Position and orientation of the protoconchs in Pinnocaris and the Scaphopoda are different. 3 Phylogeny of the diasome mollusks. The Scaphopoda are the sister-group of the Conocardioida. We try to set up a data base for fossil scaphopods, i.e. a compilation of all described taxa. The data set for the genus comprises name, author and publication date, type species and type species selection, synonymy, geographic and stratigraphic occurrences, diagnosis, original descriptions, attributed species, and to which family it is currently attributed, and comments.
Some data sets are already fairly complete, others just contain the name of the species.
Perhaps in a few years these data sets will be available in the Internet. This data base is intended to provide the basis for future revisions, redescriptions and new descriptions. There exists an extensive bibliography on fossil Scaphopoda which is available here on this site. Although these references were collected over many years the list is still incomplete, and many papers are not yet available as reprints or copies, or even the references are fragmentary. The literature about fossil Scaphopoda is widely scattered in faunal and regional descriptions and therefore very difficult to find.
