This is a section of fossilized "petrified" wood that was recovered from the Peace River in Florida's famous Bone Valley formation (Hardee County, Hawthorn Group). The exact species of this specimen is not identified, but it likely dates from the Pliocene or Pleistocene periods (many thousands or millions of years old). Most petrified wood that comes from this region is the white-colored variety. The white variety is silicified and the replacement minerals are silicates. The specimen being offered here is the dark-colored phosphatized variety, which is much more scarce compared to the white. This wood was mineralized in an environment that is rich in phosphate minerals. The phosphates cause the resulting mineralization to take on a dark coloration - usually dark brown or black. The Bone Valley formation of Florida has one of the world's most productive deposits of phosphate and the Peace River produces phosphatized fossils on occasion.
