Nanotyrannus or juvenile Tyrannosaurus Rex ?

[M3gal0don_M4n]

I found this while I was looking at teeth. It is labelled as “Nanotyrannus/juvenile Tyrannosaurus Rex”. I was wondering if you could help, as a tooth from a Tyrannosaurid (I’m not fussy) is high on my list of wanted fossils. I need a response in the next 4 days

1st, what state and county did it come from?  What formation is it believed to be from?  

 

2nd, can you please post a clear pic of the base?  The one shown is 90% white background and tooth is basically a black shadow.

[M3gal0don_M4n]

It is from Hell Creek, particularly Montana. In answer to your second question, I sadly cannot provide any more images as these were the ones that were shown.

I remember reading that Nanotyrannus and Tyrannosaurus Rex have different shaped bases, is that true? If so, can I have some reference images? 

[Brevicollis]

Yes, thats true. Nano teeth have a pinch at the base, while Rex doesnt have them. But even these can variy after tooth position, or age of the animal it belonged to. I'm kinda new to the Nano/Rex scene, so I cant really help here further.

I have found a T-Rex tooth that appears the same from the base

Hi, the seller should provide better images.
From what we can see, the tooth is (a) slender with (b) a pointed tip and (c) an rectangular base.
So with the images at hand, it looks like a Nanotyrannus tooth.
Concerning the other base you have shown, it has an oval shape not a rectangular / box-shape.

Here a link to Troodon's  awesome guide:

Where in Montana is particularly important.

[M3gal0don_M4n]

Sadly, I do not have access to that information and I would only inquire if I decide I am more serious on it.

Without it all you can really call it is Tyrannosaurid unless other pictures very clearly indicate nano.
