A Brighton, Tennessee couple received quite a shock when they tried to install a new swimming pool in their backyard: the jawbone of a pre-historic animal.
The strange and unusual discovery caught Jim Leyden and his wife by surprise.
“My wife called and said, ‘You’re not going to believe it. They can’t do anything with the pool,’” Leyden said. “I’m thinking, what happened?”
It was no mistake – as contractors dug a hole to install the Leydens’ new pool, they discovered a set of rare bones.
“They found a dinosaur,” Leyden said.
Well, not exactly. Excavators believe the two-foot long jawbone may have belonged to a close relative of the mastodon called a trilophodon, an mammal which resembles an elephant.
