The study proposed herein will explore the evolution of                 the symbiotic association between endosymbiotic algae                           (zooxanthellae) and Mesozoic scleractinian corals.  The                         aragonitic corals which will form the basis of this study                       include the oldest known sleractinians still composed of                        aragonite.  The presence of the symbiotic association can be                    documented in diagenetically unalltered fossil corals by                        examining the statistical relationships between stable carbon                   and oxygen isotopes.                                                                    We will systematically establish the geochemical,                       mineralogical, and petrographic integrity of our samples by (i)                 staining, (ii) x-ray, (iii) electron microscope analysis, (iv)                  catholuminescent studies, (v) scanning electron microscopy, and                 (vi) optical petrographic methods.  Stable isotopic analysis                    will be performed only on diagenetically unaltered samples.                     The results will be compared to other, often controversial                      methods of establishing the presence of zooxanthellae and is                    expected to provide insight into the early evolution of Mesozoic                corals.
