Hi Rob, I'm inclined to think that this is an erratic mudstone but not sue.

Hi

I suggest as there are only fragments on the surface you may want to take it apart and see if anything whole is underneath, matrix does not look too hard.
My curiosity would certainly get the better of me.

Hard to tell unless you are holding these things (or have seen them before!)
Could even be a fossilised foetus of something in it’s half shell.

Hello and welcome to the forum,

I would have to disagree, 1, this is marine. 2, nothing like a egg shell let alone a baby anything. The things are extremely rare and are not found at the bottom of an ancient sea.

I would be interested in hearing what made you think that.

I thought the annotation on the image attached would have answered your ; why it would have made me think that.

And also when I looked it only had one image attached. The first one.

Now on seeing the other images , yes it’s not a realistic suggestion

You cannot just rely on photos, you have to know location it was found, which would point to the type and age of the rock and how it was formed and where it was formed, land or sea etc.
People can then make an educated guess if there is not a lot to go on or make an identification. Not everyone gets it right first time and everyone's ideas are appreciated that is how we all learn from each other.
