Running Dinosaurs Probably Wagged Their Tails.mp4

Amaze Lab

Scientists now think dinosaurs wagged their tails while running, much like modern animals do. The movement likely helped them stay stable at high speeds.

00:00dinosaurs went extinct millions of years ago but that doesn't mean we can't still learn things

00:08about them even today and well birds are the great descendants of the dinosaurs science

00:12alert reports they moved much differently than the modern-day fliers many dinosaur species used

00:17to have rather long tails like the t-rex but experts were never sure exactly why believing

00:22they may have been for predator defense or communication but now researchers from the

00:26queensland museum built 3d modeled simulations using the information we have available on both

00:30the animals biology and physics and this is how they believe dinosaurs with long tails actually

00:35moved with their appendage moving back and forth essentially wagging as they ran researcher and

00:40paleontologist peter bishop says it was imperative to their locomotion saying it was a means of

00:45controlling angular momentum throughout their date the researchers say that not only did this increase

00:49the speed of the creatures but also decrease the effort exerted finding with their simulation that

00:54without the tail 18% more muscular effort was needed to move at the same pace
