Mystery fossil

Recommended Posts

MrBones

Hello, I am only 13 but I have picked up a lot of fossils. I don't know what half of the fossils are. I hope you can help. I found this fossil on the Jebal Hafeet nountain in Al Ain, UAE. It is very small.  I am curious as to what it is. It looks like some sort of coral. The area l found it in was known for its marine fossils. I also found several larger corals on the same mountain.20181230_144511.thumb.jpg.4dbc010a69553343cc58c975ba0fe67f.jpg

Thank you, I googled it and it looks identical to what I have.

I did the same. Looks like a large foram. at least.

Maybe you can post some closeups and more information about the geology/age of the rocks where you find the fossils? Beside Foraminifera it can be also a Lunulites (Bryozoa): Lunulites/Oligocene , Lunulites 2 , Lunulites 3

It's the view in the top photo I had trouble making fit.

@Rockwood: I agree with you and wouldn't exclude Foraminifera without better pictures and Informations about the geology, but it can also be a filling with sand(stone). I also know the foraminiferal limestones of this region, where eocene Nummulites are very, very common (with about 8 cm size in the UAE deposits).

 

First Picture is definitely more pointing to foram, second make doubts on this...

You know, it could be a foram. that's been encrusted by a bryozoan.

One more point for better pictures... ;) (but (sorry about my "but"s): Lunulites did not encrust and is evolved by its functional morphology for living on soft grounds (muds and fine sands). The "pore-structures" at the second picture seem to be radial symetric, so if not this genus or relatives, you are compromisless right and it is a foraminifer with one-side eroded chambers... :)

I can't disagree, but it's out of ignorance so I couldn't agree if I wanted to.

Sponge perhaps?

I was thinking sponge too, but I am very uneducated in this area. I’d love to see close up pics of it.

It looks beautiful in the second pic. It looks like it has a lot of detail.

I found several. Since they are so small it is hard to get a clear photo.20181230_210422.thumb.jpg.268108123db4cd453b7a4b2dc731370d.jpg

Hope this helps.

Upper ones are definitely something related to Nummulites. The smaller discs I will ask a friend for, foraminiferanaddicted may know his site: http://foraminifera.eu/

 

If them are Foraminiferans he will confirm...

The specimen in question looks like a half of a microspheric numulitid foraminiferan, naturally splitted in the equatorial plane, and that plane might be encrusted by bryozoan.

those might be Lepidocyclina,but don't quote me on that.

Larger operculinid forams are mostly hard to tell apart,biometry might be the order of the day

Im going to stick with nummulites, but thanks for the theory.
