(EXAMPLE)Casts of flora and fauna are created by (for example) a leaf falling into mud millions of years ago. the mud eventually hardens forming sandstone and therefore, the leaf is embedded within this. bones, twigs, small animals like mice or fish are commonly found in this way. After pressure from surface material or the build up of further sand or mud, whole bodies can become trapped, leaving complete skeleton fossils. Ice is another good producer of foosils or petrified casts, like mammoths, Sabre tooth tigers etc.
Petrified wood is a fossil of a once living tree; the fallen tree is first tree is covered with sediments , then the organic material is replaced gradually by minerals (usually silicate minerals), retaining its shape and form.
Petrified wood often looks like normal wood and displays annular ring patterns, bark, vessels etc. Petrified wood normally lacks the same definition that live (or recently dead) wood does. One obvious difference is that petrified wood is considerably more dense than wood.
Fossils!!
A phylum is used to categorize living things. In the case of petrified wood, it was once living, but the term "petrified wood" can be applied to a number of different plant phyla that have undergone the petrification process over time. The actual type of plant (or tree) would have to be identified in each case, and then the investigator would have to do some research into the fossil record to find the classification of that particularplant.
Wood is biotic because trees are living so is wood -lexie bryson three ocks middle school
Ironwood is the most dense wood in existance. Petrified wood is considered rock. Ironwood is so dense, it will not float on water. See the related link for more information.
xylary fibres are the fibres that form the wood that is the skeleton of the tree.
Petrified Wood

The streak of petrified wood is black or brown. The streak can also be white.

Petrified wood has turned to stone, a type of fossil, It is unlikley that you would be able to burn it.
Petrified wood is the state stone of Mississippi. This was designated in 1976. Mississippi contains a large petrified forest park and museum.
