Cretaceous-paleogene Extinction Event

Famous quotes containing the words extinction and/or event:

    I wish all men to be free. I wish the material prosperity of the already free which I feel sure the extinction of slavery would bring.
    Abraham Lincoln (1809–1865)

    When we awoke, we found a heavy dew on our blankets. I lay awake very early, and listened to the clear, shrill ah, te te, te te, te of the white-throated sparrow, repeated at short intervals, without the least variation, for half an hour, as if it could not enough express its happiness. Whether my companions heard it or not, I know not, but it was a kind of matins to me, and the event of the forenoon.
    Henry David Thoreau (1817–1862)
