Nanotyrannus (meaning "dwarf tyrant") is a doubtful genus of tyrannosaurid dinosaur. They may be juveniles of Tyrannosaurus or a similar genus.[1]
Only two or three specimens are known. They are from the end of the Upper Cretaceous, 67 million years ago. The first alleged specimen was found in Montana in 1942. It was thought to have been a Gorgosaurus, but it was reclassified in 1988.
