Tyrannosaurus rex, the "Tyrant  Lizard King," is the most famous  dinosaur in existence, being  represented in art, literature, entertainment, etc. With a  maximum length exceeding twelve  meters and a height of over three meters, this creature towered over humans and many other animals as  well. Its growth started and ended slowly, but Tyrannosaurus  experienced a growth spurt during  its teenage years. The result was  the giant creature known and loved  today. However, like many other  tyrannosaurs, Tyrannosaurus died  shortly after reaching maturity and their infants often died naturally in the volatile world of the  Cretaceous.   Living in the Maastrichtian age,  just before the extinction of the  dinosaurs in the Cretaceous,  Tyrannosaurus was among the last  great non-avian dinosaurs to roam  the Earth. In fact, it is the last  known member of its family Tyranno- sauridae. It lived across what is  now North America in warm and humid  climates alongside a plethora of  herbivorous animals and small  theropods. It commonly preyed upon  famous herbivores such as  Triceratops and Edmontosaurus. Its  hollow bones allowed it to move  quickly and its robust, blade-like  teeth permitted it to rip into prey,  mutilating any allegations that it  may be a simple scavenger.
