It will be difficult to separate anything from _Aublysodon mirandus_, since
that type of tooth is found on two continents, in Campanian and Maastrichtian
strata, and in association with postcrania belonging to at least two (if not
more) distinct tyrannosaurid genera. It is diagnostic at best to subfamily
level, or even worse, to family level if it turns out that juvenile
tyrannosaurine premaxillary teeth may have unserrated carinae.
