Even though it seems like you’d need a Jeep Wrangler to outrun a T. rex,Opens in a new tab the gigantic dinosaurs likely had a top speed of only about 17 mphOpens in a new tab. Newly discovered footprints from the La Rioja province of Spain, however, come from a dinosaur that would require a vehicle to outrun. Or at least the athleticism of the fastest people in the world, such as Usain Bolt.
GizmodoOpens in a new tab reported on the footprints of the speedy dino, which paleontologists outlined in a paper published in Scientific ReportsOpens in a new tab. The paleontologists report that the footprints come from what was likely a carcharodontosaurid or spinosaurid. I.e., a carnivorous, bipedal theropod dinosaur.Opens in a new tab I.e., a meat-eating dinosaur that ran on two legs. This fast dinosaur probably grew up six-and-a-half feet tall and up to 16 feet long.
The paleontologists used computer modeling to predict the top speed of the dinosaur. Using the tracks—which come from the early CretaceousOpens in a new tab, or between 145 and 100 million years ago—the team created 3D models. They then used characteristics like the length of the footprints, the dinosaur’s likely hip height, and its stride length, as inputs for the models.
As for the top speed? The paleontologists peg it at about 27.738 mph. Which is, of course, astonishingly fast. Especially for a dinosaur that may have weighed up to 33,000 pounds. That speed, however—technically—wouldn’t have been fast enough to beat Usain Bolt. The Olympic sprinter’s top speed narrowly beats that, coming in at 27.787 mphOpens in a new tab.
Unfortunately, this quick bipedal dinosaur was likely not the fastest dinosaur from the Cretaceous. Some sourcesOpens in a new tab, for example, say that the velociraptor may have been able to reach top speeds of around 40 mph. This means even the fastest human on Earth wouldn’t have been able to outrun it. Nor a Wrangler below third gear either.
