Paleontologists Find Why T-Rex has Short Arms

Paleontologists’ proposed explanations for mating, holding, or stabbing prey, toppling over a Triceratops. But the pupils, who were frequently looking a lifesize copy in the face, were skeptical. “No one knows,” Padian would usually respond. However, he thought those who suggested a solution to the problem approached it from the incorrect angle.

Padian believes that rather than asking what the T. rex’s small Arms developed to perform, the question should be asked what utility those provided to the entire animal. The paper was published in the journal Acta Palaeontologia Polonica. The researcher said that the most ferocious predator’s shrank in length to prevent major accidents or any kind of amputations. When a group of ferocious predators landed on a corpse with their big heads and strong teeth.

Padian pointed out that tyrannosaurids’ forefathers had longer Arms, thus there had to be a reason for their shrinkage in size and joint mobility. He believes that this would have harmed not only T. rex, which lived in North America at the end of the Cretaceous period, but also African and South American abelisaurids from the mid-Cretaceous and carcharodontosaurids, which roamed Europe and Asia in the Early and Mid-Cretaceous periods and were even larger than the ferocious predator.

The great dinosaur hunter discovered the predator fossils in 1990 and they thought to themselves that the Arms were too small. His teammates also described various reasons for the to be small. The Arms might have been pectoral claspers limbs that hold the female in place during copulation.
