That post didn't come out in the right order or set up. I use my phone to do all of it so work with me if you can??!!??!! Sorry. Should I just do separate threads?
The phone can be a big problem.
I usually can't get that many photos before the application crashes.. I lose everything and just give up.
Sorry I'm not much help..the small round piece might be a crinoid.
Its fossilized. But those do look very similar. I actually thought it was a broken piece to some sort of metal cast until I looked it over closely. I even ran a magnet over it to make sure. Lol
The long thin one looks a lot like a crinoid. The circular segments give it away. Looks like you have the stem (Seen below) and part of the top plant Very common in Illinois/Indiana...Ancient sea bed.
