Captcrunch227 Posted October 17, 2018 Share Posted October 17, 2018 (edited) MORE PICTURES IN LOWER POSTS! Howdy everyone! I picked up this tooth not long ago and am curious if it is either nanotyrannus or T-Rex? Tooth comes from the hell creek formation. It was sold to me as nanotyrannus but it seems somewhat bulky and thick at the bottom so I thought I'd ask. Tooth is roughly 1-3/8" long in a straight line. Thanks for the help everyone!

DatFossilBoy Posted October 17, 2018 Share Posted October 17, 2018 Better pictures or different angles of the tooth would be needed for a clear ID. If I was to choose between the two I would say T. rex since it’s too fat to be a nano but better pics are needed. regards Link to comment Share on other sites More sharing options...

Runner64 Posted October 17, 2018 Share Posted October 17, 2018 Hard to tell because the pictures are blurry and out of focus. I think it is Nano because it is narrow and compressed in cross-section in the first picture. Link to comment Share on other sites More sharing options...
mburkett Posted October 17, 2018 Share Posted October 17, 2018 Hmmmm. I’m kind of changing my mind. The base doesn’t look as compressed as the first pics you posted. Really need a clear pic straight on of the root/base Edit: I got your post mixed up with another post, which is why I wrote I’m “changing my mind”. But here’s my opinion anyway, lol Link to comment Share on other sites More sharing options...
mburkett Posted October 17, 2018 Share Posted October 17, 2018 Here’s my large Nano tooth. It’s thick, but you can tell it’s Nano and not Rex because of the compression at the base Link to comment Share on other sites More sharing options...
mburkett Posted October 17, 2018 Share Posted October 17, 2018 Looking at the base of your tooth a little more, it does appear to have the constriction/compression. I’m still saying it’s Nano Link to comment Share on other sites More sharing options...

indominus rex Posted October 17, 2018 Share Posted October 17, 2018 To me it looks more like a Trex tooth. Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...
mburkett Posted October 17, 2018 Share Posted October 17, 2018 It’s still hard to tell. The first pic you posted shows constriction on the left side of the tooth. Here’s one of my Rex teeth. You can see it doesn’t have this. I’m fairly sure your tooth is Nano. Link to comment Share on other sites More sharing options...
Runner64 Posted October 17, 2018 Share Posted October 17, 2018 Thanks for the photo, I'm thinking Nanotyrannus Link to comment Share on other sites More sharing options...

Forgive my ignorance please. I've had zero luck finding any information on the differences between the two, and it was not for lack of trying. Could you enlighten me please as to what I'm looking for? When you say constriction is it running the length of the tooth or just at the base? Thanks so much for your help!

mburkett Posted October 18, 2018 Share Posted October 18, 2018 No need to be sorry. @Troodon has a good post on the difference between the teeth of these two species on this site. I think it’s @Andy who has a HUGE Nano tooth where you can also see the indentations at the base. I’m trying to upload pics of what I’m talking about, but evidently they’re larger than 3.95 MB, so I can’t. Basically, Nano teeth have a )( at the base, whereas Rex doesn’t. Here’s a terrible drawing of what I’m trying to say. This is looking directly at the base of the tooth vertically. It doesn’t run the length of the tooth. 1 Link to comment Share on other sites More sharing options...
mburkett Posted October 18, 2018 Share Posted October 18, 2018 But again, there’s a debate on if Nano and Rex are the same species, with Nano being a juvenile Rex. I’m in the camp that they’re two different species. Hopefully Baby Bob and the Dueling Dinosaurs can answer the question once and for all 1 Link to comment Share on other sites More sharing options...
Captcrunch227 Posted October 18, 2018 Author Share Posted October 18, 2018 @mburkett thank you so much that was incredibly helpful. That is good to know. The base on this tooth has somewhat of a construction on one side (very slight though) and the other side doesn't appear to have that constriction, although on that side a good chunk of the outer enamel is missing at the base. What is getting me on this tooth though is how thick the base is. I expected the tooth to be more dromaeosaur like (similar to the cause of confusion at times with nano and dakotaraptor teeth). That's what caused me to post this, the bulbous shape and width at the bottom seemed out of character with what very very little I knew of nano teeth Link to comment Share on other sites More sharing options...
mburkett Posted October 18, 2018 Share Posted October 18, 2018 It IS a relatively beefy tooth, but I’m pretty confident it’s Nano. Dakotaraptor is pretty easily distinguished from Nanotyrannus bc the former’s denticles are differently-sized anterior and posterior. The posterior serrations are bigger and this should be evident to the naked eye. Identifying teeth definitely can be tricky. Locality is a must!

Captcrunch227 Posted October 18, 2018 Author Share Posted October 18, 2018 I definitely appreciate you taking the time to help me out. I really appreciate it! Either way it's a win win. It's either my first nano tooth that I got a pretty good deal on, or it was a t-rex tooth that I absolutely stole haha Link to comment Share on other sites More sharing options...
mburkett Posted October 18, 2018 Share Posted October 18, 2018 No problem. It’s a neat tooth! Link to comment Share on other sites More sharing options...
