When loose sediments become rock, the footprints within them become fossilized.

What can you tell from a footprint?

Scientists can learn a lot from sites where human footprints have been found, including: Estimates of height, weight, and gait of the humans who made the footprints – which also tells us how many people made the footprints.

How do you identify dinosaur footprints?

It may also be possible to determine whether the dinosaur was running rather than walking, and if so, how fast. Footprints also tell scientists whether or not the dinosaur held its tail upright. A droopy tail would have left a telltale skid mark behind the footprints.
