A team of German and British scientists have used fossilised shark teeth to reconstruct the climate of the North Sea during the Palaeogene period, between 40 and 60 million years ago. The results suggest that the North Sea was for a brief period isolated from surrounding oceans, resulting in surface-water freshening and a significant reduction in the diversity of life.
