(This is all from memory, so some of the spelling might be off)

Tyrannosauridae (= Deinodontidae)

Tyrannosaurus rex Osborn 1905           late Maastrichtian, western North
America
        (= Dynamosaurus imperiosus)
Nanotyrannus lancensis (Gilmore 1946)   late Maastrichtian, western North
America
        (?= juvenile T. rex?)
Albertosaurus? megagracilis Paul 1988   late Maastrichtian, western North
America
        (?= subadult T. rex?)
Tyrannosaurus bataar Maleev 1955        early Maastrichtian, eastern Asia
        (= Tarbosaurus efremovi, Gorgosaurus periculosus)

        (= Gorgosaurus novojilovi)

this one)

        (?= Deinodon horridus?)
        (since 1970 called Albertosaurus libratus, but at least some of the
characters used to unite libratus and sarcophagus are primitive for the
Tyrannosauridae)

        (?= Deinodon horridus?)
Aublysodon mirandus Leidy 1868          late Campanian, western North America
