Although the taxonomy of many fossil groups is still incomplete, enough species have been investigated and described to make them important tools in stratigraphy or paleoclimatology. Such large volumes of information, however, are only useful if they are organized effectively and made accessible, so that the data needed can be quickly identified and retrieved. The standard method in paleontology to organize and disseminate taxonomic information is by publication in journals. Traditionally, the careful preparation of synonymy lists is of special importance in these publications. During the last decades, a community wide agreement has been reached on a certain form for synonymy lists, and most journals now demand the use of the so-called �Open Nomenclature�. The use of Open Nomenclature allows working with taxonomic classifications that are uncertain and allows the author to comment on the identification of specimen by other authors. Open Nomenclature synonymy lists are ideally suited for information management. They can be formulated as ontologies, the taxon descriptions representing concepts and the synonymies representing directed, non-cyclic graphs interconnecting between concepts (taxa).
