Sphenacanthus (from Greek: σφήν sphḗn, 'wedge' and Greek: ἄκανθα akantha, 'spine') is an extinct genus of a chondrichtyan xenacanthiform that belongs to the family and lived from the Late Devonian, through Carboniferous until the Late Permian period in Scotland, Spain, Russia and Brazil. It lived 359 million years ago, and probably it was one of the first member of the elasmobranchians, the lineage that leads to the modern sharks. Sphenacanthus probably hunts small fishes and, unlike their modern-day relatives, its inhabited fresh water lagoons. Sphenacanthus had seven fins, two in the upper part and five in the underside, and it had a heterodont dentition and mandibles relatively long and deeper. Sphenacanthus serrulatus is still only known from incomplete neurocranial remains and associ

dbo:abstract
  • Sphenacanthus es un género extinto de pez condrictio ctenacantiforme perteneciente a la familia de los esfenacántidos que vivió durante el período Carbonífero en Escocia,​ España,​ Rusia​ y Brasil.​ Vivió hace unos 359 millones años, y fue uno de los primeros miembros de los elasmobranquios, el linaje que conduciría a los tiburones actuales. Sphenacanthus probablemente cazaba a otros peces pequeños y a diferencia de sus parientes modernos habitaba en sistemas de agua dulce. Sphenacanthus tenía siete aletas, dos en la parte superior y cinco en la parte inferior, además de poseer una dentición heterodonta y mandíbulas relativamente largas y altas.​ (es)
  • Sphenacanthus est un genre éteint de requins préhistoriques de l’ordre également éteint des Xenacanthiformes. Il a vécu du Dévonien au Permien (-359 millions d’années). Son espèce type est Sphenacanthus serrulatus (Agassiz, 1837). Sphenacanthus chassait probablement de petits poissons et vivait dans des lagons d’eau douce. (fr)

Sphenacanthus had seven fins, two in the upper part and five in the underside, and it had a heterodont dentition and mandibles relatively long and deeper. Sphenacanthus serrulatus is still only known from incomplete neurocranial remains and associated dermal material. These suggest that it was a relatively large shark, probably well over one meter in length when fully grown. Its body form was probably similar to that of other phalacanthous sharks. (en)
