in tree sap which hardens and traps them forever. Large
animals can get trapped in ice, or their carcass gets
trapped.
in layers of rock. Over thousand of years, pressure
builds up
and the ground. Next  the mould left if filled with minerals
that form rock. This rock is shape is the fossils - an exact
replica of the dinosaurs. This process takes 10,000 years.
Palaeontologists find fossils when the top layer of dirt or rock
washes away.
