    Taeniopteris novomundensis sp. nov. — "cycadophyte" foliage from the Carnian of Switzerland and Svalbard reconsidered: How to use Taeniopteris?2015Ingår i: Neues Jahrbuch für Geologie und Palaontologie - Abhandlungen, ISSN 0077-7749, Vol. 275, nr 1, s. 19-31Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Recent findings of Taeniopteris-like foliage from the Carnian of Hopen, Svalbard, necessitated the re-evaluation of entire-margined Taeniopteris foliage from the Carnian flora of Neuewelt, Basel, Switzerland, revealing the illegitimate status of Taeniopteris angustifolia. The specimen from the Ladinian or Carnian (Lower Keuper) of Lower Franconia, Germany, on which the identification was based, was recently identified as the holotype of the marattialean fern Danaeopsis angustifolia, of which Taeniopteris angustifolia is the basionym. This implies that the Neuewelt specimens, which are different from the specimens from Franconia, lack any type and basionym, and a new species name is required. The specimens from Hopen as well as specimens elsewhere from Svalbard are identified as conspecific with the specimens from Neuewelt, and we here assign all specimens to Taeniopteris novomundensis sp. nov., which is thus known from the Carnian of Switzerland and Svalbard. Information on epidermal anatomy is not available, and the affinity of the species can, therefore, not be elucidated further, but is here interpreted as a cycadophyte. Several specimens from the Carnian of Franconia assigned to Taeniopteris angustifolia belong to a species different from Taeniopteris novomundensis, i.e. Taeniopteris kelberi. Earlier inclusion of some of the specimens now assigned to Taeniopteris novomundensis in Taeniopteris kelberi is unsupported. The typification and use of Taeniopteris are discussed in this framework.

    New data on Selaginellites coburgensis from the Rhaetian of Wüstenwelsberg (Upper Franconia, Germany).2016Ingår i: Neues Jahrbuch für Geologie und Palaontologie - Abhandlungen, ISSN 0077-7749, Vol. 280, s. 177-181Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A branched shoot with several attached microsporangiate strobili of the Rhaetian (late Triassic) herbaceous lycophyte Selaginellites coburgensis is described from Wüstenwelsberg near Coburg, Germany, the locus typicus of the species. The strobili all contain Uvaesporites-type microspores, precisely as the single, detached strobilus fragment found in association with one of the original specimens

    A Selaginellites from the Rhaetian of Wüstenwelsberg (Upper Franconia, Germany)2014Ingår i: Neues Jahrbuch für Geologie und Palaontologie - Abhandlungen, ISSN 0077-7749, Vol. 272, s. 115-127Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sterile shoots and a microsporangiate strobilus of a new herbaceous lycophyte, Selaginellites coburgensis nov. spec., are described from the Rhaetian (uppermost Triassic) of Wüstenwelsberg near Coburg, Germany. Shoots branch dichotomously and bear two lateral rows of larger and two median rows of smaller microphylls. Sporophylls are scale-like; sporangia contain Uvaesporites-type spores, which permit a direct comparison of macrofossil evidence with the dispersed spore record. Sellaginellites coburgensis is significant because lycophyte macrofossils are exceedingly rare in the Rhaeto-Liassic of Franconia. The plant probably grew in habitats that were shady and relatively humid, perhaps within dense vegetation and/or in close proximity to bodies of water that locally provided a favourable microclimate.
