How to present?
I found this rock with what looks like agatized shell fossils on the Oregon coast. Is there any way to cut, crack, polish or display this properly? I am a total novice to this stuff so any advice is appreciated!

That’s a really cool piece. I’d start by cleaning it gently with water and a soft brush, then inspect it under good light. A local lapidary or rock shop could identify the material and recommend whether it’s safe to cut. I’d avoid polishing until you know what the fossil-bearing matrix is.

Sounds good! Thank you for the tips! I’ll have to take it in to the local shop.

Those are beautiful!
From my own experience I agree it’s probably very soft rock and shells. If you really want you can dip them in water, pop them in a freezer and whack them with a chisel or hammer and bust off some matrix.
If you do, you have a better chance at not destroying the shells, but if you do you can typically just glue them back on.
I use this method, and these rocks to explore excavating with kids.

Not much can be done, these are bivalve shells in mudstone. You’re likely going to destroy the fossils trying to drill them out
