New discoveries show that the terrifying Tyrannosaurus rex is big and strong, but slower than running humans.
All children know: Tyrannosaurus is probably the most famous dinosaur, especially in movies. But what exactly is this terrible lizard like?This is an object The Royal Society publishes new research.
Tyrannosaurus rex is 13 meters long and weighs about 9 tons. In comparison, an African elephant weighs about six tons. Tyrannosaurus is not a casual person, so it has a reputation as a terrible hunter.
In the movie “Jurassic Park”, Tyrannosaurus rex chases after the protagonists who barely escape by driving. However, some studies have found that this dinosaur is clearly calm when moving.
According to anatomical analysis by a group of Dutch researchers, the normal walking speed of Tyrannosaurus Rex is about 1.28 meters per second, which is equivalent to 4.6 kilometers per hour, which is slower than its walking speed between humans by 4.8 and 5.1 kilometers per hour.
How do you calculate the speed of Tyrannosaurus Rex?
The novelty of the study is that researchers at the University of Amsterdam have used a method called natural frequency for estimation.
The normal gait speed of an animal can be determined by the natural frequency of the body part involved. Although the tail of a bipedal dinosaur (such as Tyrannosaurus rex) was actively involved in gait activities, it was passively suspended by the interspinous ligament.
These ligaments in the tail are like a spring, which can store elastic energy, thereby reducing the energy required for movement. In order for elastic energy storage to be effective, the pass frequency and natural frequency must match.

Dutch researchers used 3D reconstructions and biomechanical models of Tyrannosaurus vertebrae and joints to estimate the natural frequency of tail oscillations. Their hip height is 3.1 meters and their stride length is 1.94 meters.
The author writes that the determined walking speed of 1.28 meters per second is actually lower than the estimated speed of previous studies. However, this is not the fastest way to walk, but the preferred way of walking for Tyrannosaurus rex.
Previous research has shown Tyrannosaurus did not even reach 30 kilometers per hour Runtime. In comparison, former sprinter Usain Bolt averaged 38 kilometers per hour within 100 meters.
