Famous quotes containing the word fossil:
“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.”
