Jurassic Coast ID please...

[MrsD]

Hi, first time fossil hunter here - so apologies in advance! Currently visiting the Isle of Wight Jurassic Coast and spent the day at the beach and have a couple of interesting finds - just not sure if what I found is actually anything more than just a pretty rock! 
 

So, this first one is about 11cm in length and had a sort of white slightly porous texture, with yellow brown markings. One marking has the texture of tiny bumps, whilst the other looks like smoother ridges. Can anyone please help?

The whole thing is a water-worn rock, but that pattern looks like a fossil bryozoan.

Interesting! Thank you so much for replying!

Welcome to the Forum! 

I think you have a weathered flint nodule in question that reminds me of a possible bivalve, something like a Trigonia maybe, in the core.

Welcome and have fun on the IoW, it's a great place. Just to clarify there aren't any Jurassic sedimentary rocks on the Isle of Wight, the rocks are either Cretaceous or more recent. The Jurassic Coast is on the mainland in Dorset and Devon.

Yes, in the photo number 5 and 6 I see also the impression of a bryozoa. It seems, that in the hollow, where the chalky zoarium weathered, little crystals growed up.
