My Cousin's Fossil

[Ossicle]

While visiting family, my cousin showed me a fossil he collected at the coast when he was a child, cracking rocks to see what he could find. They spent a lot of time on the Jurassic coast, but also went to places like Hunstanton, which have Cretaceous layers. I'm really not sure what this is, but it's something in a flint nodule. Could it be a bryozoan?

The shape makes me think bryozoan, but I don't see any pattern that would usually be present so I think you actually have some fossil worm casts. Cool find!

It's probably a sponge - most things like that in flint are!

Something like this Pholidocladia (also in flint, but as a mould) from "Catalogue of the fossil sponges... of the British Museum", 1883.

Thank you for the great suggestions, I hadn't considered either, and both are great .

And that illustration is wonderful - there are a lot of similarities there.

I agree with Tarquin, it's probably a sponge in flint.
