 Tyrannosaurus Was Not A Fast Runner   (Site not responding. Last check: )
Some believe that Tyrannosaurus could not run, or at best was limited to a top speed of 11 m/s (40 km/hr, 25 miles/hr), while others argue for speeds of 20 m/s (72 km/hr, 45 miles/hr) or more.
If we are correct that Tyrannosaurus was not a fast runner, that does not mean that it was cold-blooded or sluggish, nor does it mean that it was warm-blooded or agile.
The argument that if Tyrannosaurus could not run quickly, it could not have been a predator because it could not have caught potential prey, is nonsensical because the aforementioned potential prey were likely just as inept at running as Tyrannosaurus was.
