Possible crinoid?

Recommended Posts

While searching for fossils on Jebel Hafeet (a mountain in Al Ain, Abu Dhabi, UAE) my mother saw this little fossil sticking out of the rock face. I immediately thought it looked like a crinoid, which was odd since I have never seen one before in this country...

I carefully excavated it and brought it home.20200315_121742.thumb.jpg.1e851524d21933e6ed727d832606fdef.jpg

I think that the fossil is about miocene age, but I am not completely sure, the round things surrounding the fossil are nummulites.

Looks a bit uniformed to be crinoid. Curious to see what others think it is. Do you know what other fossils are found in that area?

Oh sorry, I forgot to say that I have found many gastropod and bivalve steinkerns, echinoderm fragments, along with corals and bryozoan in the same area

Looks more like the imprint of a bivalve shell, to me.

It does a bit, but the "columns" are 3D, some have fallen off towards the base of the fossil, where they all appear to connect. These columns also look to be independent from one another.

They resemble ray tooth plate, but I have no idea if that's even a possibility for that area.

 

 

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

Good call, found this pic online that looks very similar

Yes, it definitely resembles a ray tooth plate, and I also have no idea if that's even possible in your area, but something just doesn't look quite right to me. Maybe it looks just a bit more asymmetrical than the "normal" ray mouth plates we frequently find in NC. I always respect @Mark Kmiecik ID's, and I definitely would have given the same opinion -- until I saw the UAE locale. Again, don't know if ray plates are even possible there, but I'd like to hear from other members who might be more familiar with the area than me.

I'm not sure about a couple of million years ago, but there are eagle rays and some other types of stingrays swimming around in the modern day Arabian Gulf.

In my opinion, the specimen in question is an eagle ray mouth plate fragment showing the roots of the teeth rows.

That would be interesting!

Wouldn't that be quite small, for a mouth plate? 

Each row would only be a few millimeters wide.  :headscratch:

 

Plus this weird feature on top row.

Sorry to say, but I' ve never seen before these patterns on crinoid crowns. I will remain in the ray mouth plate camp. I could be wrong.
