Regarding dinosaurs, paleontologists still have many areas of uncertainty—but based on what is currently understood, studying and observing these creatures appears to be fascinating.
Approximately 230 million to 66 million years ago, many species of dinosaurs roamed the Earth, boasting surprisingly long lifespans and remarkably fast running speeds. Here are some interesting facts about dinosaurs.
Usain Bolt could outrun a Tyrannosaurus rex
Computer simulations of a Tyrannosaurus rex's running speed show that its maximum speed was about 29 kilometers per hour. While this is not fast enough to catch a car, it is more than sufficient to chase down most humans.

That is, unless you are an athlete like Usain Bolt, who can run at speeds of up to 44 kilometers per hour, you would likely be caught.
But even Bolt would have to run for his life to escape a Dromiceiomimus, a dinosaur with a top speed of around 60 kilometers per hour.
