Nanotyrannus= "tiny tyrant"
First off I want to show you the part of this dinosaur that i found most interesting. Enjoy! This is a Nanotyrannus' tooth. It may just look like a normal tooth, but if u look closer at the tooth... See what I see? The tooth has little teeth on the side. Which probably helped it grip onto its prey. I haven't found exactly what the tiny teeth on the tooth was used for but i'm just taking a guess. Keeps you wondering doesn't it? Having been related to the t-rex family, this dinosaur was rarest, the fastest, and the smallest. Unlike it's closest relative, the t-rex, it has a small, thin body. It has narrow hips, a slim tail, long slim legs with 3 toed feet, short arms with two fingered hands and a thick, short neck carried a large head with large, powerful jaws.
