Rookie Needs Help Identifying Multiple Wisconsin Finds

[suburbanamateur]

Hello, it’s been a while. I finally found some things that look half-decent at several Milwaukee County, WI beaches where there are supposed to Silurian reef fossils. Can someone help this amateur out? I included side and back pictures of some of them if there is anything visible from those angles that can help with ID.

1 and 4 look like cross sections through a brachiopod.

 

2 is a Rugose coral.

 

3  is a Favosites (or similar)  type of tabulate coral.

 

5 Looks like another tabulate coral.

Is there a resource you recommend to get a more precise ID for the brachiopods that you recommend? Maybe not an exact species, but narrow it down more? The specimens look like different species.

Maybe @minnbuckeye would have some suggestions for resources. 

Because they are cut in half, it is difficult to say for sure, but, they look like some genus of Orthid brachiopod.  Or possibly, some sort of Spiriferidae? 

Not enough detail to say for sure.

 

How confident are you of the Silurian age of these?

When I looked up fossil hunting sites in Milwaukee County, I found a list of Silurian Reef sites on the Milwaukee Public Museum website and have only visited sites from that list. From what I can tell from other sources, those are the kinds of fossils that predominate the area.
