Cretaceous%e2%80%93paleogene Extinction Event

Famous quotes containing the words extinction and/or event:

    Man is an over-complicated organism. If he is doomed to extinction he will die out for want of simplicity.
    Ezra Pound (1885–1972)

    This event advertises me that there is such a fact as death,—the possibility of a man’s dying. It seems as if no man had ever died in America before; for in order to die you must first have lived.
    Henry David Thoreau (1817–1862)
