BellamyBlake Posted March 14, 2021 Share Posted March 14, 2021 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 Link to comment Share on other sites More sharing options...
BellamyBlake Posted March 14, 2021 Author Share Posted March 14, 2021 Second one is 0.88" x 0.55" Link to comment Share on other sites More sharing options...
Troodon Posted March 14, 2021 Share Posted March 14, 2021 Need to get a feel of serration density at midline to call these Timurlengia Link to comment Share on other sites More sharing options...

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

Troodon Posted March 14, 2021 Share Posted March 14, 2021 Like to see what those 5mm say. Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
Troodon Posted March 15, 2021 Share Posted March 15, 2021 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 Link to comment Share on other sites More sharing options...
Troodon Posted March 15, 2021 Share Posted March 15, 2021 If it was a tyrannosauroid then it would be Timurlengia so its Theropod indet. 1 Link to comment Share on other sites More sharing options...
