![]() Next: Why are there oyster shells in the ‘Chalk Pyramids’ of Kansas? Plus: More fossils, more geology, and more paper craft storytelling. Petrified trees and forests from the Libyan Sahara: remains of fossilised tree trunks from Fezzan (Fazzan), in southern Libya, and their GPS coordinates and. Join Charlie Engelman, his sister Kirby, and his friend Patrick as they explore Petrified Forest National Park in this episode of National Geographic Kids’ Nature Boom Time. There are petrified forests located all around the world - Argentina, Egypt, Namibia, India, New Zealand, Canada, and more - but Arizona’s Petrified Forest National Park has one of the largest concentrations of petrified wood on Earth. Mineral-laden water flowing through the covering material deposits minerals in the plant’s cells as the plant’s lignin and cellulose decay, a stone mold forms in its place. The petrifaction process occurs underground, when wood becomes buried under sediment or volcanic ash and is initially preserved due to a lack of oxygen which inhibits aerobic decomposition. The petrified wood is made up of almost solid quartz and is extremely heavy. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material. The park is nearly 350 square miles (more than 221,000 acres). Norcross-Madagascars Extraction area A Petrified Wood is a fossil in which the organic remains. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the stem tissue. Petrified Wood Forest in Madagascars North-West coast. It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization. Petrified wood (from the Greek root petro meaning “rock” or “stone” literally “wood turned into stone”) is the name given to a special type of fossilized remains of terrestrial vegetation. Made primarily from quartz, these geological wonders are actually fossils, and are often colored by additional minerals during the petrification process: Cobalt can create greens and blues, iron oxides create reds, browns, and yellows, and manganese can create pinks and oranges, just to name a few. ![]() Fallen coniferous trees from 211-218 million years ago can be found scattered across the desert of eastern Arizona in the form of petrified wood.
