Xenacanthus (SciiFii)

The conger shark (Xenacanthus macrocephalus) is a species of freshwater shark that originally lived in the later Devonian period to the end of the Triassic, 202 million years ago as an extinct species of Xenacanthus and was once extinct, but has since been brought back from extinction by SciiFii and now lives in Paleozoic Park located at Downey, California. The dorsal fin of the conger shark is ribbonlike and runs the entire length of the back and round the tail, where it joins with the anal fin. This arrangement resembles that of conger eels, and the conger shark swims in a similar manner, hence its name. The conger shark has a spine that is projected from the back of the head, which is venomous in a similar manner to a stingrays, protecting the conger shark against any potential larger predators. The teeth had an unusual "V" shape, and it probably fed on small crustaceans and heavily scaled palaeoniscid fishes. The conger shark is the apex predator of freshwater swamps and bayous in its own exhibit, growing on average of around 6.6 feet (2 meters) in length and the shark possesses a peculiar set of double-fanged teeth.
