X.Rex Posted September 27, 2016 Share Posted September 27, 2016 Hello dear fellow fossil lovers Recently my interest of collecting stuff has shifted to dinosaur teeth, and having a decent sized T Rex tooth in my collection is a must thanks to my OCD. Dinosaurs has fascinated me ever since I was a kid. So after I sold one of my beloved guitars, here it is. I counted the serrations on both side, about 18-22 per cm so should confirm it is pulled out from an adult T.Rex based on what I have read. The info says it was unearthed from Lance Creek fm. Being a complete noob on dino fossile Please let me know what you guys think, does this look like the real deal to you? Link to comment Share on other sites More sharing options...
Darktooth Posted September 27, 2016 Share Posted September 27, 2016 I am not very knowledgeable about dino stuff. But I will say that looks like one sweet tooth! Troodon oh Troodon were art thou now Troodon? I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

Troodon Posted September 28, 2016 Share Posted September 28, 2016 Nice tooth and definitely a tyrannosaurid. What is the length of the tooth? Can you take a straight in picture of the base Link to comment Share on other sites More sharing options...

I have been wanting one of these for a long time now....But way out of my budget..But I do have a scientific study cast of one of Stan's teeth and it does look real.

Troodon Posted September 28, 2016 Share Posted September 28, 2016 Wanted to make sure we are not looking at a large Nanotyrannus. Size, robustness coupled with your serration count clearly says Rex. A study I conducted with my teeth indicated for a 3" tooth you can expect serrations to be what 1.8-2/mm, exactly what yours is. Nice tooth and most likely a left maxillary one. 2 Link to comment Share on other sites More sharing options...

Lance and Hell Creek Formations most likely, thats where my favorite ones used to live Other than that Nemegt Formation would be another place I want to go look for dino teeth, but that's off the limit currently I guess Link to comment Share on other sites More sharing options...
Troodon Posted September 28, 2016 Share Posted September 28, 2016 I put this together for the teeth in those two formations 3 Link to comment Share on other sites More sharing options...
hxmendoza Posted September 28, 2016 Share Posted September 28, 2016 Definitely T. rex. In my opinion, it is not not robust enough labial/lingually to be from the dentary. So I agree with Troodon on it being a maxillary tooth. But I disagree on it being a left maxillary. It's a right maxillary. The posterior (distal) serrations are labially placed, and the anterior (medial) serrations are lingually oriented making it a right maxillary tooth. 1 Link to comment Share on other sites More sharing options...
