T rex dinosaur could not have run at high speed: Study

London: The size and weight of the giant T rex dinosaur would have made the fearsome carnivore unable to run at very high speeds, according to a new study which proves that a classic chase scene from the Jurassic Park movie was scientifically inaccurate.

In Stephen Spielberg's original adaptation of the Jurassic Park, a rampant Tyrannosaurus rex (T rex) is shown chasing Jeff Goldblum's character, Ian Malcolm, as he sits injured in the back of a 4x4 vehicle.

"However, different studies using differing methodologies have produced a very wide range of top speed estimates and we say there is a need to develop techniques that can improve these predictions," Sellers said.
"Here we present a new approach that combines two separate biomechanical techniques to demonstrate that true running gaits would probably lead to unacceptably high skeletal loads in T rex," he said.
The results also mean that the T rex could not pursue its prey in a high-speed chase as previously thought.
"Being limited to walking speeds contradicts arguments of high-speed pursuit predation for the largest bipedal dinosaurs like T rex and demonstrates the power of Multiphysics approaches for locomotor reconstructions of extinct animals," he added.
Although the research focuses on the T rex, the findings also means running at high speeds were probably highly unlikely for other large two-legged dinosaurs such as, Giganotosaurus, Mapusaurus, and Acrocanthosaurus.
"Tyrannosaurus rex is one of the largest bipedal animals to have ever evolved and walked the earth," Sellers said.
"So it represents a useful model for understanding the biomechanics of other similar animals. Therefore, these finding may well translate to other long-limbed giants so but this idea should be tested alongside experimental validation work on other bipedal species," he said.
