Fearsome T-rex was a plodder not a sprinter, researchers say
Usain Bolt Align the starting grid with a Tyrannosaurus rex and is left in the dust of the sprinter, according to a computer-aided search that turns assumptions of sun on his head.
While T-rex’s ability to function has been widely debated among paleontologists for decades, the consensus of previous biomechanical models was that the Cretaceous carnivore could handle speeds up to 45 km / h (45 km / h) .
This is more than half as fast as the fastest man in history.
But because of its size and weight, the predator would have broken its legs if it tried to enter a speed race, revealed the University of Manchester research.
“Muscles must be able to generate enough energy to allow high-speed locomotion, but at the same time, the skeleton must withstand the burdens generated by high speed,” said William Sellers University School Professor of Earth Sciences and environment
“… This is where an error occurs. The skeleton of T. rex is not simply strong enough to run the locomotion,” he told Reuters. The researchers used a technique called multi-body dynamic engineering analysis, coupled with machine learning to produce what they say is the most accurate simulation of gait and biomechanics of daytime T-rex.
They concluded that T-Rex was limited to walking speeds of about 5 meters / second, which is equivalent to 12 km / h (less than half the speed of operation of Usain Bolt 27.8 miles / h).
A study published in the Royal Society of Biological Sciences Journal in 2007 suggested at that time a conservative top speed of 18 mph, but fast enough to chase the best drivers over longer distances.
Sellers have said that their study was forced to re-think how T-Rex trapped their prey.
“It certainly would not have been able to drive the prey animals faster,” Sellers said. “This leaves other hunting options like the ambush, and, of course, this means that (discredited) ideas like” T-Rex’s Treasure “should be reconsidered (Written by Mark Hanrahan in London; )
