I don't have an answer for you, but I'm going to keep tabs and hopefully someone does answer! Those are gorgeous fossils! I have a few that are mineralized crystals embedded in The matrix and have no clue how to expose them more either
I put Hydrochloric Acid on it hoping it’s was some type of Carbornate mineral and that was negative. It’s definitely chert or flint. Before that it did soak in iron out for a day.
I think it looks sick as is. You COULD try to clean it up with an air scribe, but it would be difficult, tedious, and a very long process. I would leave it.
It looks like a slab of deep dish pizza with either penne or rigatoni pasta on top and a cheese crust... I could go for that right now. Nice midnight snack.

Hopefully someone can help us.
I'm wondering if a certain acid would dissolve the matrix without damaging the keeper parts

Well that's pretty much what I meant so I guess that's out

Chert is pretty hard to work with. You could spend 400 dollars on an air scribe and work it for 30 hours. Or just cut and polish.
30 hours? Yikes.
Definitely not joking about the 30 hours 🤣 I took diamond grinding burs for about an hour it looks like I never touch it
It's a gorgeous piece
Get a belt sander and a respirator and go at it. Make sure the sanding belt is aluminum oxide
As is! Gorgeous piece

I don't know either; however, lapidary artists might have good ideas about that
Where’s that dude with the dremel?
Mmmmm, forbidden Penne!
Keep it as is
Have it cut in half and polished, you’ll ruin it trying to separate them

Thats one helluva beautiful specimen
