Search for " Ammonite fossils."

It's a nautiloid ammonite. A marine cephalopod in this sub-class:

In general, coiled nautiloids like this aren't that common in Missouri but will usually be from somewhere in the Ordovician period and around 450 million years old. I doubt we could get to a definitive species name.

Nice find.

Jim - the two posts above are spot on. I'm not far from Defiance. Nice find.
