Physical properties

Hardness varies from 5.5 to 7 on the Mohs scale depending on the replacing minerals. Colors include brown, red, black, and tan, with a dull to vitreous luster.

Formation & geological history

Formed through permineralization, where groundwater rich in minerals like silica replaces organic bone material over millions of years, typically dating from the Mesozoic Era.

Uses & applications

Valued primarily as a collector specimen, for educational displays, and occasionally cut and polished into jewelry or decorative lapidary items.

Geological facts

Famous specimens often preserve cellular structures that can be analyzed under a microscope. Dinosaur bone fossils are found globally in sedimentary rock formations.

Field identification & locations

Identify in the field by porous bone texture, characteristic cellular matrix, and distinct fractures embedded within sedimentary layers. Look in ancient river or floodplain deposits.
