Many [[Young Earth Creationists]] disagree with the idea that fossils could be millions of years old because they believe the Earth to have been created only several thousand years ago. They point to the fact that some dinosaur bones have been found that still contain organic matter as evidence that these creatures were alive only several thousand years ago rather than 65 million years ago.  They also point out that sometimes bones can fossilize very quickly if they are in the right place, so even though scientists predict that the process will usually take a very long time, this is not always the case.<ref>Answers in Genesis: [http://www.answersingenesis.org/creation/v21/i1/dinosaurbones.asp "Dinosaur bones—just how old are they really?"]</ref>

The data recorded in fossils, known as the fossil record, constitute the primary source of information about the history of life on the Earth. Only a small fraction of ancient organisms are preserved as fossils, and usually only organisms that have a solid skeleton or shell. A shell or bone that is buried quickly after deposition may retain organic tissue, though it becomes petrified (converted to a stony substance) over time. Unaltered hard parts, such as the shells of clams, are relatively common in sedimentary rocks. The soft parts of animals or plants are rarely preserved. The embedding of insects in amber and the preservation of mammoths in ice are rare but striking examples of the fossil preservation of soft tissues. Traces of organisms may also occur as tracks, trails, or even borings.
