On Line Calculator for Estimating Dinosaur Speed and Gait
Dinosaur footprint diagram  The key to deriving estimates of
dinosaur gait and speed from trackways was provided by the
zoologist R. McNeill Alexander (1976). From observations of
modern animals he derived a general relationship between an
animal's speed of locomotion (v) and its hip height (h) and its
stride length (SL), which is  v = 0.25*g0.5*SL1.67*h-1.17
Alexander also pointed out that this formula could be applied to
dinosaur trackways since the stride length can be measured
directly and the hip height could be estimated from the size of
the foot print.  The stride length is the distance between
successive prints of the same foot.  Alexander estimated from a
range of dinosaur skeletons that the hip h
