Real fossils are covered by sediments (mud or sand) and take thousands or millions of years to form. Some
fossils are formed when an animal makes an imprint in the sediment and then other sediments settle into
that impression to preserve it. The same thing happens in this activity when the plaster fills and preserves
the impression of the dinosaur.
