- Lot Description
North 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!
