Tiny plankton slow to recover after dinosaur-killing asteroid collision

It then took a further eight million years for global species numbers to fully recover.

The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5
