Automatic TRANSCRIPT

One has ever seen tarinah source walk. Still movies like jurassic park have guessed how fast it would have done that now. Scientists have used the skeleton of t. Rex to model the bio mechanics of the animals stride and they've estimated its dreaded at a leisurely pace on par with humans. Ostriches elephants and giraffes. And it's not just limited to those animals. Horses gazelles news. Turns out that actually. Most animals don't tend to walk. Superfast pasha von beyeler is a movement. Scientists had variety university in amsterdam. His team studied the skeleton of not. Rex housed in a dutch museum. The specimen nicknamed tricks is exceptionally well preserved. So they were able to. How ligaments would have attached to and linked to the animal's tail bones. Those ligaments they would've acted like rubber bands and the researchers used mathematical modeling to study. How they would have given the tail bounce as the t. rex. The animal could have taken advantage of that natural bouncy rhythm to save energy as it moved that is basically resonance you get more movement for less effort if you choose to correct rhythm at which you do things so that helped estimate the beat which t rex would have pounded its feet but to determine speed. They still needed to know how far each step was and to do that. We found fossilized track way of a slightly smaller through sword. Skilled it up to the size of our t. rex and that gives you a step length. Multiple is step length by step rhythm and you get a speed of one point two eight meters per second or about two point nine miles per hour. The results were published by the royal society. Von bildt says he's seen a lot of headlines stating that humans could have outpaced t rex. Not so he says. Once the animal started running. I guess we should be glad that there's a lot of time between us and t-rex
