Many people are familiar with fossilised wood as a decorative item from the museum shop. Together, these sites constitute one of the most extensive occurrences of fossilised wood in the Northern Hemisphere. If the subsequent uplift to the Earth’s surface is taken into account, this period extends to as much as 300 million years. As fossilised wood occurs in many rock formations worldwide, this opens up a valuable source of information.
