They have an extraordinarily good fossil record that may be applied to broad problems of evolution of the tropical marine biota and ancillary questions about past climates and changing distributions of land and sea over more than one-half billion years of earth history. This essay is an attempt at a synopsis through the eyes of a paleobiologist of some of the existing episodes in the history of the world's oceans and their organisms. The reef community is well suited for a leading role in this history"--P.
