This great carboniferous fossil matrix shows a lovely Pecopteris acuta leaf! There is a crack but I trunked the fossil in lithium waterglass, the matrix is solid as a rock now. The stone was found by myself in October 2026 in the region of the district Saarland in Germany. Found in rest material that came out of a former coal mines in this region. The fossil is between 309 and 302 million years old.
