Fossil'n'Roll Posted April 2, 2018 Share Posted April 2, 2018 I recently bought this 3" jaw section from the Bissekty Formation. The seller had it listed as Turanoceratops. I was a little skeptical since I knew at least one Hadrosaur is found there and small Hadrosaur and Ceratopsian jaw sections I've seen look very similar to me. I also found this exact fossil in another thread (below), where @Troodon said it and several others looked like Hadrosaurid jaws. Is it definitely from a hadrosaur or could it be Turanoceratops? I'm happy either way but would like to know what to label it. Link to comment Share on other sites More sharing options...
Peat Burns Posted April 2, 2018 Share Posted April 2, 2018 I would have called that hadrosaur. Let's see what @Troodon and @jpc say. Link to comment Share on other sites More sharing options...
jpc Posted April 3, 2018 Share Posted April 3, 2018 I know nothing about turanoceratops except that it sounds like a ceratopsian. This looks hadrosaurian. Link to comment Share on other sites More sharing options...
Troodon Posted April 3, 2018 Share Posted April 3, 2018 Agree with jpc. We have no dentary material from the Bissekty Fm on either species to compare against but still can make a call. Like I said in the previous post there is currently one hadrosauroid described Levnesovia transoxiana but its unknown if others will be described. FYI here is a typical hadrosaur jaw to compare against Cerstopsian are deeper Link to comment Share on other sites More sharing options...
Miocene_Mason Posted April 3, 2018 Share Posted April 3, 2018 Perhaps a wild guess but don’t therizinosaurs have similar tooth batteries? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Fossil'n'Roll Posted April 3, 2018 Author Share Posted April 3, 2018 Quote 5 hours ago, Troodon said: Cerstopsian are deeper That would make sense with a double root. It definitely looks more like that Hadrosaurus jaw. I also just found this picture of a Corythosaurus excavatus jaw that looks very similar. I guess I'll label it Levnesovia transoxiana until another hadrosaur is described. Thanks! Link to comment Share on other sites More sharing options...

They are actually very different more like Thescelosaurus but with very tiny teeth Here is a partial dentary from one in the Bissekty Fm Scale is 1 mm Link to comment Share on other sites More sharing options...
