Please help ID- Wisconsin

[Daniplus2]

Can you please help ID this?  Found close to the border of WI/IL.  It seems spongelike but the inside chambers leave me guessing!  NOT a professional.  Just like to find cool schtuff'.

Tabulated coral and brachipods. The first two pictures are the internal molds of brachipods. The last picture is a part of tabulated coral. Most likely Ordovician in age.

I think the brachiopod internal molds are pentamerids.

Wisconsin is that big state to the left of Lake Michigan.

Yup, that'd be the one.  We do have a couple cool things over here!

Definitely looks like an internal mold of a pentamerid brachiopod. 

 

I found a couple matrices containing pentamerid brachiopods in northeast Iowa a couple miles from Mississippi river. This one is my best specimen of pentamerids in my collection up to date right now.

thank you everyone!  Now I can put a name to it.  Never thought it would be this, though. Very cool.  

 

Darbi-  THANK YOU for the pic!
