Physical properties

Formation & geological history

Formed when a plant was buried in quiet water or fine sediment, leaving a carbonized compression and/or impression that lithified over millions of years; age cannot be determined visually, but such fossils range from Paleozoic to Cenozoic.

Uses & applications

Primarily a decorative, educational, and collector specimen; not generally used in construction or jewelry. Value depends on authenticity, preservation, size, locality, and documentation.

Geological facts

The dark outline represents concentrated organic carbon and mineral staining after decay and burial. Fine-grained sediments preserve delicate leaves and stems especially well.

Field identification & locations

Identify by a natural branching morphology embedded in layered sedimentary rock, unlike a modern engraving or cast. Common sources include China, Morocco, the United States, and European fossil-bearing basins; avoid cleaning or polishing the fossil surface.
