Paleontology is the study of pre-existing life based on fossils. A fossil could be an actual portion of the animal, such as bones, teeth, or shells, or maybe replaced by minerals such as silica, iron and manganese as in petrified wood. A fossil may also be a track or a trail, an imprint or a cast, anything that indicates preexisting life forms. Through paleontology, scientists hope to create a more complete understanding of how life has changed since it first appeared in the geologic record of time.
