Physical properties

Hardness varies by mineral replacement, typically Mohs 5-7; colors range from brown to tan; dull to waxy luster; amorphous crystal structure replacing original organic material.

Formation & geological history

Formed through permineralization where minerals like calcite or silica replace organic eggshell and internal structures over millions of years.

Uses & applications

Prized by collectors, museums, and educational institutions for display and paleontological study.

Geological facts

Dinosaur eggs provide crucial insights into prehistoric reproductive behavior, embryonic development, and nesting habits. Notable finds occur globally in Cretaceous and Jurassic strata.

Field identification & locations

Identified by distinctive spherical or elongated shapes with textured, pebbled external shell surfaces. Common locations include China, Argentina, and the western United States.
