Tutwuri.id – Who would have thought that the most familiar Dinosaur Tyrannosaurus Rex or T-Rex while running the rear tail would swing.
This fact appeared in the journal Science Advances on September 22 with the title Predictive simulations of running gait reveal a critical dynamic role for the tail in bipedal dinosaur locomotion.
In the study, it was found that the T-rex also wagged its tail when running like a dog’s tail when he played or ran.
It is also mentioned that the 7-ton carnivore will appear to swing elegantly when this animal is running.
As is well known, most types of dinosaurs have tails with a long and sturdy size which is currently difficult to find a comparison.
It took about 80 million years in the evolutionary process for the descendants of birds to lose their long tails.
This evolutionary process also changed the shape and proportions of these animals, this proves that the tails of dinosaurs also played an important role in their lives.
The researchers also conducted experiments in the form of 3D computer simulations to guess and study how the working mechanism of the dinosaur’s tail worked.
The results obtained were unexpected, in their findings the researchers believed that the dinosaur’s tail wagged up and down and swayed to the right and left when running.

In another study, researchers have also conducted research in which to find out the function of the dinosaur’s tail, ranging from anti-predatory mechanisms, species communication tools, to the role in maintaining body balance and when swimming.
“Essentially, our findings suggest that dinosaurs like Tyrannosaurus and Velociraptor flicked their tails from side to side when they ran, which helped them stay balanced,” said paleontologist Peter Bishop.
