Lance formation tooth question

[FF7_Yuffie]

Hello, anyone able to help with this one?

 

Going through my old "fossil" folder, I found this one I got 10 years ago bought as "Albertosaurus" from Lance Formation.

 

Now, looking online I'm seeing Albertosaurus as not being from Lance. Indeed, only valid Tyrannosaur from there is looking like Rex

 

Would this be better labelled as Undetermined Tyrannosaur, a T rex, or has Albertosaurus actually been found there?

 

Apologies for pictures. The actual fossil is in storage box at my UK home, I'm in Taiwan and wont be going back there until COVID is over. So, hopefully these two older pics are enough to narrow it down.

 

There are some serrations, which I believe seperates it from the juvenile teeth usually sold as Aublysodon?

There are two Tyrannosaurids in the Lance,  T rex and Nanotyrannus.  Need to see how wide and base but it could be either at 23mm but would not lean toward Trex

Cheers

 

That'll be one to repost pics of the base when I get back to England and can take fresh pics.

 

But, I'll switch the excel file label on my computer I've got from Albertosaurus since thst one can be ruled out.

 

Thanks for taking a look.

This looks robust enough from here to be  Tyrannosaurus.

I'll be sure to update whenever I manage to get home and try to get a more definite ID whether Nano or Rexy. For now, at least, can update my excel sheet to remove Albertosaurus.

 

Thanks for help.
