The ammonite groups we treated in this Catalogus are in general not used for precise stratigraphy because the genera and species have often long ranges over several zones and stages. For this reason we have included the genera and species of the Upper Cretaceous. Otherwise it would be a unnatural cut off for phylloceratid and tetragonitid (sub)genera like Phyllopachyceras, Hypophylloceras, Anagaudryceras, Gaudryceras, Kossmatella and Tetragonites and for the haploceratid family Binneytidae. Some genera and species around the Jurassic-Cretaceous boundary are also considered because we do not know their exact stratigraphical position and, moreover, the IUGS did not rule on the boundary between these two systems. Once more specialists that are active in research on this superfamilies took part in the present Fossilium Catalogus. For decades Bernard JOLY studied the Jurassic and Cretaceous Phylloceratina. He is the author of three important monographs on the Phylloceratoidea, two on the fauna of Madagascar and one on that of France. He revised the phylloceratid species of the Cretaceous described by ALCIDE D’ORBIGNY in his ‘Paleontologie française, Céphalopodes crétacés’. The achievement of Zdenĕk VAŠÍČEK is a long list of publications on the Lower Cretaceous ammonites and stratigraphy of the Carpathians of the Czech and Slovak Republics, Upper Austria and the Northern Calcareous Alps. He revised the ammonites described by UHLIG of the ‘Teschener & Wernsdorfer Schichten’. The senior curator for Invertebrate Paleontology at the National Museum of Nature and Science of Japan, Yasunari SHIGETA, has published on the Upper Cretaceous biostratigraphy of Japan and Sakhalin (Russian Far East) and on the systematics of Tetragonites, Pseudophyllites and Gabbioceras. In 2001 his book „Ammonitology“ appeared. René HOFFMANN is finishing his Ph D thesis on ‘Functional and phylogenetic significance of the septallobe in lytoceratid ammonoids’ at the Free University of Berlin. He gave us a fresh view on the systematics of the Lytoceratina. His comments on (sub)families and genera of the Lytoceratoidea and Tetragonitoidea are to be found in the Appendix.
