Paleocene-eocene dinoflagellate cysts from Africa, India and Belgium

The early Paleogene was an epoch with generally much higher mean global temperatures and concentrations of greenhouse gasses than today. Superimposed on the general warm early Paleogene climate are several sudden transient (10-100 kyr scale) and extreme climatic events known as hyperthermals, which are characterized by a.o. rapid changes in surface and deep-sea temperatures, ocean circulation patterns, surface ocean acidification, precipitation and productivity. This makes the early Paleogene an extremely interesting period, as it likely represents the most recent and best analogue for the hig... Mehr ...
