I have here two theropod teeth from the Bissekty Formation of Uzbekistan. I believe they're Timurlengia. Can that identification be made?

 

First one is 1.08" long and 0.55" wide

Need to get a feel of serration density at midline to call these Timurlengia

Thank you. They're both pretty unserrated. The smaller one has maybe 5 mm worth, distal carina towards the base. They're both Theropod indeterminate then?

Like to see what those 5mm say.

Smaller one has 4mm of serrations on the distal carina, towards the base of the crown.

 

19 Serrations / 4 mm = 4.75 / mm

 

I also found serrations on the larger one, distal carina, middle.

 

16 Serrations / 5 mm = 3.2 / mm

 

I hope this helps

The paper identifies 3 to 5 per mm midline on mesial edge and slightly fewer on the distal.  So if the one tooth had 4.75 that's pretty dense and should be Timurlengia.  Same with the other tooth most likely one but not certain.  If you want positive ID's it's all about preservation.

Thank you Frank. I'm pretty satisfied with the density on the 4.75 / mm smaller tooth and I'll label it Timurlengia. As far as the other one goes, would the most accurate ID be Tyrannosauroid or Theropod indet? I know a Dromaeosaurid exists there too

If it was a tyrannosauroid then it would be Timurlengia so its Theropod indet.

Thank you very much. Theropod indet. it is!
