Which of the following is an example of a body fossil?

• A perfect mold of a dinosaur bone
• A carbon print left by a leaf
• The skull of a mammoth that fell into a tar pit
• A dinosaur footprint

Why are deserts, tar pits, and ice good places to find body fossils?

• Most ancient organisms lived in these environments
• Bacteria and other decomposers cannot thrive in these environments
• Many ancient organisms traveled to these places to die
• The largest ancient organisms lived in these environments

In order to form a fossil, an organism must usually ______ quickly after it dies.

• Go extinct
• Decompose
• Rot
• Be buried

What can you conclude from the fact that so many fossils involve shells, skeletons, and teeth?

• Most organisms on earth have shells, skeletons, or teeth.
