Limestone mine

The second and fourth photos show very little detail since it's too bright, but they appear to be pieces of shell. From what I couldn't say. Photos 3 and 5 show part of what may have once been a gastropod (snail). I think that the object in matrix in the last photo is rather a gastropod than an ammonite. Can you say anything to the stratigraphy? Jurassic? Cretaceous? Cenozoic?

Cenozoic era ,a Miocene epoch I think.

Miocene has no ammonites, they died out in the K-T extinction.

It is a gastropod. I can't see the other ones the best, try using natural light, it works better.

Hmmmm the spheroidal one looks a bit like a lobster carapace but could just be a crushed mollusk.

I think that's a crushed mollusk too

I've cropped and edited some of your photos. 

I believe you have bivalves and a gastropod. 

I can see growth lines on the curved/oblong items.

The one on the right in matrix in the 2nd to last photo is a bivalve.
