A rare Nanotyrannus lancensis tooth from the Hell Creek Formation, South Dakota, USA. [No Reserve]

PROVENANCE:
From an old Boston, USA, collection.

FOOTNOTES:
The name Nanotyrannus means 'tiny tyrant' but at approximately 17 feet in length, Nanotyrannus was not exactly tiny, just small in comparison to its fellow tyrannosaurids. Its best known relative is the larger Tyrannosaurus rex. Like all tyrannosaurs, Nanotyrannus was a bi-pedal carnivore. It had narrow hips, a slim tail, long legs with three-toed feet and short arms with two-fingered hands. Its short, thick neck carried a large head with jaws of sharp curved and serrated teeth. It is theorized that it weighed less than 1000 pounds. The tooth has had the tip restored.
