StefanD Posted November 28, 2018 Share Posted November 28, 2018 I've gotten a tooth and need help to identify it. He should comes from Wyoming (Hell Creek Formation) and is about 4,3cm (1.7 inches) tall. A geologist said, he might have come from a Carcharodontosaurus, but he does not come from North America. This is also the brown-black color. Carcharodontosaurus is native to Africa and would rather have sand color. However, I'm not a paleontologist^^. The Nanotyrannosaurus could it also be, if the origin is right. Of course, I also hope that it is not a fake, because on the inside, is a purple spot to see and I've never seen that in a fossil. By weight, it comes in any case to an original. It would be great if you could help me. (By the way, the Seller said it is a animal in family of the Tyrannosauridae) Link to comment Share on other sites More sharing options...
Raggedy Man Posted November 28, 2018 Share Posted November 28, 2018 @Troodon Can we get clear close up pictures of the serrations please? ...I'm back. Link to comment Share on other sites More sharing options...
Jaimin013 Posted November 28, 2018 Share Posted November 28, 2018 Not a Carcharodontosaurus tooth. Can we see the cross section base of the tooth (see example of my tooth below)? I am leaning towards nano because of the base of the first pic but I may be wrong and therefore it would be good to see a photo of this to help me better ID? It would be helpful if you could get serration count from the seller as well. Please also check out Troodon's post on identifying teeth from this location: 4 Link to comment Share on other sites More sharing options...

Jaimin013 Posted November 28, 2018 Share Posted November 28, 2018 Based on the photos, I would lean towards it being a Nanotyrannus tooth as opposed to a trex tooth. One thing I can say for certain is that it is definitely not a fake tooth. Lets see what other people think on the forum in relation to the ID! 2 Link to comment Share on other sites More sharing options...
Runner64 Posted November 28, 2018 Share Posted November 28, 2018 Definitely not a Carchardontosaurus tooth. Not sure what this geologist was thinking! Also, Carchardontosaurus only comes from Africa. Your tooth definitely looks like a Nanotyrannus and that is what I think it is because it is tyrannosaur and has a box shaped cross-section. It is too compressed to be a Rex tooth. Nice tooth too and very real! Link to comment Share on other sites More sharing options...
StefanD Posted November 28, 2018 Author Share Posted November 28, 2018 Many thanks for your help. I also thought, thats a Nanotyrannus. The seller wanted to say me, thats a rex, but i dont believed him, because its too small on base. The Rex tooth are more round in base or? Now i believe, i payed to much for it. How much would you mean, is the value? Link to comment Share on other sites More sharing options...

Unfortunately, not possible to value a tooth and we cannot discuss price on this area of the forum however feel free to message me on private message and I can let you know what I think? I have bought teeth in the past that are hugely overpriced but the more you research and the longer you collect fossils, the better you become at knowing when the asking price might be too high. 2 Link to comment Share on other sites More sharing options...
bcfossilcollector Posted November 29, 2018 Share Posted November 29, 2018 I wonder if the geologist was referring to Acrocanthosaurus a relative, I think, of Carcharodontosaurus. Remains of this particular dinosaur have been found in Wyoming. Tooth does look like a Nanotyrannus. 1 Link to comment Share on other sites More sharing options...
JohnBrewer Posted December 1, 2018 Share Posted December 1, 2018 Looks nanoish to me. @hxmendoza @LordTrilobite @jpc John Map of UK fossil sites Link to comment Share on other sites More sharing options...
jpc Posted December 2, 2018 Share Posted December 2, 2018 I would guess nano for this one. Just not robust like a rex. It looks like there is a seller out there giving out bad info. This is the second time recently that I have had to mention that there is no Hell Creek in Wyoming. Here we call the same beds Lance Formation. Since public education is part of what we do here... Lance Formation is the name of the latest Cretaceous dinosaur bearing rock unit in Wyoming. In MT, SD, ND it is called Hell Creek Fm. In CO it iis called Laramie Fm. 2 Link to comment Share on other sites More sharing options...
