Physical properties

Formation & geological history

If fossil bone, original bone was mineralized as groundwater replaced or filled its tissues with minerals, often over thousands to millions of years; age and setting are unknown.

Uses & applications

Primarily of scientific or educational interest if authenticated; not suitable for jewelry or construction.

Geological facts

Porous fossil bone can resemble weathered rock or modern bone, so appearance alone cannot confirm a fossil.

Field identification & locations

Look for consistent internal bone texture and diagnostic anatomy; professional examination or testing is needed. Fossil bones occur in sedimentary deposits worldwide.
