THE FOSSIL PETRIFIED WOOD

Petrified wood is a fossil. It forms when plant material is buried by sediment and protected from decay by oxygen and organisms. Then, groundwater rich in dissolved solids flows through the sediment replacing the original plant material with silica, calcite, pyrite or another inorganic material such as opal. The result is a fossil of the original woody material that often exhibits preserved details of the bark, wood and cellular structures.

Some specimens of petrified wood are such accurate preservations that people do not realize they are fossils until they pick them up and are shocked by their weight. These specimens with near perfect preservation are unusual; however, specimens that exhibit clearly recognizable bark and woody structures are very common. A wide variety of names are commonly used for petrified wood. "Fossilized wood" is a general term for wood that has been petrified or preserved by other methods of fossilization. "Opalized wood" is petrified wood that has been replaced by opal, an amorphous form of silica. "Agatized wood" is wood that has been replaced by agate, a form of chalcedony or microcrystalline quartz. "Silicified wood" is wood that has been replace by any form of silica, including opal and agate.
