Question: Why are dinosaur footprints preserved?

When dinosaurs walked through the mud they left footprints, just like you do on a muddy trail. Over time these footprints were filled with sand or small pebbles and eventually hardened into rock. The footprints were preserved for millions of years until erosion brought them to the surface where people can see them.

Why are dinosaur footprints raised?

Millions of years ago, dinosaurs left their tracks in sediment. Typically, the soil was wet — part of a shoreline, a mudflat or even the bottom of a shallow sea. As the area dried, the tracks hardened. Eventually, another layer of sediment filled the prints, protecting them from erosion or damage.

What could destroy the footprints?

The vast majority of tracks are not fossilized — they are destroyed shortly after they are made. Tracks can be obliterated by being eroded by water, blown apart by wind, stepped on by animals, or damaged by other forces.
