New beautiful Arizona and Madagascar petrified wood slices have arrived at the Tyrannostorus!

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while still retaining original structures such as tree rings. The colors are caused by different metals in the silica-rich fluids that replace the original wood structures. For example, iron oxides create reds and oranges. The area around Ambilobe in northern Madagascar is extensively mined for very colorful petrified wood that was deposited during the Triassic period, approximately 220 million years ago. Nearly all of this wood is from the Araucaria genus, a type of conifer today referred to as the monkey puzzle tree or pehuén.

The Arizona petrified forest is probably the best known in the world due to its vibrantly colored “rainbow wood” and the Petrified Forest National Park. This petrified forest is part of the Late Triassic-aged Chinle Formation and extends over a huge area—around 100,000 acres—but only a small portion is located within the national park. The fossilized wood is approximately 225 million years old! The dominant tree species in the forest is Araucarioxylon arizonicum, a type of conifer related to the living pehuén, or monkey tree.
