The aim of the present volume is to assemble data on sexual dimorphism throughout the non-colonial fossil Metazoa, to enhance the study of problematic or new discoveries of such dimorphism, to discuss possible taxonomic procedures and, if possible, to form some concensus regarding classification and nomenclature embodying the hypothesis of sexual dimorphism.
