Tyrannosaur tooth, rex or albertasaurus?

[wd7]

found this tooth near Huxley, Alberta, just north of Dry Island Buffalo Jump park. I was fairly high in the canyon, I would say within 1/3 or 1/4 of prairie level, which is why im not 100% sure if I was lower Scollard or upper Horseshoe Canyon formation, and hence whether it's a rex or albert tooth.

 

CH: 5.2cm, CBL: 2.4, CBW: 1.9, AL:5.5, Mesial denticles: 9/5mm, Distal denticles: 8/5mm.
