    • Erratic bould ers of Early Carnbrian age, occ urr ing withi n the Early Miocene glac io-rnarineCape Melvi lle Formation on King George Island (So uth Shetland Island s), Antarctica, haveyielded lingul ate brachiopods including Eoobolus aff. elatus (Pelman, 1986), Karathelenapuru (Kruse, 1990) and Vandalotreta djagoran (Kruse , 1990). It is the firs t EarlyCambrian brac hiopo d ass emblage described from Antarctica . The faun a is closely similarto that from the late Early Cambrian (Toyo nia n) Wirrealp a and Aroo na Creek Limestones,Flinders Ranges, South Austra lia. The new family Eoobolidae is prop osed and the typespec ies of Eoobolus, E. triparilis (Matthew, 19(2) is re- fig ured. The evo lution of thebotsfordiid s and acro thelids is disc ussed in the light of the new materi al of Karathelenapuru, which is intermedia te in morph ology between Botsfordia and Eothe le. The superfamilyAcrot heloidea , is referred to the order Lingulida because of the similarities in musclesys tem, shell structure and deve lopment of pseudointerareas.

  • The elkaniide brachiopod Volborthia from the Lower Ordovician of Baltoscandia
  • 1995
  • Ingår i: Paläontologishes Zeitschrift. ; 69:1-2, s. 213-221
  • Tidskriftsartikel (refereegranskat)abstract
    • The rare, enigmatic brachiopodVolborthia recurva (Kutorga) is redescribed based on new, well preserved collections from the Lower Ordovician (lower Llanvirn; Oeland Series; Kunda Stage) of Ingria (St. Petersburg district); it is also recorded for the first time from Sweden, where it occurs in the Kunda Stage on the Island of Oland.V. recurva has usually been classified questionably within the order Paterinida, but the shell structure, micro-ornamentation, muscle scars, and presence of a lingulid-type pedicle groove now indicate that it is an aberrant member of the lingulid family Elkaniidae; it is the only known lingulid with a high conical dorsal valve characterised by mixoperipheral growth.
