Coral or urchin fossil maybe?

[The cute camel]

Hi everyone, found this fossil in limestone area in United Arab Emirates which was formed 66-74 mya, according to local geology museum. Not sure what it could be but looks very pretty for sure

This fossil was found on the ground in sandy areas where bivalves and small shells are found quite abundantly.

Welcome to the Forum.

Looks more like a bryozoan or sponge, to me.

I think the geometry of coral is there. The scale does make me wonder though.

Hard to tell.

Do you see any internal structures in the pits?

Too small? These corallites are about one mm and there are some corals with very small corallites out there. But well, I don´t see any septa etc.

It looks like Porosphaera globularis, a calcisponge.

I dont think i see any internal structures in the pits (adding here a close up pic)

but now that other members have mentioned about sponges, it does look sponge-y
