Hi,
I'm not convinced on the bivalve I.D.

I still say its an impression of part of the ambulacrum section from in particular, a Tylocidaris.

I have tweaked your photo & resized it, now I'm almost certain thats what you have found.

From your description & what i can see, i think its an impression or part of the ambulacrum area of a cidaris type of echinoid.
They do look a bit zip like & is that some tubercles i can see as well?

Cheers

Keith

thanks keith but there doesnt seem to be any tubercles,as that was my first thought(though they could be worn away)

 It's a bivalve imprssion/mould.

 The zip like markings are the crystal growth in the shell - they look like bars up and down (90 degrees to the edge of the shell.

 I tried to find some images of it on google but no luck atm.
