Les Mollusques Céphalopodes dans les Annales de Paléontologie

About more than forty papers on cephalopods have been published in the ninety one issues of the “Annales” during one century. Most are monographs contributing to enlarge our knowledge on the biodiversity of these Molluscs which play an important part in the fossil record. Jurassic and Cretaceous ammonites are well illustrated; Palaeozoic and Triassic ones, Orthoceratoidea, Nautiloidea and Dibranchiata are seldom studied. As successive issues are published, hypothesis concerning palaeontological and geological applications are proposed by authors: systematics, phylogeny, biostratigraphy, palaeoecology, palaeobiogeography. However, these ones cannot be argued every time because of incomplete knowledge or adapted concepts. Several years or decades later, these hypothesis, reconsidered in a different context and other scientific publications, are the starting point of new ideas, at once developed and then accepted. From this point of view and by their contents, the “Annales” have answered to there vocation of publishing data, carried on year by year and enriched with the discoveries of each new palaeontologists generation.
