This dinosaur had arms that were around one metre long, tiny when compared to the size of its body. How T. rex used its small arms has long puzzled palaeontologists and the public.
rex cast that dominates the atrium outside the doors of the UCMP, is that none of the hypotheses would actually work. “The arms are simply too short,” he said. “They can’t touch each other, they can’t reach the mouth, and their mobility is so limited that they can’t stretch very far, either forward or upward.
It’s also been said that the T-Rex’s short arms may have actually been wings – as if there haven’t been enough memes about their little arms. So, the feather theory states that the arms of the T-Rex might actually have been inverted, like that of an ostrich.
The most likely explanation for T. Rex’s oddly proportioned arms is that they were exactly as big as they needed to be. This fearsome dinosaur would quickly have gone extinct if it didn’t have any arms at all — either because it wouldn’t be able to mate and produce baby T.
Stranger still, the puny arms are nonetheless quite powerful: Analyses have shown a T. rex’s arm could bench press 400 pounds. And yet, despite this raw strength, the arms were not only short, but possessed a limited range of movement, as well, only capable of swinging across at an angle of about 45 degrees.
