All movies and even earlier research have made us believe that Tyrannosaurus rex was a dinosaur that could move very fast even run.
Now we have to ask: Could T. rex really move that fast? It seems that T. rex could have even difficulties with walking.
Scientists at the University of Manchester say the sheer size and weight of T. rex means it couldn’t move at high speed, because its leg-bones would have buckled under its own weight load.
Their new research contradicts the running speeds predicted by previous biomechanical models which can suggest anything up to 45mph.
According to Professor William Sellers from the School of Earth and Environmental Sciences, who led the team in this research, says that
The results of the study suggest that the T. rex couldn’t pursue its prey in a high-speed chase as previously thought.
This new scientific approach “combines two separate biomechanical techniques to demonstrate that true running gaits would probably lead to unacceptably high skeletal loads in T. rex.
The findings also mean that running at high speeds were probably highly unlikely for other large two-legged dinosaurs such as, Giganotosaurus, Mapusaurus, and Acrocanthosaurus.
