Phylogeny of the Late Paleozoic superfamily Adrianitoidea Schindewolf (Ammonoidea)

The current state of knowledge on the Late Paleozoic ammonoid superfamily Adrianitoidea is reviewed. The section on Adrianitoidea in the revised edition of the Treatise on Invertebrate Paleontology ( TIP ) on Carboniferous and Permian ammonoids (Furnish et al., 2009) is discussed. Major phylogenetic trends in this superfamily are reconstructed. New data on the morphology of members of the subfamilies Adrianitinae, Emilitinae, and Pamiritellinae allow convincing hypotheses of the early evolution, diversification, and decline in each of the above groups.
