Answer 3

I. What is a fossil?

Fossils are the remains or traces of ancient life which have been preserved by natural causes in the Earth's crust. Fossils include both the remains of organisms (such as bones or shells), and the traces of organisms (such as tracks, trails, and burrows—called trace fossils).

Paleontology is the science that studies fossils.

II. How do fossils form?

Most organisms that lived in the past left no record of their existence. Fossil preservation is a rare occurrence. To become preserved as a fossil, an organism must:

Have preservable parts. Hard parts (bones, shells, teeth, wood) have a much better chance of being preserved than do soft parts (muscle, skin, internal organs).

Be buried by sediment. Burial protects the organism from decay.

Escape physical, chemical, and biological destruction after burial. The remains of organisms could be destroyed by burrowing (bioturbation), dissolution, metamorphism, or erosion.

Organisms do not all have an equal chance of being preserved. The organism must live in a suitable environment. In general, marine and transitional (shoreline) environments are more favorable for fossil preservation than are continental environments, because the rate of sediment deposition tends to be higher.

One would be the way your text book has fossilized from non-use!
