Can the tyrant dinosaur run?

According to the calculation, the experts from Stanford University (USA), tyrant dinosaurs (Tyrannosaurus rex) will not Tyrannosaurus rex - Tyrannosaurus rex (Photo: fossilmuseum.net) can not run as fast as the characters of Jurassic Park movie , even they do not even know . run!

According to them, if they want to run, about 80% of their body weight needs to be put on the hind legs and this is an impossible thing to take place.

Previously, some archaeologists had compared the long, slender legs of dinosaurs to today's animals like ostriches or horses and concluded that dinosaurs could run up to 72 km / hr. However, two professors John Hutchinson and Mariano Garcia of Stanford University proved that in order to run, it is imperative that both animals' legs must leave the ground.

So a tyrant dinosaur weighs an average of 6 tons or more and wants ' reels ' at a speed of 72km / hour, its leg muscles must account for 80% of the body weight. But this is absurd, because in the vertebrates that humans have known today (including dinosaurs), the muscle to weight ratio is only about 50%. This finding also helps explain why so far people have not found fossils of the complete runaway dinosaurs.
