Ok, What was this odd tooth-whorl used for? The tooth-whorl has puzzled paleontologists for decades, as it was unknown as to where it fit into the jaw, until a modern reconstruction determined that the most feasible place was within the shark’s mouth.This shark kept the old and new teeth. some of the sharks started to grow teeth into its mouth and or face this look was very strange and weird to most people.
