9951 Tyrannosaurus           Discovered 1990 Nov. 15 by E. W. Elst at the European Southern Observatory.
Tyrannosaurus, a heavy bipedal dinosaur with a huge skull, long massive jaws and dagger-like teeth, was a most terrifying predator. Almost 14 meters long and 5 to 8 meters high, it lived during Upper Cretaceous times.
