A construction crew in Cape Coral, Florida, discovered a bony fragment allegedly from a mastodon or mammoth in June, a report released Friday said.
The fragment was discovered underground by crews working on the city's expansion project, the Fort Myers News-Press reported. It is believed to be part of the humeral bone of the animal, according to The Cape Coral Daily Breeze.

It is not clear how old the find is; The news press reported that it could be more than two million years old, while NBC2 wrote it somewhere between 12,000 and 250,000 years ago.
In addition, archaeologists believe there could be more fossils in the area.

"It's a fairly large bone fragment and probably will not be the only bone in the area," Ryan Franklin, deputy director of the Archeological and Historical Conservancy Inc., said The Cape Coral Daily Breeze recounted the finding.
The bone fragment, which was about a foot long and 10 inches wide, will be donated to the Cape Coral Historical Museum.
