Bissekty jaw section


Fossil'n'Roll

Recommended Posts

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.

I know nothing about turanoceratops except that it sounds like a ceratopsian.  This looks hadrosaurian.

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

Perhaps a wild guess but don’t therizinosaurs have similar tooth batteries?

Happy hunting,

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!

They are actually very different more like Thescelosaurus but with very tiny teeth

Here is a partial dentary from one in the Bissekty Fm
