A diagram of a crushed ammonite fossil is shown.

The organism represented in this fossil...

• fed mostly on fish and algae.

• moved by using many tiny legs.

• lived in an environment that required a hard shell for protection.

• had an internal skeleton that was used to maintain the organism's shape.

What must happen to an organism's body for it to become a fossil?

• It must remain above ground.

• It must dry out in the sunlight.

• It must be buried right after death.

• It must be eaten by other animals.

Where are most fossils formed?

• near volcanoes, because the high heat of the lava helps to form fossils

• in glaciers, because fossils are created when an organism is frozen quickly

• in sedimentary rock, because being buried in sediment helps to form fossils

• near earthquakes, because the shaking ground traps organisms to create fossils

Which type of scientist studies life that existed long ago, mostly by studying fossils?

• biologist

• zoologist

• botanist

• paleontologist
