We are living through the most exciting period in the history of dinosaur paleontology. More than half of all known dinosaur species were discovered within the past 25 years, including nearly all of the remarkable feathered dinosaur specimens. One of the hottest areas for dinosaur discovery in North America is the Cedar Mountain Formation of eastern Utah, where new dinosaurs are being discovered and described at a phenomenal rate. These fossil beds span the last 25-30 million years of the Early Cretaceous, a time when North America was undergoing a period of climate change that resulted in localized extinction events and invasive species. |
