A fossil is

• a dead organism

• a dead plant or animal that is now extinct

• an organisms that died on a rock

• is the preserved remains or traces of once living organisms

The fossil record

• provides an account of all the organisms that have existed on Earth

  and when they lived on Earth.

• outlines Earth's history from early Precambrian time

• outlines all human species

• was created by Charles Darwin

Index fossils must meet two criteria, they must have existed for a short period of time and ...

• be few in numbers

• lived for a long time

• be widely distributed

• be really old in age

The fossil record helps to show that organisms

• have remained exactly the same over time

• have changed (evolved) over time

• have become extinct over time

• have changed very little over time

How does the fossil record help to support the theory of evolution?

• the fossil record shows that organisms slowly change over time

• The fossil record shows that species evolve very quickly

• The fossil record does not support the theory of evolution

If scientists found this fossil, what could they infer?

• what fish are like today
• that this fish lacked oxygen
• what kind of animal ate this fish
• that water once covered the area

Where can the oldest layer be found?

• The top layer
• The middle layer
• They are all the same age
• The bottom layer

How are fossils created?

• Traces of organisms get turned into stone.
• Dead organisms are quickly buried for millions of years.
• Animals get trapped.
• All of the above

In what kind of rock can fossils be found?

• Sedimentary Rocks
• Igneous Rocks
• Metamorphic Rocks
• Granite

In order for a fossil to form, which of the following events must happen FIRST?

• Slowly, minerals in the water replace the bone.

• Sediment covers the bone.

• An animal dies.
