Labels:text | font | screenshot | paper | document OCR: Well-developed senses of sight, smell, and hearing were crucial to the long-running success of the dinosaurs. Dinosaurs used these senses daily for survival in their hostile world. SENSES AND THE BRAIN Dinosaurs that were active hunters tracked prey by noises and scents. Plant-eating dinosaurs that lived in herds protected themselves and their young by watching, listening, and sniffing the air for predators. The sensors for sight, hearing, and smell were all located in the head at the eyes, ears, and nose, with a direct link through nerves to the brain. Nerve signals flowed continuously along the nerves to the brain. In the brain, nerve signals were interpreted as images, sounds, and smells, keeping the dinosaur constantly aware of what was happening around it. QUALITY OF VISION Modern plant-eaters, such as cattle and rabbits, have eyes located on either side of the head. The majority of dinosaurs were plant-eaters, and most of them also had eyes located on either side of the head. As a result they had a good, all-round view and could keep a lookout over a wide area for approaching predators. Many flesh-eating dinosaurs, like modern predators such as lions and eagles, had eyes that faced forward. They saw a predominantly forward view, just as humans see, and this enabled them to judge distances accurately when chasing prey.
