Petrified wood has also been discovered in Dholavira in Kutch, Gujarat, dating back to 187–176 million years. [24] Japan – there is a fossilized forest preserved at Sendai City Tomizawa Site Museum; Indonesia – petrified wood covers several areas in Banten and also in some part of Mount Halimun Salak National Park.
The name of the park gives it away: Most of the fossils you'll see at Petrified Forest are of exquisite petrified wood from the Triassic period over 200 million years ago.
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. [2]
Araucarioxylon arizonicum (alternatively Agathoxylon arizonicum) is an extinct species of conifer that is the state fossil of Arizona. [1] The species is known from massive tree trunks that weather out of the Chinle Formation in desert badlands of northern Arizona and adjacent New Mexico, most notably in the 378.51 square kilometres (93,530 acres) Petrified Forest National Park.

Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrifaction or petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Fossil wood may or may not be petrified, in which case it is known as petrified wood or petrified tree. The study of fossil wood is sometimes called palaeoxylology, with a "palaeoxylologist" somebody who studies fossil wood. The fossil wood may be the only part of the plant that has been preserved, with the rest of the plant completely unknown ...
A piece of petrified wood in situ, Highlands Ranch, Colorado. The Denver Basin contains relatively few late Paleocene-age strata–with many dating to older periods–but laser ablation sampling in 2015 compared with a core sample from Castle Pines 2.5 kilometres (1.6 mi) away has been interpreted as indicating this more recent date.
