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
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.
