Catalog of species-group names of Recent and fossil Scaphopoda ...

Steiner G. & Kabat A. R.APPENDIX 4Geological catalog of fossil species.The fossil species that are currently treated as valid– i.e. neither junior synonyms nor juniorhomonyms – are indexed by geological period(Paleozoic and Mesozoic) and epoch (Cenozoic).However, it must be emphasized that some of thisinformation is based on the older literature, whichmay have been based on erroneous or outdatedstratigraphic determinations. A question mark (“?”)before a species name indicates a doubtful placement;at the end are those elusive species describedonly as “fossil” but without further stratigraphicdetails. Many of the Pleistocene and some of thePliocene species are also known from the Recent, asindicated in the main catalog. Generic placementsare as in the original description, except for thoserelatively few fossil species that were subsequentlytransferred to other genera. The sequence of geologicaleras, periods, and epochs, and the assignmentsof stages and other subdivisions to epochs, istaken from Harland et al. (1990).It must be emphasized that the majority of fossilspecies listed herein have not been analyzed in anysubstantive manner since the time of Pilsbry &Sharp (1897-1898). Hence, their inclusion in thisAppendix is merely a compilation of nomenclaturallyavailable names arranged by stratigraphictime periods. Thus, the numbers of species namesfor each time period should not be taken as anactual measure of paleontological diversity, whichwill require a modern determination of the phylogeneticvalidity of each described species.PALEOZOICCambrianNoneOrdovicianiowaensis, Plagioglypta (James, 1890)kentuckyensis, Rhytiodentalium Pojeta & Runnegar,1979Siluriangranosum, Dentalium Eichwald, 1857notabile, Dentalium Eichwald, 1857Devonianapplanatum, Dentalium Torley, 1908crox, Dentalium Keyserling, 1847ibergense, Dentalium Römer, 1855patriciae, Laevidentalium Engeser & Riedel, 1992?saturni, Dentalium Hoeninghaus, 1836?tenuissimum, Dentalium de Koninck, 1876Carboniferousacumen, Dentalium (de Koninck, 1883)acutisulcatum, Dentalium Gurley, 1883annuliferum, Dentalium Pilsbry & Sharp, 1898annulostriatum, Dentalium Meek & Worthen, 1871barquense, Dentalium Winchell, 1862batheri, Dentalium Finlay, 1927chubutensis, Dentalium (Laevidentalium) Sabattini,1979cornu, Dentalium de Koninck, 1877cyrtoceratoides, Dentalium (de Koninck, 1883)dentaloideum, Dentalium (Phillips, 1836)grandaevum, Dentalium Winchell, 1863herculea, Plagioglypta (de Koninck, 1863)illinoiensis, Dentalium Worthen, 1883ingens, Plagioglypta (de Koninck, 1843)kansasense, Dentalium (Paleodentalium) Gentile,1974longistriatum, Fissidentalium “?” Yoo, 1988meekiana, Plagioglypta (Geinitz, 1866)mexicanum, Dentalium Girty, 1909missouriense, Dentalium Swallow, 1863navicanum, Dentalium Ryckholt, 1851novaresei, Dentalium (Plagioglypta) de Stefani, 1917numerosa, Plagioglypta Yoo, 1988obsoletum, Prodentalium (Hall, 1858)ornatum, Dentalium de Koninck, 1843orthoceras, Dentalium Pilsbry & Sharp, 1898perarmatum, Dentalium Ryckholt, 1851primarium, Dentalium Hall, 1858priscum, Dentalium Goldfuss, 1841prosseri, Plagioglypta Morningstar, 1922protuberans, Pipadentalium Yoo, 1988raymondi, Prodentalium Young, 1942rectiusculum, Dentalium Eichwald, 1857runnegari, Scissuradentalium Yoo, 1988semicostatum, Prodentalium (Girty, 1911)subannulata, Plagioglypta Easton, 1962subcanaliculatum, Dentalium Sandberger &Sandberger, 1856taeniolatum, Dentalium Sandberger & Sandberger,1856venustum, Dentalium Meek & Worthen, 1861verrucosum, Dentalium Eichwald, 1857walciodorense, Dentalium (de Koninck, 1883)718ZOOSYSTEMA • 2004 • 26 (4)
