Physical properties

Hardness varies from 5 to 6 on the Mohs scale depending on mineral replacement. Colors range from tan and brown to reddish-brown, with a dull to earthy luster.

Formation & geological history

Formed through permineralization where groundwater minerals replace organic bone material over thousands to millions of years in sedimentary environments.

Uses & applications

Valued by paleontologists for scientific research and sought after by fossil collectors for display and educational purposes.

Geological facts

Bone fossilization preserves cellular structure microscopically. Famous specimens often reveal details of ancient dinosaur or mammal anatomy.

Field identification & locations

Identify in the field by porous texture, weight, and sometimes distinct anatomical shapes like joints or marrow cavities. Found in sedimentary strata worldwide.
