Inscription. The Dinosaur Valley track impressions were made on broad, shallow tidal flats consisting of sticky, limey mud. Through the action of tides, the imprints slowly filled with clay and silt particles. The filler sediments were a different river-borne material brought down from upland areas.

The track layer became a hard limestone. The filler layer became either a soft shale or a brittle rock called lime marl. Over time, erosion removed the softer filler layer exposing molds of the animals' feet.

Step 2: The imprint fills with sediment of contrasting texture that does not distort the original. Both layers then harden.
Step 3: Differential erosion removes the softer rock type.
