• MASSIVE TRIASSIC ARIZONA
  MASSIVE TRIASSIC ARIZONA PETRIFIED WOOD SLABNorth America, Southwestern United States, Arizona, Late Triassic, ca. 225 million years ago. This is one of the largest fossilized or petrified wood slabs we have - a natural disc that is cut from a prehistoric tree trunk's cross section and highly polished on both planar faces. Fossilized tree cross sections, also known as "tree cookies," are not only beautiful but provide invaluable information about the prehistoric climate and landscape. The exterior bark is fossilized, replaced by rough stone, while the smooth interior features incredible russet orange, maroon, deep gray-blue, and creamy white hues from the quartz and agate that formed over millions of years. The polished surface is pleasantly tactile, and just like natural wood today the graining and coloration of each petrified slab is unique with special character. Again, this is a truly massive piece from a tree that must have been hundreds of years old before it even fossilized! Size: 27.5" Diameter x 1.25" W (69.8 cm x 3.2 cm) Fossilized trees from this time period come from the Chinle Formation of the southwestern USA, and the beautiful colors found in the formation - exemplified this fossilized tree slab - give the Painted Desert of Arizona its name. Due to plate tectonics, this area was near the equator on the supercontinent Pangaea during the Late Triassic, which gave it a humid, sub-tropical climate. It was a floodplain below mountains to its south and a sea to its west; as a result, massive trees washed down from the mountains and came to rest in sediments that preserved them and fossilized them. The petrification process involves the rapid burial of the tree or pieces under sediment which prevents the usual decay. Flooding and volcanic activity are usually responsible for creating the layers of sand, silt, and ash needed to create the right types and amount of sediment. Mineralized water can then permeate through the wood, coating cell walls and filling the intercellular cavities which then fossilizes into stone. The detailed preservation of the wood, including knots, rings, and bark, are possible because the organic wood molecules become coated and surrounded with smaller silica molecules. Nine different species of tree have been discovered in the fossilized deposits in the region; usually identified as Araucarioxylon arizonicum, an extinct conifer tree (and the state fossil of Arizona). Fascinatingly, the Ancestral Puebloan people who lived in the region approximately 1000 years ago used petrified wood for making tools and even building houses! Provenance: private Berthoud, Colorado, USA collection All items legal to buy/sell under U.S. Statute covering cultural patrimony Code 2600, CHAPTER 14, and are guaranteed to be as described or your money back. A Certificate of Authenticity will accompany all winning bids.

• VIBRANT ARIZONA TRIASSIC
  VIBRANT ARIZONA TRIASSIC PETRIFIED WOOD POLISHED SLABNorth America, Southwestern United States, Arizona, Late Triassic, ca. 225 million years ago. A massive and gorgeous slab of fossilized, petrified tree trunk, sliced crossways and highly polished on both planar sides to showcase the broad interior rings of the tree - not only beautiful but providing invaluable information about fossilization processes! The exterior bark has also fossilized, replaced by rough stone, while the smooth interior features incredible, colorful quartz, agate, and translucent crystalline structures which are visible in the small vugs (cavities)! It is quite possible these vugs were caused by insect activity before fossilization. The colors are mesmerizing - dominated by warm hues of red and maroon, purple, with creamy white and lilac blue striations and swirls. The photos are nice, but the subtle shimmering crystal are best appreciated in person! This is a stunning piece to display or to use as a side table with the addition of a sturdy base! Size: 15.5" Diameter x 1" W (39.4 cm x 2.5 cm) Fossilized trees from this time period come from the Chinle Formation of the southwestern USA, and the beautiful colors found in this formation - exemplified by the colors of this fossilized tree - give the Painted Desert of Arizona its name.
