Researchers from the Netherlands have created a new approach to envision how dinosaurs walked. By modeling a T. rex tail as a suspension bridge, the scientists formed a new idea of the animal's walking speed.
Trix, the tyrannosaur from Natural museum in the Netherlands, probably strolled slower—but with more spring in its step—than assumed. This is a first step towards more realistic dinosaur motion.
Humans and animals have a preferred walking speed. This is, in part, influenced by the amount of energy required: they prefer to walk at the speed at which they use the lowest possible amount of energy. One of the ways to achieve this is using something called resonance.
This works for animals that walk on four feet, and for two-legged animals like humans and ostriches. Pasha van Bijlert, student Human Movement Sciences at the Vrije Universiteit in Amsterdam (VU), applied the idea to an animal that walked differently from anything walking the earth right now: Tyrannosaurus rex. These carnivorous dinosaurs didn't just have two legs, they also had an enormous tail that helped them move around.
