• When you think of
fossils, what pictures
come to your mind?
Fossils
• They are the remains of dead plants and
animals from a long time ago.
There are four types of fossils!
• Imprint
Mold
Preserved Part
Cast
What are Imprint Fossils?
• Imprint fossils are like your footprints.
• An imprint is made when a plant or animal
leaves a print in the soil. The soil then
hardens. The imprint looks like the plant or
animal.
Examples of Imprint Fossils
What are Molds?
• Molds begin when an animal dies.
• The remains of the dead plants and
animals get buried in the mud, and the
mud hardens.
• After a long time, water dissolves the plant
or animal remains and a hole is left. The
hole looks just like the plant or animal that
died.
Examples of Fossil Molds
What are Casts?
• When a mold is later filled with soil, and
the soil hardens, it becomes a cast.
Examples of Cast Fossils
What are Preserved Parts?
• When plants and animals have hardened
and turned to stone.
• This takes a long time to happen
