Tokyo
Millions of years ago there were giant dinosaurs on Earth. Some of them were vegetarian and non-violent while some were extremely dangerous. Of these, Tyrannosaurus rex was considered the ‘King of Dinosaurs’. They had special nerves in their jaws so that they could recognize different parts of their prey and eat it in different ways. Experts from Fukui Prefectural University of Japan have concluded this.

First study to focus on T. rex
Experts scanned the fossil of the lower jaw of T. rex and reconstructed the nerve pattern. Terrible creatures with snake-like mouths were able to do many things with their mouths, such as building houses, caring for children and communicating with each other. The team said that the internal structure of the jaws has been studied in the past on many reptile fossils. This is the first study to focus on T. rex.

more dangerous than expected
Soichiro Kawabe, the author of the research and dinosaur paleontologist at Fukui Prefectural University in Japan, explains that T. rex was more dangerous than we thought. “Our findings suggest that the nerves in the jaws of Tyrannosaurus rex are more complex than any other dinosaur ever studied,” he said. In fact, it is like modern-day crocodiles and tactile-foraging birds, which have very keen senses.

different from other dinosaurs
According to Kawabe, the T. Rex was extremely sensitive to minor differences in material and speed. This means that they were able to recognize individual parts of their prey and eat them differently depending on the situation. He said the research results completely change our perception of T. rex as a dinosaur because the dinosaur was insensitive around its mouth. They were able to bite everything, including bones, with their mouths.

CT scan study
Dr. Kawabe and his colleagues studied the jaw fossils of T. rex discovered from the Hell Creek Rock Formation in Montana. The scientists created nerve patterns by using computed tomography (CT) scans. Then they compared the 3D structure to other dinosaurs. The scientists found that the neurovascular canals of T. rex are complex branching, especially at the front of the mouth.
