Coral?

[MrBones]

Hello, I recently went on a trip to Ras al Khaimah. On our trip we visited Jebel al Jais (the highest mountain in the UAE), and I found these fossils jutting out of this rock. I thought they looked like some sort of coral, but I am not entirely sure. I would like to know what you guys think.

I’m not sure it could be a fossil but it could also easily be geological (maybe dentritic growth?) not really sure here though

They have a very distinct pattern, and they all seem to have a "mouth" or openning with lots of smaller structures inside. I've seen some dendrites before, but these look a bit different.

I'm just going to toss in what comes to mind, archaeocyathid.

That might be it! I found this image while looking up "archaeocyathid" on the internet, looks limilar to some of the fossils in the rock.

These are to the Cambrian (?) what rudist are to the Cretaceous.

So they were plentiful during that time?

Just double checked. That's when they were around. 

Hope someone can add more though. I don't know much about them.

Just to clarify for those who don't delve as heavily into concepts as I do. Both seem to present a wide variety of strange shapes.

Very probably Scleractinians, solitary corals. I have been to that area some decades ago and you have got a lot of Upper Cretaceous there (principally Campanian to Maastrichtian). Your specimen show two longitudinal sections, one flat cyclolitid (but not necessarily Cyclolites!) coral and a turbinate form.
