Chronology of geological events prior to the great extinction 66 million years ago

New research focusing on the last 3 million years of the Cretaceous period, managed to detail exactly the chronology of the climatic, magnetic and biological events prior to the great extinction of 66 million years ago (Ma.), which includes the disappearance of almost all dinosaurs (except birds). Scientists analyzed gravitational interactions between the Earth, the Moon, the Sun and the planets of the solar system (principally Jupiter) in their work.
