Middle-Late Triassic chondrichthyans remains from the the Betic Range (Spain)
2017
Purpose In the present study, we described, for first time, the chondrichthyan fauna from several Middle-Late Triassic sections in the Betic Domain and compare it with other recent described coeval faunas from the Iberian Ranges. Methods Specimens were retrieved after the dissolution (with 10% acetic acid) of carbonate rocks. Results The assemblage comprises of seven species belonging to six genera (Hybodus plicatilis, Omanoselache bucheri comb. nov., Omanoselache contrarius comb. nov., Lonchidion derenzii, Lissodus aff. L. lepagei, Pseudodalatias henarejensis and cf. Rhomaleodus budurovi), most of them non-nesoselachian. Chondrichthyans remains occur in levels dating from Ladinian to Carni…
The chondrichthyan fauna from the Middle Triassic (Ladinian) of the Iberian Range (Spain)
2013
ABSTRACT Here we present for the first time a detailed taxonomic study of a diverse chondrichthyan fauna from the Middle Triassic of the Iberian Range (Spain). The assemblage consists of isolated remains of seven species of five non-neoselachian shark genera (Palaeobates, Hybodus, Pseudodalatias, Prolatodon, gen. nov., and Lissodus), including a new species of hybodontiform shark, Hybodus bugarensis, sp. nov. In addition, a new homalodontid genus, Prolatodon, sp. nov., is erected for the taxa ‘Polyacrodus’ bucheri and ‘Polyacrodus’ contrarius. The chondrichthyans of the Iberian Range represent a heterogeneous group from a paleogeographic point of view made up of common components of Middle …
