Lance formation tooth

I found this  tooth in some matrix from the Lance formation in Wyoming. It doesn't have any serrations and it isn't as round as most of the crocodile teeth I have found. Any ideas? The scale is 1mm. Thanks.

Its a theropod Premaxillary tooth.  Good chance its Tyrannosaurid because of shape and lack of serrations.  Nice find.

I just ran across some pics of Tyrannosaurus Premaxillary teeth. Could it actually be from the King itself? What other therapods have teeth like this in the Lance?

I can't ID it but that's an awesome looking tooth. Congrats!

It could be Rex but more of a probability of being Nanotyrannus.   With that shape and lack of serrations hard to point to other theropods in the Lance.  Dromaeosaurid's would have at least on edge serrated and would be a bit curved and leaner.

Wow! My best find ever. Thanks.

I think the cross section view (first photo) also shows it to be too wide for a dromaeosaur.  I am on board for a small tyrannosaur.  Nice find.
