E103 Introduction to Fossils
Fossils were a mystery for thousands of years; then a few pioneering scientists
realized that they were the remains or traces of once-living organisms.
Well-known bone-type fossils are actually rocks, 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 an introduction to fossil expeditions
and a summary of how fossils contribute to our understanding of the earth and
life on it.
There is an especially helpful section on the relationships between fossils
and geology. It covers the principle of original horizontality, the law of superimposition,
the principle of faunal succession, the geological time scale, index
fossils, relative dating, and absolute dating.
All of this is conveyed through detailed illustrations showing the processes,
excellent photographs of representative specimens, and interesting and informative
captions. This poster is a great aid to museum interpretive programs
and is extremely beneficial in the study of both life and earth sciences..
