I don't recognize what's in the first pic, but after it fell out, I thought the impression in the rock looked like the end of a trilobite.

The first appears to be a bivalve (such as a rostroconch). The second is indeed a trilobite pygidium.

I thought it looked like the last bivalve I posted, but it came out of that space with the trilobite pygidium, so I was confused. Thx for the feedback!
