BonuFrailman Posted October 12, 2020 Share Posted October 12, 2020 Hi all, I bought this tooth recently on an auction site and was wondering what you folks think. The seller bought it at Tucson Fossil show but lost the ID card with the Formation on it, so the locale is missing. Info on the tooth: 1 inch long Supposedly from Madagascar Link to comment Share on other sites More sharing options...
Troodon Posted October 12, 2020 Share Posted October 12, 2020 Without a locality its an indeterminate theropod. Dinosaur deposits in Madagascar can be from mid jurassic to Late Cretaceous 2 Link to comment Share on other sites More sharing options...
Anomotodon Posted October 12, 2020 Share Posted October 12, 2020 I believe I was the one who traded this tooth to that seller... It is a theropod from Bissekty formation, Uzbekistan. 1 The Tooth Fairy Link to comment Share on other sites More sharing options...

Don’t beat yourself up on this tooth, I particularly like the quality of it 1 Link to comment Share on other sites More sharing options...

Troodon Posted October 12, 2020 Share Posted October 12, 2020 The shape and size of the tooth suggests it might be the tyrannosauroid Timurlengia but when you receive the tooth would suggest a serration count to see if it supports that assignment Link to comment Share on other sites More sharing options...

I found a previous listing of this tooth from the auction site that listed this could indeed be a carcharodontosauridae tooth. Link to comment Share on other sites More sharing options...

I don't have a microscope, only a loupe. Link to comment Share on other sites More sharing options...
Troodon Posted October 23, 2020 Share Posted October 23, 2020 The most important item in a identification is a solid provenance without it its very difficult to identify. Carcharodontosaurids are not known from the Bissekty fm. The attached illustration shows you where to take the density measurements. A loupe and scale may work it just harder to see and count. Another approach is to take a closeup photo of the carina next to a scale and blow it up. Link to comment Share on other sites More sharing options...
