EVOLUTION OF THE EARLY TRIASSIC LINEAGE ANAXENASPIS-KONINCKITOIDES (CERATITIDA)

Abstract

The evolution of the phylogenetically linked early Triassic genera Anaxenaspis, Lepiskites, Clypeoceratoides, and Koninkitoides is discussed. This lineage shows a combination of direct and complex recapitulations. All changes in the lineage result from anaboly.
