Miocene Bird egg
Early Miocene (Aquitanian)
France

36mm complete egg with other bird bones on 138mm slab

A complete Miocene bird egg is an incredibly rare fossil find, dating back over 5 to 20 million years. Bird eggs are delicate and fragile, making them unlikely to survive the fossilization process intact. Most fossilized bird eggs are found as broken shells or fragments, so discovering a whole, uncracked egg from the Miocene is extraordinary. It offers a rare window into ancient bird reproduction, nesting behavior, and environmental conditions of the time—a fragile time capsule from a vanished world.
