Help with Milwaukee Area Silurian Finds: Bivalves or Brachiopod? Plus Some Oddballs

[suburbanamateur]

I posted some of these regarding my recent visits to Doctors Park in Fox Point, Milwaukee County WI. It is a known Silurian outcrop and the local websites say both brachiopods and bivalves can be found there. Well, I found some full half-shells for the first time instead of mere impressions. They look a lot like modern bivalves, but I’m still iffy on the differences between brachiopods and bivalves. I attached some examples plus a coral that looks different from the usual chain, tabulate, and rugose corals I typically find there. The final is a strange impression I’ve never seen before. 

If anyone is willing to help this noob, I’d greatly appreciate it. Recommendations for Wisconsin fossil ID guides would also be appreciated so that I do not have to keep coming here whenever I find something new.

The pictures did not end up in the order I intended

Last item looks like a Favosites type tabulate coral.

The brachiopod looks like possibly Atrypa, or Pseudoatrypa.

What about the last impression? It does not look like a coral or shelled animal I’ve seen before. Also, I edited the photos since they weren’t in the right order according to the text: sorry for any possible confusion.

If I knew, I'd tell you.    I don't, so, I said nothing about it.

 

I have no idea what that is. The one shot tells me nothing.

Maybe  other shots of the other sides would tell more, but I can't say from the single photo.

I think I did pretty good.  "2 out of 3 ain't bad. "
