Mazon Creek Fossil ID Help

[quasar57]

Hi all,

 

I just opened up some concretions from the Mazon Creek area in Illinois, USA and was wondering if I found anything. About 90% of what I opened were blanks. I've attached the three concretions that I think are something and a picture of what I was considering blanks.

 

Thanks in advance.

Only #1 appear to have something and its pretty vague to tell what it is. Whatever it is, its marine soft body invertebrate. You can see two segmented body parts and the white lines near it might had been part of the outer border of the animal. I'm a complete rookie at mazon creek fossils, only having fern leaves and sea cucumbers I bought.

The second picture is coprolite, all others in my opinion are not fossils.
