"Keep absolutely still. Its vision's based on movement."—Alan Grant

Tyrannosaurus Rex was a large predatory dinosaur. This article deals with the creature seen in the Jurassic Park franchise, and may have some information that doesn't correspond to what information is available on the actual dinosaur.

Behavior
Tyrannosaurs are apex predators and as such spend a lot of time following game trails. They seem to prefer to ambush prey animals, and it was once thought that this was possibly because of their motion sensitive eyesight, which has since been disproven. It was once theorized that most prey animals freeze when afraid because the tyrannosaur supposedly lacked the ability to see stationary prey. In actuality, Tyrannosaurs have excellent binocular vision, though is seems that it is difficult to see moving prey in very poor lighting conditions. The Tyrannosaurs are not random killers, however, and are less likely to attack when full. Tyrannosaurs are known to pair off during mating, and both parents will remain with their offspring during its growth, exhibiting very powerful parenting and protective instincts, going to great lengths to ensure an infant's safety. However, when they are fully grown and independent they are more solitary, and only interact when mating or rearing young. They also bring small live prey to their young, teaching them how to kill live prey for themselves. Tyrannosaurs are territorial by nature, and will attempt to drive away or kill anything that might be deemed dangerous, whether animate or not.
