Weird find

[MrBones]

I found this fossil on a beach close to the Sir Bani Yas ferry jetty in Ruwais, UAE. I have found many invertebrate fossils in this area. This is not an invertebrate! It looks like there are pieces of ribs in the middle. I think it might belong to a turtle. The beach could have been built by pumping sand into the ocean, I don't know if that helps.

It’s part of a sawfish rostrum.

It definitely looks like a turtle shell of some sort. I'd recommend you try and clean up the loose sediment in the cavities; you'll know what it is then for sure.

Wow, that's amazing! I didn't think you would find sawfish in the UAE. Thanks for the response.

I am too afraid to use my dremel on this, I just got a dremel yesterday.

I wouldn't remove any of the matrix unless you consolidate the outside. This can crumble. As Al Dente stated this is a partial Sawfish rostrum. I would personally leave it as is and display it proudly.

Vote 3 for sawfish rostrum. Superb find!

Excellent find!
I agree with the ID. So, the patterns visible on the surface represent tessellated calcified cartilage.

Thank you all
