(pronounced NAN-oh-tie-RAN-us) Nanotyrannus (meaning "tiny tyrant") was a bipedal meat-eater, a theropod from the late Cretaceous Period (68-65 million years ago). It was about 16 feet long (5 m), had a large head, long legs with three-toed feet, short arms with two-fingered hands, a short, thick neck, large jaws with sharp teeth, narrow hips, and a slim tail. Nanotyrannus was a tyrannosaurid dinosaur named by paleontologists M. Williams, R. Bakker, and P. J. Currie in 1988 from a skull only 22 inches (57.2 cm) long found in Montana, USA in 1942. It may be a juvenile Tyrannosaurus rex. The only known skull has been CAT-scanned by Bakker. He thinks that Nanotyrannus is an adult, but many other paleontologists, like Thomas D. Carr disagree, and think the Nanotyrannus is a juvenile T. rex.

Personally, I feel that the upper jaw is a little too low, and the whole design too slender for this to be the same species as Tyrannosaurus rex - if you look at the skull of Nanotyrannus, and then at one from a Tyrannosaurus, you'll see what I mean. I agree fully with Bakker on this one.

Anyway, nice drawing of the skull, though I think the skin texture in the life drawing leaves something to be desired.
