This gastropod was collected about a month ago in Coralville Iowa from the Cedar Valley Formation of the Devonian. I have pieced it and puttied it back together. My attempts at IDing have failed. I don't think it is a maclurite. Any experts on the Devonian life of Iowa out there??

Why Does the U.S. Army Own So Many Fossils? Turns out massive flood control projects are a great way to find dinosaurs. by Sabrina Imbler, Atlas Obscura, August 7, 2019 https://www.atlasobscura.com/articles/why-does-the-army-own-dinosaurs Yours, Paul H.

Last Autumn, I found a large favosite coral embedded in quite a bit of matrix. It measured 24cm by 13 cm, which is large for the location it was found in. It was only a coral, but I put quite a few hours into prepping this piece. Finally done!!!!

A recent trip to Coralville, Iowa provided me with these coral specimens, each unique in their own way: 1. I posted this a few weeks ago prior to removing most of the matrix from it This rugosa coral was huge!! Check out the scale. 2. The next coral might be mistaken for a mushroom: Oops, I meant this one:

After attending a field trip to the Klein Quarry in Coralville, IA, I've got several fossils that I'm not sure of. I'm fairly new to fossil hunting and my biggest fear is destroying something that would have been a nice find. This particular fossil has a lot going on on it, but I'm going back and forth on what. I've been gently removing the matrix with a soft brush on my dremel but I"m getting to delicate looking parts so until I can figure out what it might be and what the best course of action would be, I'm at a standstill. Any ideas on both possible identification and how to proceed with processing it? I tried to give an idea of size by adding a ruler but not sure how much it help. If more photos are needed, I can add more. I appreciate any feedback! Thanks so much! Update: I got more aggressive with the Dremel and used a wire brush and things are starting to make more sense now. Of course, I have a habit of seeing Trilobites everywhere but never finding any, so I ask this cautiously; Am I thinking way too optimistically to think maybe I have not only one trilobite, but a whole party of them? Here are updated photos:
