Photo @Cory Richards A Late Cretaceous (100.5 to 66 million years ago) articulated section of Hadrosaur tail lays in-situ in the mudstone of the Kaiparowits formation of Southern Utah. Hadrosaurs were so common in this area that the paleontologists chose not to remove vertebrae. Exciting new paleontology is being done every season in the remote dinosaur-rich Escalante Grand Staircase National Monument, pulling species new to science from the badlands so frequently it seems that Laramidia, the landmass that existed during the late Cretaceous, was a veritable dinosaur factory. The article profiling the exhaustive work being done is in the May ’14 @ナショナルジオグラフィック. @natgeocreative @3stringsproductions @markstonephoto @andy_mann @ザ・ノースフェイス
