A young Pennsylvania archaeologist is being hailed for the find of a lifetime. The 8-year-old unearthed a prehistoric shark tooth while on vacation with his family.

Riley Glacely, of Lebanon County, found a prehistoric shark tooth during his trip to a dig site in South Carolina.

The tooth is nearly 5 inches. It's a giant tooth that belonged to a pretty large and very, very old shark.

The tooth is identified by the matching cups on each side. It's likely worth a couple thousand dollars.

But Riley says he can't wait to dig around more to see what else is out there to find.
