Deskripsi
The Early Cretaceous Aptian stage represents an interval of major dramatic climate changes, but there is no consensus on its lower boundary age. Here, the authors present an astro-chronological framework that offers new age constraints on the onset and duration of Aptian ocean anoxic events and the ‘cold snap’, among other significant climatic events.
