Helicoprion or the "Spiral Saw" ratfish. A type of "shark" that roamed the waters of the late Carboniferous 310 million years ago. It is disputed about how exactly it fits together but some scientists believed it had no top row of teeth. Only a bottom row of razor sharp teeth that were perpetually replaced by the "buzzsaw" enclosed fully by the jaw.
