Heritage Auctions in Dallas is asking at least $625,000 for a set of 9 by 11 foot jaws containing 182 teeth from a Megalodon. Four of the teeth are more than 7 inches long, a rare occurrence.

The teeth were part of the collection of amateur fossil hunter Vito Bertucci, who died in an accident in 2004. Bertucci cast the plexiglass jaws and set the teeth himself, though some scientists disagree with his assessment of the size of the jaws.
