Buffalo Jake Posted August 18, 2017 Share Posted August 18, 2017 Good afternoon all, I wanted to get some opinions on determining if a tooth I am thinking about purchasing is either a T-Rex, or a Nanotyrannus tooth. I will post some pictures of the tooth, and supply what information I know about it. • The tooth is 1" long, with a round cross section. • Robust serrations. • Found in the Hell Creek Formation, Powder River County, Montana. Due to the round cross section and serrations, I have been leaning towards classifying it as a T-Rex tooth. I'm very interested to hear member thoughts.

Miocene_Mason Posted August 18, 2017 Share Posted August 18, 2017 I think @Troodon must be preoccupied, as he has indeed been absent for a month. So we may be on our own for this one. To start off, Nanotyrannus is thought to be a young tyrannosaurus by most, and the main difference concerns the number of teeth. I think both have virtually indistinguishable teeth (although maybe someone knows a way). It does look like an authentic and rather nice tyrannosaur tooth. 1 “...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...
Buffalo Jake Posted August 18, 2017 Author Share Posted August 18, 2017 My Nanotyrannus teeth have more of a rectangular cross section, and this tooth has a round cross section. Hence the reason I was leaning towards T-Rex. Link to comment Share on other sites More sharing options...

-Andy- Posted August 19, 2017 Share Posted August 19, 2017 @hxmendoza I am leaning towards T-Rex as it does look robust. Let's see what others say. Here's my tooth that was initially sold as Nanotyrannus but later ID-ed as Rex. 3 hours ago, WhodamanHD said: To start off, Nanotyrannus is thought to be a young tyrannosaurus by most, and the main difference concerns the number of teeth. I think both have virtually indistinguishable teeth (although maybe someone knows a way). It does look like an authentic and rather nice tyrannosaur tooth. Nope. T-Rex vs Nanotyrannus is still a hot topic of contention. But I can assure you the majority of dealers do put a distinction between Rex and Nano, with Rex fetching several times the price. Here are my teeth. Nano has a narrower cross section, and is much less robust than Rex. 3 Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...
Buffalo Jake Posted August 19, 2017 Author Share Posted August 19, 2017 Those are some awesome teeth you have Andy! Here are a couple Nanotyrannus teeth I have. Link to comment Share on other sites More sharing options...
hxmendoza Posted August 21, 2017 Share Posted August 21, 2017 It's an anterior tooth. Though small, it has more of the proportions of a juvenile T. rex tooth. Anterior Nanotyrannus teeth can be more noticeably inflated than the lateral teeth, but this one has a pretty robust round cross section, so I'm going to go with juvenile T. rex tooth. It's teeth like these that I think academic paeontologists overlook in the debate between Nanotyrannus and T. rex. Juvenile rex teeth that are noticeably robust compared to Nanotyrannus teeth from the same or fairly similar jaw position. 1 Link to comment Share on other sites More sharing options...

Runner64 Posted August 23, 2017 Share Posted August 23, 2017 Try posting a picture of the base, that may help in the ID. Leaning towards Rex as well because if the robustness of the tooth. Link to comment Share on other sites More sharing options...
Buffalo Jake Posted August 23, 2017 Author Share Posted August 23, 2017 Thanks for all of the replies to this topic. However, I procrastinated too long and missed out on that tooth. Lesson learned haha.... Link to comment Share on other sites More sharing options...
