Quote by Michael Crichton

“Why did Dodgson just stand there like that? That's not the way to act around predators. You get caught around lions, you make a lot of noise, wave your hands around, throw things at them. Try to scare them off. You don't just stand there." "He probably read the wrong research paper. There's been a theory going around that tyrannosaurs can only see movement. A guy named Roxton made casts of rex braincases, and concluded tyrannosaurs had the brain of a frog." "Roxton is an idiot. He doesn't know enough anatomy to have sex with his wife. His paper was a joke." "What paper?" "Roxton believed that tyrannosaurs had a visual system like an amphibian: like a frog. A frog sees motion but doesn't see stillness. But it is quite impossible that a predator such as a tyrannosaur would have a visual system that worked that way. Quite impossible. Because the most common defence of prey animals is to freeze. A deer or something like that, it senses danger and it freezes. A predator has to be able to see them anyway. And of course a tyrannosaur could.”
