Lake Michigan Fossil ID

[Judilux1]

Hi.  I am new to fossils and have found quite a lot on a Lake Michigan beach Wisconsin side.   I would  be very grateful for any information as to the type of fossils I'll be posting photos of here. 
Thank you.    I have over 50 pounds of fossils of various types.  A great number of the fossils I have are in quartz and quite sparkly.  These are the first few I'd like to share.  Any thoughts?

I would wager a guess that these are Devonian-age coral. The last three images in particular are tabulate coral. What you are seeing is not likely quartz, but another mineral common in limestone called calcite.

 

Here is a bit more about the tabulates: https://en.wikipedia.org/wiki/Tabulata

And calcite: https://en.wikipedia.org/wiki/Calcite

 

And, finally, a very nifty site that showcases several Devonian fossils of Michigan (very much worth perusing): http://michiganbasinfossils.org/

 

Although you are on the Wisconsin side, there are portions where the exposed strata is shared.

The first is a chain coral. Maybe Halycites and possibly Favosites sp. for the other ones?

I'll go along with that.

Michigan has both Devonian and Silurian.  So halycites is appropriate.

I would agree with the earlier IDs. I'm guessing your hunting grounds are along the beaches of southern Door and Kewaunee Counties. Probably the same places we go. Nice finds.

I agree with fossildude19 on the ID's
