Late Campanian Event Explained

The Late Campanian Event was a carbon cycle and climatic event that occurred during the Campanian Age of the Cretaceous Period.

Timeline

The LCE has been variously estimated to have lasted for anywhere from 0.7 to 1.0 Myr (milion years).^[1] A recent study based on a sequence in southern India gave an estimate of about 0.8-0.9 Myr,^[2] while sections in Germany and the North Sea give a length of 1.0 Myr.^[3]
