Ischanacanthiformes is a prehistoric order of Acanthodii or spiny sharks found in Canada, Ukraine and United Kingdom. Members of this order were nektonic carnivores,[1] eating animals that swim rather than plankton. They had slender builds, light armor, deeply inserted spines, shark-like teeth, and two dorsal fins.[1] Some species were around 2 meters (6.56 feet) long.[2] It was described by Berg in 1940.[3][4]
