Nanotyrannus (meaning "dwarf tyrant") is a genus of tyrannosaurid dinosaur. They weren't a juveniles of Tyrannosaurus or a similar genus. The issue is decided and it has been proven that Nanotyrannus ruled the land, destroying every competing species and being the apex predator of it's time.

Only two or three specimens are known. They are from the end of the Upper Cretaceous, 67 million years ago.
