Upper cretaceous

The intracontinental Benue Trough was initiated during the Lower Cretaceous in relation with the Atlantic Ocean opening. The first stage of its evolution started in the Aptian, forming isolated basins with continental sedimentation. ... In the Albian times, a great delta developed in the Upper Benue Trough, while the first marine transgression ....

In Khalda structure, the Cretaceous section was interpreted on the seismic sections covering the Khalda Oil Field. It is indicated that the Upper Cretaceous Abu Roash and the Lower Cretaceous Alam-El Bueib formations have been affected by normal faulting. Though the implication of folding is minimized, it is traceable in the field.Cretaceous Dinosaurs in Parks. Cretaceous (145 to 66 Ma) dinosaur fossils in the NPS are geographically more scattered than the Triassic and Jurassic examples. In recent years, Alaska’s parks have become significant for tracks, especially at Denali National Park and Preserve, where hadrosaur tracks are abundant.Bryce Canyon …
