More than 66 million years ago, the beast prowled the late Cretaceous forest, hunting for a Triceratops or Edmontosaurus to eat.

The king of the tyrant lizards' main flaw was its small arms. T. rex wasn't the only dinosaur having short arms in comparison to the rest of its body

But why did so many theropods have such short arms? A few theories have been offered by scientists.

According to the journal Acta Paleontologica Polonica, bone-crushing theropods like T. When feeding, rex evolved short arms so they wouldn't bite each other's arms off.

therefore the research author speculated that the small limbs developed to minimize inadvertent arm-ripping when a swarm of theropods swooped on a grappled Triceratops.

"It's a beautiful narrative," said John Hutchinson, a biologist at the Royal Veterinary College at the University of London who was not involved in the study.

Hutchinson is a researcher that focuses on the biomechanics of locomotion in huge terrestrial creatures, both extant and extinct.

"As the creatures grow larger, the forelimbs shrink and the skull expands," he explained.
