Hi everybody, i found those pieces in A Kimmeridgian layer for the Cidaris and a Cenomanian layer for the other pieces and I'd like your opinion upon them. 

 

Kimmeridgian Cidaris : that's the fourth time I go in that place, I always found radioles but this time i come back with a piece of test.

In the Cenomanian I found that urchin, I think this is a Leymariaster :

This one is also an urchin according to me

I think this is also the case for that piece but I'm not sure.

Acrocidaris for the first. Hemiasteridae for the second. Hard to tell if it's Leymeriaster.

No echinids for the other for me. Maybe sponge for the last
