Introduction to Fossils
This poster begins by explaining what fossils are and how a
few pioneering scientists eventually realized that they were the
remains or traces of once-living organisms. Many people think
fossils are petrified bones but bone-type fossils are actually
rocks. They are the result of a process called mineralization in
which minerals replace decaying tissue. This process is shown
and explained. All of the other fossil types are also explored.
The rarity of fossils is dramatically presented (see below) and
strange things sometimes mistaken for fossils are identified.
There’s a great section on fossil expeditions and one that
discusses what fossils tell us. All of this is accompanied by
detailed illustrations showing the processes and excellent
photographs of representative specimens.
There is an especially helpful section on the relationship
of fossils to geology. It covers the principal of original
horizontality, the law of superimposition, the principle of
faunal succession, geological time charts, index fossils, and
both relative and absolute dating. This poster is a great aid to
museum interpretive programs and extremely beneficial in the
study of both life and earth sciences. |
