Any identificationfor this Uzbekistan tooth would be helpful - UPDATED NEW PHOTOS

[AJ the Tyrant]

I came across this tooth recently, but I (nor the seller) can figure out a decent identification for it. It’s an unknown theropod tooth from the Bissekty Formation in Uzbekistan. This is what the seller said about the specimen, “This tooth is much different from other Tyrannosauroid teeth from Bissekty. Less compressed and more rounded with much finer serrations. I believe it may be an undescribed species of theropod.” Is there any way to figure out at least a vague identification for this tooth?

If it’s from Bissekty, a good potential ID would be Timurlengia. Most of the other theropods from that region were small. However, the tooth you’re showing is indeed quite a more rounded at the base. Timurlengia tend to be more blade like. 
 

Hopefully someone else is able to help! Lovely tooth.

I’m not entirely sure. Is there any restoration on it?

 

There appear to be some ridges on the face of the crown in the second photo, almost like in ceratosaurus teeth. Are these 3D/textured or is the light playing tricks?

@Troodon thoughts?

Need to see photos please post

[TyrannosaurusRex]

Here’s photos of the piece for AJ. 

[Troodon]

Like to see additional photos more lighting, crown too dark,

A serrations count both carina midline 5mm wide. 

Like to see a clearer closeup of the distal carina. 

Possibilities include and anterior Ulughbegsaurus or even anterior Timurlengia

Are you sure about the provenance?

no restoration was mentioned

messaged seller asking for more pictures and if they are completely confident in the collection site

Seller is 100% confident in provenance, but they won’t be able to provide more pictures until tomorrow night as they are currently out of town.

Thanks, an accurate serration count is the most important characteristics needed.

These are more pictures that the seller just provided me with to help better identify this unknown tooth. I made sure to acquire some much more detailed pictures of the denticles.

new pictures have been posted!

Where and what about serration count?

will contact seller for serration count soon (sorry i must’ve missed that in your reply yesterday)

It's best to add these pictures to the existing post instead of starting a new one.

seller is being very annoying/rude for some reason and won’t provide a serration count; they said the tooth matches what is known for Timurlengia and not other species of the region(which contradicts their previous words)

 

if they decide to be helpful, i will provide further information

[Troodon]

Without that information I cannot help you,   photos are just part of the identification process

after much convincing, i have the counts

 

18 per 5mm on mesial (not exactly midline because it’s worn)

 

20 per 5mm on distal

oh by the way, i’ve been meaning to ask: how many teeth examples have you seen that can likely be attributed to Ulughbegasaurus @Troodon

Great, that serrations density fits into the Timurlengia range but those described were lateral teeth.   Looking at all the features I would lean toward an anterior Timurlengia although I have not seen any anterior ones published and what the base cross-section looks like.

 

I've seen a couple of Ulugh.. privately but no teeth were with the holotype so they are still a lot of unknowns which is typical of most of Uzbekistan's theropods

I’m eager to find some more rare specimens (not necessarily just Ulugh but also Cerato and others), but it’s proving to be a challenge for sure

Serration count isn't everything. And saying that is the end all be all is very misleading.
