A city in Volusia County is trying to unearth a mystery that goes back to prehistoric times.

Holly Hill city officials said they are hoping to track down clues that will lead them to the missing fossilized remains of a mastodon, believed to have roamed Volusia County some 80,000 years ago.

According to our partners at the Daytona Beach News-Journal, city workers stumbled upon the skeleton in 1989 during construction for a water treatment plant off what was then 11th Street, now LPGA Boulevard.

The remains were thought to be stored inside a shed at Holly Hill's Public Works facility.

But when city officials recently checked the shed, the bones were gone.

"They just plain disappeared," David Rowe, general manager for the Holly Hill Museum and Cultural Center, told the News-Journal.

Now, the city hopes some someone knows what happened to the mastodon remains, so they can be properly displayed at the new Holly Hill Preservation Museum.
