Dating petrified wood
Petrified wood is undoubtedly one of the most abundant fossils in the world.In many parts of the world entire forests can be found fossilized with little sign of decomposition. - After serving nearly 30 years as a doorstop for a nuclear physicist, a hunk of petrified wood from Arizona has finally been recognized as a one-of-a-kind find.

Their existence is somewhat of an enigma as wood decomposes extremely fast in environments where trees typically grow.
This happens because wood is composed of sugar (cellulose), which is the preferred food for microorganisms such as bacteria and fungi.
