Hello,
I found these a while ago on Jebel Jais (part of the Hajar mountain range) in Ras al Khaimah, United Arab Emirates. I can't find much information on age...
I am writing something about the fossils of the UAE, but I don't have much to say about these fossils, as I do not know what most of them are! Any information will be helpful.
I have found solitary coral, like this one, at the location before.
