Praefectus Posted November 10, 2020 Share Posted November 10, 2020 Hello. I was wondering if anyone could help me identify this tooth from a friend’s collection. It comes from the Bissekty formation in Uzebekistan. It is 1.81 inches (4.6 cm) long. I think fish, pterosaur, crocodylimorph, or aquatic reptile are potential identities. Please let me know if more pictures are required. Thank you for your help. Link to comment Share on other sites More sharing options...
Runner64 Posted November 10, 2020 Share Posted November 10, 2020 I don’t think it’s pterosaur or dinosaurian. Not sure what croc teeth look like from there either but doesn’t look fat enough for croc. I’m also assuming the tooth is too large for any fish. I do see there is a pleisiosaurid indet. Described from the Bissekty Formation. 1 Link to comment Share on other sites More sharing options...
Troodon Posted November 10, 2020 Share Posted November 10, 2020 Hans-Dieter Sues and Alexander Averianov have authored a large number of papers from this deposit. So my suggestion is to contact one of them on this unusual tooth. Hans-Dieter is the Curator of Vertebrate Paleontology at the National Museum of Natural History of the Smithsonian Institution so my guess is you have a better shot emailing Alexander.

Troodon Posted November 14, 2020 Share Posted November 14, 2020 Great, it did look a bit like one but now you have a definitive answer. Good to know he's a resource for future questions with their material. Link to comment Share on other sites More sharing options...
