The objective of this study is to study spatial and temporal paleontological distributions as they relate to the histories of Ninetyeast Ridge and Broken Ridge from ODP Leg 121. This study is important for establishing connections between different fossil assemblages, especially between those of the high latitudes and those of low latitudes. The assemblages were used to perform biostratigraphic analyses of sequences on Ninetyeast Ridge and Broken Ridge in the Indian Ocean and to compare assemblage changes to position changes of the tectonic plates through time. The zonation scheme used for the analysis is from Okada and Bukry (1980). Although there were some small changes within the assemblages of the holes described, the changes were not significant. The assemblages throughout the interval studied contained only low-latitude species. === A Thesis submitted to the Department of Earth, Ocean, and Atmospheric Science in partial fulfillment of the requirements for the degree of Master of Science. === Fall Semester, 2014. === November 7, 2014. === Calcareous Nannofossils, Micropaleontology === Includes bibliographical references. === Sherwood W.
