Physical properties
Hardness: 5 (Mohs scale), Color: Dark grey to charcoal black, Luster: Dull to sub-vitreous, Structure: Mineralized organic structure with cortical bone texture, Specific Gravity: 2.5-3.0
Formation & geological history
Formed through the process of permineralization, where organic tissue is replaced by minerals over millions of years. This piece likely dates to the Neogene or Paleogene periods (2.5 to 66 million years ago).
Uses & applications
Educational collections, fossil hunting, and occasionally used in jewelry once polished
Geological facts
The dark color is often a result of phosphate mineralization within marine sediments. Many such fragments are found in coastal regions where ancient seabeds are exposed.
Field identification & locations
Identified by its dense, non-porous feel compared to rocks and the presence of faint organic patterns. Common in peace river or coastal areas of the southeastern United States.
