About Nanotyrannus:

Nanotyrannus lancensis is a small tyrannosaurid theropod known from the Late Cretaceous Lance and Hell Creek Formations. Its exact identity remains one of the more debated topics in paleontology: some researchers consider it a valid, smaller-bodied genus distinct from Tyrannosaurus rex, while others argue known specimens are simply juvenile T. rex. Nanotyrannus teeth are more slender and more numerous in the fossil record than mature T. rex teeth, and they're prized by collectors for their fine, blade-like serrations.
