It is hard to deciede how Tyrannosaurs evovled. I have been trying to figure this out for days. I have come to a cunclusion that Tyrannosaurs evolved in asia and then some crossed a land bridge into North America where things like Albertosaurus evoled into Tyrannosaurs and other tyrannisauridae evolved into Tarbosaurus but how were they so similar???
