keithmegalodon Posted October 31, 2015 Share Posted October 31, 2015 Hello TFF, I started looking for T rex teeth these past few months and came upon this juvenile T rex tooth. It has got no visible serrations based on the photo. I asked the seller if he could give me some clearer photos of the specimen. I hope this is really a rex tooth! Would like to ask your opinion if it looks like a t rex tooth or not. Thank you all in advance for sharing your opinion! Link to comment Share on other sites More sharing options...
keithmegalodon Posted October 31, 2015 Author Share Posted October 31, 2015 The seller told me it is a juvenile trex or a larger nano left maxillary tooth. Link to comment Share on other sites More sharing options...
Troodon Posted October 31, 2015 Share Posted October 31, 2015 (edited) What can you tell us about the tooth. Size and locality of where it was found. Edit: agreed better photos are needed, need one of the bottom to see the profile of the base Edited October 31, 2015 by Troodon Link to comment Share on other sites More sharing options...
keithmegalodon Posted October 31, 2015 Author Share Posted October 31, 2015 Sorry troodon but i dont know the locality of the specimen yet but I do know that its 3.8cm tall. Link to comment Share on other sites More sharing options...
Troodon Posted October 31, 2015 Share Posted October 31, 2015 Sorry cannot help you at this time with the information you've provided. A geologic formation, locality as well as additional pictures is needed to help you with an ID. Be glad to help with the additional info. If the seller does not have or is unwilling to provide you this information I would walk away from the purchase. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted October 31, 2015 Share Posted October 31, 2015 The fact that serrations aren't highlighted in the photo seems like a red flag to me. Link to comment Share on other sites More sharing options...
fossilized6s Posted October 31, 2015 Share Posted October 31, 2015 I am far from an expert on any matter regarding Dino material. But in my opinion I would say no, this is not a T-Rex tooth. No serrations=no trex. It seems more of a round tooth, like a Spinosaurus (but it's not that either). ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Troodon Posted October 31, 2015 Share Posted October 31, 2015 Let me clarify the ID. This is a tyrannosaurid tooth. Only issue is what species and it will require the info requested in my post to determine that. Serrations size are undetermined but worst case they are worn but may not be needed for an ID, Link to comment Share on other sites More sharing options...

Only issue is what species and it will require the info requested in my post to determine that. Serrations size are undetermined but worst case they are worn but may not be needed for an ID, I'm not so sure of that even. The interior structure exposed by the break at the lower right seems off to me. Does it vary that much ? Link to comment Share on other sites More sharing options...
Troodon Posted November 1, 2015 Share Posted November 1, 2015 That's a typical break on a theropod tooth Link to comment Share on other sites More sharing options...
Rockwood Posted November 1, 2015 Share Posted November 1, 2015 That's a typical break on a theropod tooth In mine the layer with a longitudinal texture is thinner and the bulk of the interior has more of a radial make up. Link to comment Share on other sites More sharing options...
Agos1221 Posted November 2, 2015 Share Posted November 2, 2015 (edited) I own a T-Rex tooth and a defining feature aside from its length and geologic strata of origin that exclusively contains T-Rex as a tyrannosaurid is the D shape of the tooth in side view along with the size/count of serrations per cementer (10 - 15) for T-Rex.
