Scientists from the University of Manchester constructed a computer model and it showed that this dinosaur couldn’t run, but could only walk fast. Its weight was more than 7 tons and research confirmed that running was bad for its skeleton. All in all, the tyrannosaurus’ maximum speed was only 16 mph. As a result of this research, palentologists are now discussing its feeding behavior because there is a new assumption that the tyrannosaurus may have been a scavenger.
