In the very famous movie Jurassic Park, there is a scene where the tour crew is attacked by a T-Rex tyrannosaur under a thunderstorm. In that scene, Dr. Alan Grant, a paleontologist shouted: “Don’t run, it can’t see us if we don’t move.” In the movies that seems to work, but in reality can we fool a T-Rex just by not being quiet? Although scientists were not able to conduct actual tests, with their knowledge of archeology and biology they managed to explain the truth.
>>> Tyrannosaurs have ten thousand times more bite force than humans
You may not know that the movie Jurassic Park has taken data on dinosaurs from previous research projects. However, due to the lack of science and technology and knowledge at that time, the assessment of the extinct dinosaurs was not accurate.
In 1993, professor Kent Stevens at the University of Oregon conducted a study called DinoMorph , which digitally modeled extinct dinosaurs for real research.
He successfully built models of two famous carnivorous dinosaurs, T-Rex and Velociraptor. Through these models, he continued to conduct vision and vision studies of these two dinosaurs.
In 2006, Stevens published the results of his research and evaluations of the T-Rex’s visual abilities with different subjects. He said the T-Rex’s vision is even better than what we previously evaluated . According to research, the eyes of these carnivorous dinosaurs closely resemble those of modern birds of prey. Even the sight of a T-Rex is greater than that of a hawk (more than 55 degrees).
However, wide vision is not all, eyesight is the important issue for predators. Stevens continues to conduct research with animals that are closely related to dinosaurs such as chickens, crocodiles and other reptiles. Judging from the eyesight of these animals with the eyeball size of a T-Rex. The results showed that a T-Rex has four times the eyesight of an eagle or a crocodile, and 13 times higher than that of a human. They can clearly see an object at a distance of 6km, while humans can only see clearly at a distance of less than 1.6km.
Concluding his research, Professor Stevens said that the eyesight of the tyrannosaurs was surprising, they could clearly see objects of prey even when they were running or standing motionless.
Not only are their visas amazing, their sense of smell and hearing are also well-developed . The olfactory area and large sensory cells give it a sense of smell similar to today’s vultures. They can smell corpses from several kilometers away. Therefore, as long as you sweat and pant out of fear, a T-Rex can detect you before it sees you.
With such developed senses, they are the most dangerous predator ever. So you won’t have a chance of survival if you have to face a real-life T-Rex.
