SEYMOUR, Ind. (AP) — Workers installing sewer lines across a southern Indiana farm unearthed the fossilized bones of a mastodon that likely stood about 9 feet (2.7 meters) tall.

The bones include most of a tusk, parts of a skull and a jawbone with teeth. They were recently dug up on a farm in Seymour, about 60 miles (96 kilometers) south of Indianapolis.

Richards says the fossil’s age will be determined using radiocarbon dating.
