Semi polished fossils id needed

Can anyone please tell me more about these fossils? and again from Hornsea south beach. I've had this rock for a few months now and i kept thinking how can i get to that detail inside, so i decided to cut it with a tile cutting disc mounted on a small angle grinder. I had a look around the net on polishing rocks but it takes too long or it costs to much, then i remembered i had an old double sided whet stone. After using the coarse side for a few minutes and then the fine side, with water and spit for about 15 minutes, i could see this amazing detail almost like a picture. I've tried this with another rock with a couple of sponges inside and you can also see great detail, but that rock was a little harder and took me about 30 minutes to do.

The semi polished rock measures 50mm

 

Thanks. Ash
