Mazon creek arthropods

[TheRocksWillShoutHisGlory]

I'm wondering if anyone can identify some mazon creek fossils the first 3 I think are shrimp or molts

 

The 4th I was told was a "dragonfly body" I'm not sure what to think about that and am wondering if there is anything identifiable as an insect

 

Finally it's not an arthropod, but just a curious color difference I'd like help with

The first two I agree are probably shrimp molts. The third one is not identifiable from what I can see. There may be more fossil still not exposed in the part of the nodule on the left. I would freeze/thaw that and hang on to the right side just in case there is. The "dragonfly body" is probably not. Looks more like coprolite or a poorly preserved worm. The last one may be plant stem pith, but MC material has many color stain specimens that are not identifiable and may have been something like slime, or other partially decomposed organic material. Looking forward to seeing what else opens up for you.
