Extinct group of elasmobranchs
Phoebodontiformes is an extinct group of elasmobranchs (sensu lato ), known from the Devonian and Carboniferous periods . It includes the genera Phoebodus , Diademodus and Thrinacodus .[ 1] Phoebodus and Thrinacodus have slender, elongate bodies.[ 2] Their teeth are tricuspate (bearing three cusps).[ 2] [ 3] Some studies have recovered the group as paraphyletic .[ 4]
Jalodus and other members of the family Jalodontidae , which range from the Devonian to the Triassic , were formerly included in this order, but have subsequently been assigned to their own order, the Jalodontiformes .[ 5]
