Wikipedia
Orthacanthus
Orthacanthus is an extinct genus of fresh-water xenacanthid sharks, named by Louis Agassiz in 1836, ranging from the Upper Carboniferous until the Lower Permian. Orthacanthus had a nektobenthic life habitat, with a carnivorous diet. Multiple sources have also discovered evidence of cannibalism in the diet of Orthacanthus and of "filial cannibalism" where adult Orthacanthus preyed upon juvenile Orthacanthus. The genus Orthacanthus has been synonymized with Dittodus (Owen, 1867), Didymodus (Cope, 1883), and Diplodus (Agassiz, 1843).About 260 million years ago, Orthacanthus was the apex predator of freshwater swamps and bayous in Europe and North America. Mature Orthacanthus reached nearly 3 meters (10 feet) in length. Orthacanthus teeth have a minimum of three cusps, two principal cusps, and an intermediate cusp, where the principal cusps are variously serrated, with complex base morphology. Additionally, Orthacanthus can be diagnosed by major transverse axes of proximal ends at a 45 degree angle to and often almost parallel to the labial margin of the base between the cusps. Deformed teeth are characteristic of the xenacanth sharks and of Orthacanthus.

Orthacanthus
Orthacanthus is an extinct genus of fresh-water shark from a family of prehistoric sharks known as xenacanths. Members of the genus had a long spine growing from the back of their skull and a very long dorsal fin, which ran all along its back giving it an eel-like appearance. About 260 million years ago, Orthacanthus was the apex predator of freshwater swamps and bayous in Europe and North America. Its body reached nearly 10 feet in length and owned a peculiar set of double-fanged teeth. They first appeared about 400 million years ago in the Devonian, and became extinct just before the Mesozoic, about 225 million years ago.
