What was the function of the small arms of the T. rex dinosaur?

KOMPA.com – Tyrannosaurus rex is considered to be one of the scariest animals to ever inhabit the Earth.

The muscular body of the T. rex extends 12 meters from the snout to the tip of the tail, weighing almost 8 tons.

T. rex most likely preyed on live animals, sometimes eating each other or rummaging through the carcasses of other dinosaurs.

T. rex has a pair of small arms

This dinosaur had small arms, and the function of these tiny limbs is still a matter of debate among scientists.

Reported by National Geographicsome scientists believe that T. rex’s tiny arms are an evolutionary remnant or for non-predatory purposes such as helping it cling to a mate.

Others suggest that T. rex’s arms may have been adapted for a “ferocious cut” at close range, given their ability to inflict deep wounds with their large claws.

Meanwhile, according to Steven Stanley, a paleontologist at the University of Hawaii, the T. rex’s arms are being used to cut their prey.

According to History.com, T. rex small arms have curved crescent-shaped claws that can be used to injure prey.

And the short arm length is actually more useful for cutting, given the size of the T. rex’s head.

In the past, it was believed that T. rex’s arms were nothing more than remains after years of predator evolution, like the wings of flightless birds.

However, several factors led Stanley to conclude that T. rex’s small arms could be useful for the predator’s survival.
