__Fossils__ are the remains or traces of life throughout the earths history. __Fossils__ can be anything from mineralized teeth, wood, fur, rocks, plants, bones, and so on. Though __trace fossils__ are clues that indicate the activity of an organism; like eggs, nest, footprints, shell or leaf impressions, coprolite and so on. __Coprolite__ is one of the most useful trace fossils that is of an organisms feces.

Fossils are preserved in the layers of the earth that are compressed together after many years. Though these layers may not be as accurate, because over time there have been many obsticle that can happen to affect the layers; like earthquakes, faults, and maybe even eroided. These fossils and layers are stored on a record known as the, or the. The fossil records holds imformation about the living organisms that have lived in these times and about the types of environment these organisms have lived in. This table can date from present day to about 4500 mya. It also has a time scale or Eon that can be sub-divided into Era, then to Period, and then into Epoch.In the geologic time scale there are:
 * __Hadean Eon__ (4500-3800 mya)
 * __Archean Eon__ (3800-2500 mya)
 * __Proteroic Eon__ (2500-543 mya)
 * __Phanerozoic Eon__ (543 mya - present)
 * __Paleozoic Era__ (543-248 mya)
 * __Mesozoic Era__ (248-65 mya)
 * __Cenozoic Era__ (65 mya-Present)
