Petrified Logs - Giant Logs Trail
These petrified logs are located along the Giant Logs Trail behind the Rainbow Forest Museum. The common fossil trees include Araucarioxylon, Woodworthia, and Schielderia,along with other plants including cycads and ferns. These trees grew on an ancient coastal floodplain and were preserved after washing into rivers and buried by mud during floods. Although many places in the world have analogous environmental settings, modern studies suggest that none of these ancient plants have modern equivalents. The fossils preserve a record of life in the Late Triassic Period, about 225 million years ago.
