeditions in Alaska (photos), from north of the Arctic Circle on the Colville River, to areas further south in Denali National Park. This work is part of joint programs among the National Park Service, the University of Alaska, the University of Kansas and Hokkaido University in Japan. It has already resulted in the discovery of two new species of dinosaur, the horned Pachyrhinosaurus perotorum, and a brand new Tyrannosaur named Nanuqsaurus hoglundi, and further discoveries yet to be made!

Big Bend National Park

For several years, the Museum has collected Late Cretaceous dinosaurs from Big Bend National Pak (photos), including parts of one of the largest dinosaurs in North America, an adult Alamosaurus sanjuanensis (photos). This specimen, along with remains of several juvenile Alamosaurus and a few tyrannosaur leg bones, also collected by Museum field parties, help us paint a picture of dinosaur diversity across North America just before the mass extinction marking the end of the dinosaur era.
