Catastrophic Events in the History of Life: Toward a New Understanding of Mass Extinctions in the Fossil Record - Part II
Catastrophic Events in the History of Life: Toward a New Understanding of Mass Extinctions in the Fossil Record - Part II
Description:
How often do mass extinctions occur? While the Phanerozoic - an interval that lasted from 253 to 11 million years ago - was punctuated by five major extinction events, there have also been numerous minor events. The boundaries between geological periods (for instance, the transition between the Jurassic and Cretaceous) are synchronized with episodes of high extinction rates.
