How Fast Could Dinosaurs Walk Or Run?

It is very hard to say how fast the dinosaur could walk or run because no one really knows. However, scientists have estimated that dinosaur speeds would have varied because there are several different methods that are used to calculate them. One recent estimate suggests that an average person might have been able to outrun an adult Tyrannosaurus  - although you probably would not advise someone to try. The two basic approaches for estimating dinosaur speed are comparing to recorded speeds of modern animals of similar body size and build, and measuring distances between fossil footprints in a trackway and using these distances to calculate estimated speed. Walking-speed estimates for medium-sized bipedal (two-legged) dinosaurs vary from 4 kph to 6 kph, and peak running-speed estimates vary from 37 kph to 88 kph. The highest figure (88.6 kph) is the same as the peak speed of the currently fastest land animals, such as the North American pronghorn and very probably is too high.
