Abstract.-

According to when they attained high diversity, major taxa of marine animals have been clustered into three groups, the Cambrian, Paleozoic, and Modern Faunas. Because the Cambrian Fauna was a relatively minor component of the total fauna after mid-Ordovician time, the Phanerozoic history of marine animal diversity is largely a matter of the fates of the Paleozoic and Modern Faunas. The fact that most late Cenozoic genera belong to taxa that have been radiating for tens of m...

	When bivalves took over the world Paleobiology ; Abstract.- The end-Permian mass extinction is commonly portrayed not only as a massive biodiversity crisis but also as the time when marine benthic faunas changed from the Paleozoic Fauna, dominated by rhynchonelliform brachiopod taxa, to the Modern Fauna, dominated by gastropod and bivalve taxa.
	Evenness of Cambrian-Ordovician benthic marine communities in North America Paleobiology ; Abstract.-Biodiversity has two principal components: richness (the number of taxa) and evenness (the distribution of individuals among taxa). Both of these attributes are critical in defining community composition and structure, but evenness may be particularly important for ecological reasons,
	Changes in theoretical ecospace utilization in marine fossil assemblages between the mid-Paleozoic and late Cenozoic Paleobiology ; Abstract.- We present a new three-dimensional theoretical ecospace for the ecological classification of marine animals based on vertical tiering, motility level, and feeding mechanism. In this context, analyses of a database of level-bottom fossil assemblages with abundance counts demonstrate

	Paleobiology, community ecology, and scales of ecological pattern. Ecology ; INTRODUCTION Ecologists and paleoecologists have become increasingly interested in questions of spatial and temporal scale. Regional processes and historical events are now widely recognized as playing vital roles in shaping biological communities (e.g., Ricklefs and Schluter 1993, Brown 1995). The
