According to current research results, the fastest dinosaur may be Tyrannosaurus rex. Although we cannot directly measure the speed of dinosaurs, scientists can estimate the running speed of dinosaurs through analysis of dinosaur bones, muscles and footprints, as well as simulation and comparison of existing animals.
According to these estimates, the running speed of Tyrannosaurus may exceed 40 kilometers per hour, or even up to 70 kilometers per hour. This speed is equivalent to the world record of the 100-meter race in the modern Olympic sprint event, which is far faster than the running speed of most modern animals.
It should be noted that the speed of dinosaurs is also closely related to factors such as body size, and the speed difference between different types of dinosaurs may be very large. In addition, although some dinosaurs cannot run very fast, they may have other excellent escape and hunting strategies to ensure their own survival and reproduction.
