Tooth..T Rex or other

[billyatom]

I have a tooth that i'd always thought was T Rex.  Now that i've found this forum, I've some question about it.  I did a serration count and it averages 22/cm on both proximal and distal.  I found the tooth in 1969 in the Montana Milk River Badlands just a couple miles south of Alberta.  I also found a phalange from which I

thought was a T Rex too.  I can put that in another post.  The scale is in MM in the photo.

Sorry but if you  collected this in Hill County you are in the Judith River Formation which does not have T rex's.    Rex's are in the Hell Creek Formation which is further south and east.    It is a Tyrannosaurid but identification beyond that is impossible.  Two candidates possible is Daspletosaurus and Gorgosaurus.   Albertosaurus is possible but from younger strata.   Still very nice.
