Physical properties

Formation & geological history

Formed during the Carboniferous period (approximately 359 to 299 million years ago) when giant clubmoss trees grew in vast tropical swamp forests and became buried in sediment, replacing organic material with minerals over millions of years.

Uses & applications

Used for educational purposes, paleontology research, museum displays, and as a collectible specimen for fossil enthusiasts.

Geological facts

Lepidodendron trees could grow up to 50 meters (160 feet) tall with trunks over 1 meter in diameter. The distinctive scars seen on this specimen are the points where leaves were attached to the bark.

Field identification & locations

Can be identified by the geometric pattern of leaf scars on the surface, commonly found in coal-bearing sedimentary rock strata worldwide, especially in North America and Europe.
