T. rex quicker than Becks, say scientists
Date:8/21/2007

speed of just under the 8 metres per second of T. rex.

Musculoskeletal details of a 30kg South American emu and a 65kg ostrich were fed into the program next and top running speeds of 13m/s (about 30mph) and 15m/s (35mph) were calculated respectively.

The process was then repeated using the musculoskeletal data of five bipedal meat-eating dinosaurs a 3kg Compsognathus, a 20kg Velociraptor, a 430kg Dilophosaurus, a 1.4 tonne Allosaurus and the 6 tonne Tyrannosaurus.

The figures we have produced are the best estimate to date as to how fast these prehistoric animals could run, said collaborator Dr Manning, a lecturer in palaeontology in the School of Earth, Atmospheric and Environmental Sciences.

Since the movie Jurassic Park, scientists have questioned the speed of these dinosaurs and some have wondered whether Tyrannosaurus could have run at all.

Our research, which used the minimum leg-muscle mass T. rex required for movement, suggests that while not incredibly fast, this carnivore was certainly capable of running and would have little difficulty in chasing down footballer David Beckham for instance.
