Lizard jaw?

[MrBones]

Found this yesterday on a hill close to shipwreck beach, Ruwais, UAE. I think it looks like a lizard jae, I found a couple pieces of tortiose shell fragments. I know it is difficult to id things from here, but you guys can tell me what you think it could be. I think it is about miocene age.

I think it is a piece of the hinge of a clam.

I don't think so, we don't have a lot of clams here. The at the end of the fossil ther is a sort of cross-section where it had broken off from another piece, ther is a hole in the middle, it looks simmilar to a bone. I have found some crocodile scutes, and other animal bones in the same location.

I took the freedom to fiddle a little bit with your pics:

(There seems to be no difference between the supposed jaw (bone) and the supposed teeth, everything seem to be the same material.)

I agree with @FossilDAWG, hinge part of a clam is very probable. But I am not 100% certain. Structure is somewhat strange for a clam shell.

Edit: Ok, if it is indeed a jaw section, than the teeth would have been in the holes, and all teeth have already fallen out, only bone left.

Are you able to provide an end view, @MrBones? Thank you!

Can't get the camera to focus on something so small unfortunately.

[Rockwood]

The plot thickens.

Yea, see, I don't think "clam hinge" fits the specimen's features, esp. having seen the end.  But I agree that the "serrated edge" does not look like teeth.  As @FranzBernhard put it so well:

"There seems to be no difference between the supposed jaw (bone) and the supposed teeth, everything seem to be the same material."

So what is it?  I'm clueless so far.  Can I phone a friend?

Sure, we all have technical limitations, but you are doing your best, thank you!

 

But I can see enough, that I can not decide between bone or clam - or something totally different.

Oh yes, but I don´t know what kind of soup it will be .

Same situation here!

perhaps a fossil gorgonian fragment? This is a guess not an ID.

Seems a bit odd for a coral to be found where crocodile scutes have been found. Good guess though.

The interior looks more like calcitic shell material than bone, to me.

Super intrigued by this

Tough to say from these photos, but I'm wondering if it could be a sunbeached, eroded fish fin spine?

The problem I ran into is the right angles in the structure. Seems unfishy.

Looks a bit like part of a crab claw.

I disagree... (sorry)

 

I'm in the weathered fish spine camp. Looks very similar to it.

My curiosity got the best of me and I was searching for a possibility when I stumbled onto this: On some Mississippian (Carboniferous) brachiopods from neptunian dykes of the Harz Mountains (central Germany) had a picture of brachiopods with this exact look. I could not copy the article without paying out a lot of money. Just throwing a possibility out there.

I showed this picture to Dr. Mark Jonathan Beech, and he believes it's a jaw from a Dhab (uromastyx) lizard.

[GallinaPinta]

So its a jaw fragment after all? 

[MrBones]

Yes, it was.

These lizards are found in archaeological settings.  Seems they are tasty...

Yes, they are still a delicacy in the middle east....unfortunately.....

I have recently found another piece similar to this one. I am wondering whether it could be a catfish barb.

Here is a photo, the new piece is on the bottom.
