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.
How are fossil footprints made?
Help students to understand that fossil footprints happen when an animal steps into a moist surface, such as the mud or sand along a shoreline. The sediment containing the footprints eventually dries. ... As the sediment becomes compacted and cemented together to form rock, the footprints become fossilized.
How are dinosaur fossils formed?
Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
