Petrified forest

Polished slice of a petrified tree from Arizona. When the image is enlarged, the exposed passages and caves of living things that lived inside this tree trunk during the Late Triassic around 230 million years ago become visible .

Petrified Forest near Borth, Wales

A petrified forest is a fossil forest , the components of which have been rebuilt through the process of silicification (incorporation of silicic acids ) and have thus been preserved. Individual parts of fossil wood are called dendrolite or petrified wood or petrified tree .

Corresponding objects often show such a clear structure that one can recognize the plant species with the help of a microscope. Conifers and ferns are very common among them.
