Dinosaur footprints
How to work out the height and gait of the dinosaurs  
Diagram, Pete Loader 
FL = length of hind foot
SL = stride length of either right or left hind foot Equations:

If the foot length of each
dinosaur is measured and multiplied by 4, the resulting figure gives the hip height.
With this figure, and using the equations provided, it is possible to calculate whether the dinosaur was
walking, trotting or running.
Either dinosaur could be a carnivore or a herbivore so there are endless possibilities for the stories to be made about them.
The layout of the dinosaur trackway and the equations needed to calculate the hip height of the dinosaur and its relative speed.
