Petrified wood, also known as petrified tree, is the name given to a special type of fossilized wood, the fossilized remains of terrestrial vegetation. Petrifaction is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement. The organic materials making up cell walls have been replicated with minerals. In some instances, the original structure of the stem tissue may be partially retained. Unlike other plant fossils, which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material.

Akal Wood Fossil Park is a National Geological Monument of India located in Jaisalmer district, Rajasthan. It is also a Biodiversity Heritage Site.
Amkhoi Fossil Park is a fossil park located near Illambazar in the Birbhum District of West Bengal, India. It contains fossilized wood 15 to 20 million years of age and is officially recognized by the State Forest Department of West Bengal. In 2016 while digging a pond the villagers of Amkhoi village, near Ilambazar, found some large bone-like structures. Later it was established that the bone-like structures were actually wood fossils. Fossilized or petrified wood is often considered as semi-precious ‘stones’ and often used in jewellery — fetching a good market value. As the word spread it attracted fossil hunters from far and wide. To prevent the vandalism and theft of fossils the forest department decided to convert the area into a fossil park. In 2017 - 18 the park came into existence and was called Amkhoi Wood Fossil Park. The aim of the park was to create awareness about fossils among students and common people, and also try to help scholars in their research. It is the only fossil park of West Bengal state and has an area of 10 hectares. The fossils are laid out in a manicured lawn surrounded by pathways separated by hedge walls. Bilingual boards narrate the details of not only the fossils, but also about the process of fossilization.
