Physical properties

Hardness: 6-7 (matrix); Color: Grey, tan, and olive matrix with dark carbonaceous residue; Luster: Dull/Earthy; Structure: Clastic with planar bedding

Formation & geological history

Formed through the deposition of sand or silt in low-energy environments like river deltas, lakes, or floodplains. The organic material is compressed over millions of years, leaving a carbon film or impression.

Uses & applications

Scientific study, educational specimens, and amateur fossil collecting.

Geological facts

Plant fossils like this are often found in coal-bearing strata. They provide vital clues about paleoclimates and the evolution of terrestrial ecosystems during periods like the Carboniferous or Cretaceous.

Field identification & locations

Look for flat planes of breakage (bedding planes) in sedimentary basins. Identifying localized carbon dark spots or distinct leaf vein patterns is key for field identification.
