End_Page 716------------------------------

Recent studies of the biology and ecology of large, living, algal symbiont-bearing foraminifera have vastly improved the potential for use of these organisms for paleoecologic interpretation and as sediment tracers. Using assemblage composition, size, shape, and lamellar thicknesses, the depth and habitat of the biocoenosis can be predicted from the thanatocoenosis. Robust, commonly spinose, forms are characteristic of the turbulent intertidal and shallow subtidal zone of modern carbonate environments. Robust forms are succeeded by intermediate forms on reef and lagoon slopes. Flatter, larger forms characterize depths approaching the limits of the euphotic benthos. Presence or absence of algal symbiont-bearing species also indicates the relative primary productivity of the paleoenviro ment.
