Possible Graptolite and more in this hash plate?

[Recker]

I found this along the Whitewater River in Southeast Indiana and trying to id looking at my book.  I'm a newbie and trying my hand at prepping using a needle vise, but the more I uncover the more I find.  Wondering if you could shed some light on what all is in this "rock".  Thanks so much, meanwhile I'll keep pecking away and try to clean this up a little more!

I'm sorry, the last photo is the back side, still lots of goodies in there.

I think, I see bryozoans and/or corals in the matrix, but I'm unsure of the specimen below. Can you take a higher resolution image of that area?

The main mass seems to be a pachyporid tabulate coral and the smaller darker lumps maybe bryozoa.

abyssunder,  I tried to get a better photo of that particular spot, I wonder if it isn't a small shell on edge?    I'm also curious about why some of the "shells" are red and others gray.  Like this one I've been prepping.

Thanks for the Photo.

The different color may be of the mineral content in the diagenesis.

At 11, and 2 o'clock on the back side look like the best views of the smaller ones. They would almost have to be bryozoans I think.

Agreed.

The Brachiopods likely were living in a slightly different  environment to begin with.
