Famous quotes containing the words fossil and/or record:

    The earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree, which precede flowers and fruit,—not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic.
    Henry David Thoreau (1817–1862)

    Not marble nor the gilded monuments
    Of princes shall outlive this powerful rime;
    But you shall shine more bright in these contents
    Than unswept stone, besmeared with sluttish time.
    When wasteful war shall statues overturn,
    And broils root out the work of masonry,
    Nor Mars his sword nor war’s quick fire shall burn
    The living record of your memory.
    William Shakespeare (1564–1616)
