Where does it stand?

Well, several years ago, some teeth were discovered in China credited to a new species, Tyrannosaurus zhuchengensis. However, folks said it was nothing and ignored that claim for a new species. Now, a skull that doesn't match any known tyrannosaur has been discovered. They'd like to call it Zhuchengtyrannus magnus -- but is this just more evidence of T. zhuchengensis? If so, that's the name it keeps.
