Tyrannous Rex or T-Rex was primarily seen in the immensely popular movie “Jurassic Park”. This movie only made scientists think and conduct experiments on T-Rex vision and mobility. In the movie, a character, Dr. Alan Grant, said “Don’t move! He can’t see you if you don’t move”. There were many shreds of evidence that showed the efficiency of T-Rex’s eyes, but this dialogue in the movie made many scientists work on this claim and study the real fact about it.
In the further section, we will tell you the real facts about T-Rex vision. After that, all your doubts will be crystal clear.
To study the fact, Professor Kent Stevens at the University of Oregon initiated a project in 1993 named “DinoMorph”. Under this project, his main goal was to develop the simplified digital model skeletons of dinosaurs to recreate the tangible visualizations of them. In this project, Professor Kent Stevens conducted this experiment to see the parameters like a visual field, depth perception, and binocular range using tools like a laser pointer, glass plate, and taxidermic glass eyeballs. Through this experiment, he observed that the T-Rex has binocular range even more than that of Hawks i.e 55 degrees.
Even after all this, the question persisted that how good was T-Rex eyes in reality. He answered this question via an experiment where he took optics of the distant relatives of T-Rex such as eagle, chicken, and crocodile and corked them all in the T-Rex eyeball. After he studied this experiment, he concluded that T-Rex has 13 times better vision that of a normal human being. He even found that T-Rex can see the objects also if they are 6 kilometers away.
Scientists have often confused T-Rex’s vision with a Frog’s vision, but ultimately, after all the findings, it was seen that T-Rex has an excellent vision. And apart from its keen eyesight, T-Rex also has a great sense of smell and excellent hearing ability. In fact, they can smell dead things just like vultures smell their prey even if it is few kilometers away and all the credit goes to their large olfactory bulbs and nerves which are relative to their brain size.
The T-Rex has a speed of 17-25 miles/hour. The T-Rex’s arm only measures up to 1 meter or a little longer than that, but they can lift a weight of 400 pounds due to large areas of muscle attachment on their bones. The closest relatives to T-Rex are considered to be the chickens.
After seeing all the facts and studies, we can conclude by saying that T-Rex has got an excellent vision and it can see you even if you stay still.
