Antarctic marine life recovery following the dinosaurs' extinction

A new study shows how marine life around Antarctica returned after the extinction event that wiped out the dinosaurs. A team studied just under 3000 marine fossils collected from Antarctica to understand how life on the sea floor recovered after the Cretaceous-Paleogene (K-Pg) mass extinction 66 million years ago. They reveal it took one million years for the marine ecosystem to return to pre-extinction levels.
