About Amarillo Petrified Wood
Araucaria is a genus of evergreen coniferous trees found primarily in the southern hemisphere today. During the late Jurassic and early Triassic periods Araucaria had a global presence.
This Araucaria petrified wood is found in the Dockum formation near Amarillo, Texas, and ages to the upper Triassic period. The characteristics that make Amarillo Petrified Wood a desirable collectible, are vivid colors, cellular detail in some samples, and the fact that they are 3D fossils that connect us to a time long past.
Araucaria Amarillo Petrified Wood is formed through a process called permineralization.
- Burial: A tree, in this case an Araucaria, dies and falls to the ground. Over time, it becomes buried under layers of sediment, such as mud, sand, or volcanic ash.
- Mineral-Rich Water: Groundwater, which contains dissolved minerals like silica, flows through the buried wood.
- Mineral Deposition: As the water moves through the wood, the minerals begin to fill in the empty spaces within the plant cells.
- Petrification: Over millions of years, the original organic material of the wood is gradually replaced by minerals.
The specific minerals involved and the conditions of burial can influence the color and appearance of the petrified wood.
