225 Million Year Old Petrified Redwood

Yes that is not a joke and not an exaggeration. I bought a box of rocks about 25 to 30 years ago. This was one of the specimens inside. when I asked where he got this piece he replied his father took it from the Arizona National Redwood Park in the late sixties.

The Petrified Forest is known for its fossils, especially fallen trees that lived in the Late Triassic Epoch, about 225 million years ago.

While many of the trees rotted away, some were buried by the quick-moving water. When winds carried ash from distant volcanoes, minerals from the ash infiltrated the wood, forming crystals. Crystals occasionally replaced individual cell walls, preserving the petrified wood in detail.
