(p.301) Chapter Ten Fossil Species as Data: A Perspective from Echinoderms
Species and Speciation in the Fossil Record

William I. Ausich

University of Chicago Press

Our intuition is that species-level, fossil data are problematic for studying the tempo and mode of evolutionary history. In this chapter, the fidelity of species-level data of fossil echinoderms is considered in order to evaluate the usefulness of species for answering evolutionary and paleobiological questions. Although such species-level data are problematic for many studies, significant information is recorded by fossil species. A fossil species represents a unique morphological entity in time and space, despite varying degrees of resolution for species as a whole.
