12 m long, 4 meters high, 5 tons. Tthey were the enviable measurements of the female Tyrasonnaurus king. For its 64th episode, Sixième Science, the podcast of Sciences and the Future and 20 Minutes invites you to learn more about this exceptional animal by diving into the many ongoing international studies devoted to this extinct species discovered in 1905.
In the privacy of T. rex
At the microphone, no resuscitated or cloned dinosaurs but two journalists, Joël Ignasse, journalist specializing in paleontology at Sciences and the Future and Romain Gouloumès from 20 Minutes. Both comment here for example on a British study published in April 2021 in the journal Royal Society Open Science which specified that ultimately their speed of movement was not that astronomical. Indeed, much too heavy and bulky, T. rex could not move easily and had to opt for hunting on the lookout in order to be able to trap potential prey in their powerful jaws.
Did you also know what was the crushing power of the latter? Very precisely 30 tons per cm2 as calculated by American scientists. Other clues show that their existence was not as lonely as one might have thought and that they lived – and no doubt hunted – in small packs since bones of several species were found in the same places.
