Hello! So, as you may know, there's been a lot of controversy over whether Tarbosaurus and Tyrannosaurus are the same genus. Any thoughts? Are they closely spaced on the Tyrannosaur family tree or did Tarbosaurus convergently evolve like Tyrannosaurus from the asian Tyrannosaur lineage instead of immigrants from america? Thanks.

P.s. I know all Tyrannosaurs are decended from asian lineages, but I want to know whether Tarbosaurus was descended from the late cretaceous north american Tyrannosaurrs or late cretaceous asian Tyrannosaurs.

P.p.s. I'm sorry if I made this to complicated.
