@ImAnotherZang They used to think he could run 40 mph, but nowadays we don't think so. Why? If T-Rex wanted to run that fast, he would need at least 80% of his muscle mass in his legs, which is physically impossible.

@TiG3Rooo heard its something between 20-30 mph, calculated from calculating the muscle-needed-for-speed from ostrich (since both birds and dinos are archosurs, theyre closely related) and then matching the info to the muscle-tissue-mark shown on t-rex leg bones.
