Lepidodendron trunk (pos/neg) with branches & nodes (315+ myo), Plainville, MA 9/4/2001
This 315 million year old [mid-Pennsylvanian] Lepidodendron trunk section (pos & neg) cast from Plainville, MA clearly shows bark, branches and nodes. Lepidodendron, a giant club moss, grew up to 100 feet tall. Its stumps sometimes became nests or traps for primitive reptiles and amphibians. For this reason Lepidodendron stigmaria is often a sign that the area is prime for tracks.
