One of the most terrifying creatures ever to exist in Earth's history is tyrannosaurus rex, also known as T-rex.
To describe, the T-rex has a large and aggressive appearance, with the most terrible teeth. Science calls them princes of the dense forests of ancient times.
However, the T-rex has a very unreasonable character, it is small hands, assertive and ridiculous, not worthy of the stature of this animal. With their hands, even science doubts their ability to hunt.
However, according to a recent study, the hands turned out to be effective. According to Steven Stanley, a palaeontologist from the University of Hawaii, even though their hands are small, they can still produce extremely dangerous kicks.
Little hands are the subject of many jokes from netizens.
Stanley thinks that the prejudices surrounding the tiny arms of the poor T-rex are not fair. In his research, he points out that it is a feature of T-rex, which helps them attack enemies in narrow range.
"Despite being short, the arm was very strong, with huge claws suggesting that T-rex, despite being attacked from the rear, could still produce at least 4 meter long rays, at least a few inches deep. -ti. " - Stanley wrote in the report.
"And it can repeat those attacks at high speed."
To prove this hypothesis, Stanley directly drew on the traits that showed strength from T-rex's arm - which included skeletons and muscles with the proper mechanism. In addition, the front of the T-rex has only two nails on each side, which increases the risk of injury. For comparison, common meat-eating dinosaurs have at least 3 claws each.
The foundation is 10cm long, plus the strength from the joints, which will be very long, very deep and very dangerous. It is proof that these little hands are not the evolution of T-rex
Stanley also said that he understood that T-rex's hands had shrunk during evolution, to make room for the massive jaw. But clearly, they are very dangerous when T-rex hunts. It must be a natural selection process.
However, other scientists are somewhat disagreeable.
"I believe the damage it causes is huge, but to get a scratch, T-rex must push his chest up, facing the prey, and that's not good," Thomas Holtz from the University of Maryland countered. 
Perhaps that arm has more utility with younger T-rex. But when it grows, its use is fading, "Holtz said.
"The damage zone of the foundation will be larger for the young T-rex, as they must attack small prey.
