Did You Know?
A remnant, impression, or trace of an animal or plant of a past geologic age that has been preserved in the earth’s crust is called a fossil. Data from fossils are 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. Unaltered hard parts, such as the shells of clams, are relatively common in sedimentary rocks. 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 such as tracks and trails may also be preserved.
