T Rex ran at 18mph!

The mystery of just how fast the king of the dinosaurs could run might have been solved by a science team from the north of England. The Manchester University team worked out that Tyrannosaurus Rex probably had a top speed of around 18mph — making it faster than many sports stars. T Rex might have been the fiercest dino, but it wasn’t the fastest. T Rex’s speed has fascinated scientists for many years, with some believing that the creature’s huge leg muscles would have prevented it from running too fast.
