I was hammering a large chunk of limestone when this popped out. I dug the original rock out of the ground in southern Macon County, IL. From all of the ISGS information that I've read, I know this particular location lies atop the Shelbyville Moraine. I hope that's enough information for everyone.

Lookin' like a brachiopod, but that's all I got.

What are its dimensions?

Brachiopod for sure and, yes, dimensions would help. Central Illinois has a lot of Mississippian rocks. If this brachiopod is quite large - several inches across - you might want to compare some images of Spirifer grimesi - from the Burlington Formation.

Sorry about that. Here's a penny for scale.

If it is Mississippian it could be Brachythyris
