Sigillariostrobus is the name assigned to the reproductive organs or cones of sigillaria. Unlike the cones of the lepidodendron tree (lepidostrobus ), which grew individually at the very tips of the branches, the cones of sigillaria grew in clusters and were attached further back on the branches. This specimen was recovered during active surface mining operations.
