This is a replica of the largest known, complete shark tooth that has been found to date. If the ratio of tooth size to body length for the living Carcharodon (Great White Shark) is the same for Carcharocles, the shark that this tooth came from would have been over 70 feet (21 m) in length! That would make this shark the largest known carnivore that ever lived, and it would have had a mouth so large that a human could have walked upright into it.
Peter Larson discovered this tooth during one of his trips to Peru, where he stumbled across it in a tire track! The original specimen is in the collection of Black Hills Institute of Geological Research.
