Life in ocean abyss recovered quickly after end-Cretaceous mass extinction event
Washington DC (UPI) Jul 14, 2020
Researchers said Tuesday that organisms in the ocean's abyss were able to recover quickly after the end-Cretaceous mass extinction event which killed off dinosaurs 66 million years ago. An asteroid hit earth at the end of the Cretaceous period creating the Chicxulub Crater in the Yucatan Peninsula, Mexico, and wiping out 75 percent of species on earth, including non-avian dinosaurs.
