New Indications of Gradual Decline of Dinosaurs before the End of the Cretaceous Period

According to the latest research results of a German-Mexican team of geoscientists, the gradual decline of the dinosaurs and pterosaurs presumably came before the impact of the Chicxulub asteroid and the global mass extinction at the end of the Cretaceous Period. Studies under the direction of Prof. Dr Wolfgang Stinnesbeck of Heidelberg University and Prof. Dr Eberhard Frey of the State Museum of Natural History Karlsruhe also indicate that bird species spread and diversified at the same time the dinosaurs disappeared. Their results were published in the journal “Geological Society of America Bulletin.” (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
