In a new study published in Acta Palaeontologia PolonicaKevin Padian, a professor of integrated biology and curator at the University of California Museum of Paleontology, believes the T-Rex’s arms have evolved to be short to reduce the chance of accidental shredding during brake feeding. While tyrannosaurs are often thought to have hunted alone, more recent evidence suggests that many of them may have actually hunted in herds. That being said, when it came time to feed, the animal’s huge jaws and sharp teeth could cause quite serious damage to anything caught in its path. Padian suggests in his report that “during mass carcass feeding, limb reduction was chosen to keep the front limbs away from the jaws of large, similar predators, avoiding injury, blood loss, mutilation, infection and death.” Speaking to Berkeley News, Padian elaborated on his hypothesis, saying: “What if many adult tyrannosaurus converged on a trunk? You have a pile of bulky skulls, with incredibly strong jaws and teeth that tear and cut flesh and bones right next to you. What if your boyfriend there thinks he’s too close? They may warn you by cutting off your hand. “So it could be an advantage to cut the front limbs, since you do not use them in hunting anyway.” For many years, it was speculated that the T-Rex’s tiny arms were merely an evolutionary background, such as a human wisdom teeth or the wings of some non-flying birds. Over the years, however, some paleontologists have begun to believe that the short front edges of the T-Rex could also have evolved to help them flip over other large dinosaurs, hold a mate in place, or pierce prey. in close distance. While he does not assume that his new case is the ultimate reason for anything, Padian is also not convinced that any previous proposals are viable, saying they are “untested or impossible because they can not work”. LEGO Breakout Jurassic Park T-Rex set “And none of the hypotheses explain why the arms will get smaller,” he said. “The best they could do is explain why they would keep the small size. And in any case, all the proposed functions would have been much more effective if the arms had not been reduced “. Padian expects that he can greatly strengthen his theory by studying fossilized bite marks on existing specimens in museums around the world. It’s not the only T-Rex theory we’ve just heard – some scientists now claim that the T-Rex was actually three different species. As for the rest of us, we will probably do most of our T-Rex research by watching the Jurassic World Dominion later this year. Billy Givens is a freelance writer at IGN.
