Physical properties

Hardness varies from 5 to 7 on the Mohs scale due to mineral replacement. Displays porous trabecular bone structure, variable colors, and a dull to vitreous luster.

Formation & geological history

Formed via permineralization where groundwater minerals slowly replace organic bone material over millions of years, typically dating from the Mesozoic Era.

Uses & applications

Valued primarily as a collectible geological specimen, for educational displays, and occasionally cut into cabochons for jewelry.

Geological facts

The cellular structure of the original bone is often preserved microscopically. Bone fossils can absorb your tongue if they are unsealed and porous.

Field identification & locations

Identified by its distinctive honeycomb or porous internal bone texture and dense weight. Commonly found in sedimentary formations globally, such as the Morrison Formation in the US.
