What is special about a petrified fossil?
Petrified fossils result from permineralization, the replacement of once-living matter by minerals. Solutions containing silicates, carbonates, iron or other minerals seep into the gaps and spaces between the cells, first encasing the cells and eventually replacing the cells themselves.
What is the oldest petrified fossil?
The Gilboa fossil forest, in the Catskill Mountains in upstate New York, has for several years been recognized as the oldest known fossil forest. And yet it has long been hard for investigators to access. Wattieza, the oldest known tree, stood up to 10 m tall and resembled modern tree ferns.
What is petrified fossil?
Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone. This generally occurs by filling the pores of the tissue, and inter and intra cellular spaces with minerals, then dissolving the organic matter and replacing it with minerals.
How can you tell how old a petrified wood is?
How Do They Determine How Old Petrified Wood Is?
- Relative Dating: By determining the age of the sedimentary rocks in which a fossil is buried.
- Biostratigraphy: By dating the age of other known organisms fossilised within the same layer.
- Radiometric Dating: By calculating the percentages of radioactive elements.
How do you identify the petrified fossil?
Some bone parts have more pores (porous), while other parts are denser. The pores in porous bone are obvious and can be seen without using any kind of magnifier. In denser bone, it is harder to see or feel. If you cannot find any pores, then you probably have petrified wood.

Petrified wood forms when fallen trees get washed down a river and buried under layers of mud, ash from volcanoes and other materials. Sealed beneath this muck deprives the rotting wood from oxygen — the necessary ingredient for decay.
How old is petrified bone?
They first appear as fossils in rocks of earliest Cambrian age, and their descendants survive, albeit relatively rarely, in today’s oceans and seas. They were particularly abundant during the Palaeozoic Era (248 to 545 million years ago), and are often the most common fossils in rock of that age.
