6 exceptional and awesome fossils, showing Neuropteris 4x, Macroneuropteris leaf and Sphenophyllum within lovely natural colours, due to mineral gümbelite covering the fossils during a natural heating volcanic process underneath the fossilized layers that resulted in a chemical process within the fossil.
3 different species.
The fossils are between 308 and 305 million years old.
