A helicoprion shark is an extinct species of cartilaginous fish. It is mostly known for its rolled up jaw which contained many sharp, dangerous teeth. It grew anywhere from 13 to 25 ft. long and weighed from 500 to 1,000 pounds. Go to google and look it up.
This fish is known for its very strangely shaped lower jaw and is believed to have inhabited the earth 310 million years ago.
Helicoprion ("Spiral Saw") was a long-liced genus of shark-like cartilaginous fish that fist arose in the oceans of the late Caboniferous 280 million years ago, survied the Permian-Triassic Extiction Event, and eventually went extinct during the early Triassic some 225 million years ago. The only known fossils are the teeth, which were arranged in a fantastic "tooth-whorl" strongly reminiscent of a circular saw. http://en.wikipedia.org/wiki/Helicoprion
