I see crinoids. Is there anything else? Is the curved moon shaped thing a bent crinoid? What about the triangle thing is that a crinoid top? 
Also can anyone tell me anything about the age or type of this limestone ? It is very bright white.

Can you give us the county/city of your find?

I think the curved moon may be a gastropod. Platyceratid gastropods are sometimes associated with crinoids, but that doesn't count as an ID.

Adair county Missouri. It was with gravel so it may have been brought in from a quarry in a county nearby

I think the donut at the top may also be a crinoid disk. Crinoid disks can be > 1 inch across and it looks like the donut is smaller than that (though I can't rule out gastropod).

 

The triangle thing could be a crinoid spine (or a broken piece of nearly anything).
