Anotations

Scope note:

Remains, impressions, or traces of humans, animals, or plants of past geological ages that have been preserved in the earth's crust. The complex of data recorded in fossils worldwide--known as the fossil record--is the primary source of information about the history of life on Earth. Only a small fraction of ancient organisms are preserved as fossils, and usually only organisms that have a solid and resistant skeleton are readily preserved.
