Below is a small fossil that I think may have some mold on it. Is it actually mold, and if it is, how do I address this?

I wish this was a post to celebrate an incredible accomplishment but instead I am extremely scared that through my potential carelessness, the likely greatest find of my life may be forever changed. I just a few days ago on 6/6 found this stingray fossil at American Fossil Quarry in Wyoming just and was able to keep it because it was at that location. I have been on a road trip and have been storing it in a plastic tote bin with bubble wrap and then fish fossils underneath wrapped in paper towel. I took the lid off for a prolonged period to air out the bin and I think this was a grave mistake and let in humidity. The paper towel was all heavily damp and many of the fish fossils had very obvious signs of mold/mildew growth and discoloration. And now I fear the stingray may show some as well. I desperately need advice on repair and preservation asap. I really need help trying to fix this mess as I’m still on the road for another week. It may not be super obvious in the images but it is the areas that appear a grayish color in contrast to the orangeish brown. The last image is the closest picture I took on the day it was found to show any potential change. This was a lifetime find and I will be crushed if I’ve caused irreparable damage. Please help. Any advice in repair and preservation is greatly appreciated. And I’m sorry to all those that see this and are disappointed in the poor handling of this rare piece, I’m more than disappointed in myself if things are what they seem. And if by a miracle the stingray is perfectly fine then any advice on the fish fossils would be great.

After rebuilding my prep station to accommodate working with my new microscope, the final part was to upgrade my air delivery with a super-sized desiccant filter. I was tired of changing out my desiccant beads 2 - 3 times a day during heavy use, so I made a DIY filter using a home water filter system. Now instead of using 4 ounces of beads, I have 4 pounds! That should finally give me a decent interval between changes.

(Not sure of the tags I should use.) This is the first instance I've found of any sort of 'bloom' on a fossil in my collection. Luckily it's not the best specimen but it is an echinoid and they are not as easy to find here as in some other places. Sandstone from the Haslam(?) Fm on Vancouver Island. Is this a calcitic bloom from some sort of acid or off-gassing from something in my storage media? I'm not sure how long this has been in this condition but I think it's happened within the last 10 years. I'm trying to keep things away from my collection that might cause this sort of thing. I've got wooden (not oak) cabinets, and the little white fold-up boxes with cotton or cloth substrate. I'm trying to get rid of plastics, foams or anything else questionable, and I can't think of what else there might be that could be a problem, unless simple humidity in the Summertime will do it. (This is indoors)

I have a basic Diplomystus dentalus from the Green River Formation, Wyoming, U.S.A. that I want to mount in my bathroom - more as an art piece than anything else. What precautions do I need to take for humidity, etc. Thanks
