South Dakota Mystery Fossil.

[JMaynard]

Hey guys, I'm hoping you ID wizards can help me out and work your magic on an ID for this fossil. My 10 year old found it in South Dakota in the Mt. Rushmore area.

What you have there is part of an ammonite.

I was kind of thinking that, but it just wasn't clicking. Its this part right?


Ok I know I circled the void, but I'm meaning the baffles.
