Hello again. I got the time to scrub off my finds from Friday and found one of interest (and a second that I haphazardly split open that I think is a dud). The top one’s shape remained after several rounds of intense scrubbing, and feels slightly 3D in the middle.

 

Other views of top one:

 

 

Is there anything in the top one or is it just suggestive mineral staining? Additionally, since there is a crevice present around the entire perimeter, would you recommend I try and pry it open or leave the concretion as is?

 

 

 

Lastly, just so I can document the correct number of concretions collected on my permit, which of these four examples (if any) would you consider to be a concretion or half concretion. “a” and “d” are extremely thin, both likely part of the outer “shell” of a concretion. “b” is just an odd shape, and “c” is thick but flat. As always, thank you!

I don't see a fossil. And I don't know a single person who has ever submitted the form back, I doubt it would be read even if you did.
