Mined from: Rousset, France

Era: Mesozoic (Late Cretaceous)
Geological Age: ~66–72 mya

Description: These dinosaur eggshell fragments are classified as Cairanoolithus roussetensis, discovered in Rousset, France, and date back to the Late Cretaceous period. The fragments represent pieces of fossilized eggs laid by dinosaurs, preserving the original shell structure including subtle surface textures and pore systems used for gas exchange during incubation. The slightly curved and granular surfaces are characteristic of eggshell material, offering a direct connection to dinosaur reproductive biology.

Formed in sedimentary environments, these eggs were buried and mineralized over tens of millions of years, with the original calcium carbonate structure replaced or reinforced by surrounding minerals. Fossil eggshells like these are important for understanding nesting behavior, species classification, and paleoenvironmental conditions. Even as fragments, they provide valuable insight into dinosaur life cycles and the ecosystems they inhabited.
