Africa-Press – Liberia. <\/strong><\/span>The author of the new hypothesis noted that his and other hypotheses related to the size of the T-rex\u2019s arms may be hard to substantiate, as the dinosaur went extinct millions of years ago.<\/p>\n

Kevin Padian, a paleontologist and Professor of Integrative Biology at the University of California, Berkeley, has proposed a new hypothesis that might explain why the arms of the dinosaur known as Tyrannosaurus rex are so short.<\/p>\n

In a paper published in the Acta Palaeontologia Polonica journal, Padian postulates that T-rex\u2019s arms decreased in length in order to prevent amputation \u2013 accidental or intentional \u2013 that might\u2019ve otherwise occurred when a pack of these creatures set upon a carcass to feast.<\/p>\n

Thus, he suggested, \u201cit could be a benefit to reduce the forelimbs, since you’re not using them in predation anyway”, noting that bite wounds could result in infection, haemorrhaging, shock, and eventual death.<\/p>\n

Padian noted that the predecessors of tyrannosaurids had longer arms, and that there must be a reason for these limbs\u2019 decrease in size and joint mobility.<\/p>\n

He also observed, however, that any hypothesis regarding this development, including his hypothesis, will be hard to substantiate in light of the T-rex\u2019s extinction millions of years ago.<\/p>\n
