Sorry to ask this question again, but I have figured out how to take some clearer pictures. It comes from whitby.
It looks the right shape, but I'm not sure.
I would appriciate any answers on this one.
The image below is of a Lower Jurassic fishes scales that I found on the Holderness coast, I have another good specimen that came from Kettleness and contains a crushed fish's head and a lot of scales.
When you find some you will know what they are imediately.
