Re: dinosaur speeds

["Ralph W. Miller III" <gbabcock@best.com>]

There are certainly dinosaur trackways that indicate a speed well above human
walking speed (and above human sprinting speed, for that matter).  Look into
Gregory S. Paul's out of print _Predatory Dinosaurs of the World_.  You will see
figures of a couple of theropod trackways which were interpreted to be very fast
-- about 25 mph for the Glen Rose _Acrocanthosaurus_-like track and perhaps 40
mph for a small Arizona theropod!  Paul doesn't provide the formulas or the
math, but you can take it from there.  Check out the chapters "A quick look at
predatory dinosaur footprints" and "Predatory dinosaur speed."
