How old is petrified wood from indonesia

Besides the vast analyses of fossil records and broad-stroke visualizations of what petrified forests and fossils can tell us about evolutionary history, petrified wood from Indonesia can tell even a casual observer many things about the organism it replaced. Just like scientists observe dinosaur fossils to understand how dinosaurs lived, similar information can be derived from petrified wood. Most petrified wood comes from vascular plants, and using microscopes and scanning electron micrographs , scientists have been able to distinguish the different cell types of xylem and phloem that helped distribute water and nutrients to the different parts of the plant.

With this, they could compare the cell structure and tissue arrangement of the petrified wood to modern plants to understand how the ancient plants grew and obtained nutrients. No worries! There is still plenty of things that you can learn from a piece of petrified wood without any magnification. First, a good specimen of petrified wood will still have growth rings present.

These rings can be counted to estimate the number of different seasons the tree lived through, giving a rough estimate of how long the tree lived. Further, measurements of the diameter of the petrified wood can allow you to estimate the overall size of the tree, based on its modern relatives and their height-to-width ratio.

Petrified wood is the name given to wood that has been turned into stone fossilized through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained.

For this to happen the wood needs to be buried in an environment both low in oxygen preventing decomposition and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.

But those between these two extremes benefited from ideal conditions. They became naturally sterilised by the heat which destroyed bacteria normally found in decay.

The silica found in volcanic ash became dissolved in the percolation fluids. It gradually replaced the wood, molecule after molecule, by minerals such as quartz, agate or marble, hence preserving the shape of the trees and even their cells.
