Thrinacodus is an extinct genus of basal elasmobranch, found worldwide from the Late Devonian-Lower Carboniferous. The type species is Thrinacodus nanus. [1] Most species are only known from their tricuspid teeth. T. gracia, originally placed in the separate genus Thrinacoselache from the Serpukhovian-aged Bear Gulch Limestone, of what is now Montana, is known from full body impressions, showing a long, slender eel-like body up to a metre in length, with an elongate rostrum. [2] [3] [4] Stomach contents of T. gracia include remains of crustaceans and small chondrichthyan fish ( Harpagofututor and Falcatus). [2] It is a member of the Phoebodontiformes. [4]
