A house that will soon be up for sale in Michigan may have mammoth or mastodon bones at the bottom of its backyard pond.
The Jackson Citizen Patriot reports that Steve Dodge found the bones of a giant elephant-like animal after excavating his backyard to build a pond 10 years ago.
Dodge says the rest of the animal whose bones and ivory tusks he's kept likely is at the bottom of that pond.
He says if the new owner decides to try and successfully discover more bones, he'd love to know if it's a mastodon or mammoth.
University of Michigan experts say the mammoth or mastodon has been extinct about 10,000 years.
