Revision of the Danian Cow Sharks, Sand Tiger Sharks, and Goblin Sharks (Hexanchidae, Odontaspididae, and Mitsukurinidae) from Southern Sweden

摘要: ABSTRACT Chemical preparation of previously illustrated selachian teeth together with recently collected material from the upper part (early-middle NP3) Danian sequence in Limhamn quarry, Skane, southern Sweden, have revealed a rich and diverse fauna. The three families dealt here, i.e., Hexanchidae, Odontaspididae, Mitsukurinidae, are represented by at least eight species, including two new ones, assigned to seven genera; Hexanchus spp., Heptranchias sp., Notorynchus Notidanodon brotzeni sp. nov., Carcharias gracilis, C. aff. tenuis, Odontaspis speyeri, Striatolamia cederstroemi nov. At genus level, hexanchid fauna is most fossil assemblage yet reported. oldest known species its tooth morphology indicates that may be more closely related Anomotodon than odontaspidids.
