A spike of woody plant biomarkers in the deep-sea iridium layer at the Cretaceous/Paleogene boundaryAuthors:Mizukami et alAbstract:At the Cretaceous/Paleogene (K/Pg) boundary, 66 million years ago, the Chixulub impact resulted in significant environmental changes and a mass extinction of dinosaurs and marine invertebrates such as ammonites. Show More Summary
A family of animals ruled the skies some 90 million years ago, but they weren't dinosaurs, and they weren't birds, and they didn't even have teeth. The winged reptiles of the late Cretaceous period belong to a family of pterosaurs called Azhdarchidae, and they appear to have had remarkable dominance...
Mammalian femora across the Cretaceous–Paleogene boundary in eastern MontanaAuthors:DeBey et alAbstract:Our understanding of latest Cretaceous and earliest Paleogene mammalian evolution is based almost entirely on the dental fossil record. Show More Summary
The horned dinosaurs Pentaceratops and Kosmoceratops from the upper Campanian of Alberta and implications for dinosaur biogeographyAuthor:LongrichAbstract:The upper Campanian of the American Southwest has produced dinosaurs that are unknown from the northern Great Plains and vice versa. Show More Summary
A new study provides an exciting insight into the diversity and distribution of pterosaurs from the Azhdarchidae family. Dominating the Late Cretaceous skies this group of toothless flying 'dragons' represent an important link in evolutionary transitions between the pre-historic times and the world as we know it today.
