Question

Paleobiologists generally recognize the five most severe mass extinctions during the Phanerozoic Eon. Along with the other students in this class, determine when each of these “Big Five” mass extinctions occurred. Include in the discussion a brief list of which organisms went extinct during each of these events and which organisms radiated afterwards. You should use the information from this unit and from Internet searches to help you in this discussion.
I already know the five but I do not know how to add more.
