Tyrannosaurus: Tyrant Lizard King

I call her Suzann!

Tyrannosaurus was an apex predator that lived in what is now North America during the late Cretaceous before the mass extinction events roughly 65 million years ago.  
The largest member of the Tyrannosarinea family, Tyrannosaurus was a massive land predator designed to combat heavily armored prey such as triceratops, and could deliver approximately 3000lb of pressure in a single bite, enough to shatter bone and tear muscle with ease.
Tyrannosaurus was not built for speed, scientist think it could have run under 15km/h at top speed, meaning it was probably an opportunistic predator, scavenging kills whenever possible, but capable of hunting.
