Albertosaurus tooth placement

[Alex Eve]

Hello. I found this 7.5 cm Albertosaurus tooth in the Bleriot Ferry area of the Horseshoe Canyon Formation last month. Based on the wear mark on the end, whereabouts would the tooth be placed within the mouth? (top or bottom?). Is it possible to tell?

First off, great tooth!  And a very warm welcome to the forum! Dinosaurs aren't my area but some experts will be along soon.

Thanks!

Sometimes you can by looking at the shape of the base.   So can you take a straight in photo of base and posterior carina.  Thanks

Sure. What’s left of the root is somewhat rectangular shaped with round edges

If its rectunglar good chance its a Maxillary tooth.  Nice find BTW

Sweet! While you’re here, this is another Albertosaur tooth found in the same area. Based on its size (5cm), base shape, and wear mark, whereabouts would this one be placed?

Another nice find thats an dentary tooth probably more distal than anterior

Awesome! I was thinking distal too because of the wear mark. Thanks again!
