Mazon Creek Identification Help Request

[Jones1rocks]

Hi all,

 

I'm still going through 20 flats of mostly unmarked Mazon Creek fossils, purchased from the estate of a prolific collector here in Central Illinois.  I have many questions about identification.  The following are a few of my still unidentified specimens, of which I realize their may be a number of worms, as well as some possible fauna.  I would like to throw these pictures out there and see if anyone can positively identify them just based on the photographs.  I'll start with number 1, and post three pictures of each.  Thanks so much!

I think this one might be similar to your other one, another cyclus, but I'm far from an expert in these things

I agree with @smt126 as it being a Cyclus.
