Computer modeling suggests that T. Rex was a slow walker

All walking animals have something in common – their preferred walking speed is largely known as “resonance”. Keeping this in mind, what Dutch scientists have calculated May Default running speed has been Tyrannosaurus Rex.

As an animal moves forward, the mass of the center of its body is likewise rhythmic back and forth. To spend as little energy as possible, most organisms mix their motion with a rhythm, the latter of which is determined by factors such as the distribution of weight in different parts of the body.

This faint synchronization of walking speed with mass-shifting-rhythm is called resonance, and that is why walking at your regular speed is actually easy From running unusually slow. Prof. from Vrije Universiteit Amsterdam. Working with Noack van Soest – Prof from Utrecht University. Along with Anne Shulp – Vrije human movement science student Pasha van Bijlert set out to set the pace at which there will be a resuscitation for T. rex.


To do this, scientists created a 3D computer model based on the skeleton of an adult woman Tyrannosaurus Rex It is currently on display at the Dutch National Museum of Natural History. Not only did they digitally add muscle and limbs to their main body, but they also allowed for its massive muscular tail suspension-pull-like sailing, which was back-and-forth with every step.

Based on the team’s biomechanical analysis, it was estimated that the animals would prefer to walk at a speed of 4.6 km / h (2.9 mph). It is actually close to the preferred walking speed of adult humans, which sits at around 5 km / h (3.1 mph).

Van Bijlert says, “There were already some studies examining the walking speed of dinosaurs, but they mostly looked at the legs and ignored the tail.” They usually found much higher walking speeds. What we calculated is low, but it is similar to other animals. “

A paper on research was recently published in the journal Royal Society Open Science. And in an interesting side note, a 2020 North American study determined that based on its anatomy, T. The Rex was designed more for walking than walking.
