Worker discovers woolly mammoth tooth at Iowa construction site

It's more common to discover individual mammoth teeth than bones or complete remains, Widga said, as they are made of enamel, which is denser and "more robust to the kinds of things that break down a skeleton."

And Northwest Iowa is "kind of a hotspot" for mammoth finds, Widga noted, with discoveries tending to range between 24,000 and 15,000 years old. Around 18,000 years ago, the central part of Iowa was covered with ice. But the edges of the state were exposed -- and these areas tend to turn up mammoth remains.
