Smallest fossilized non-avian dinosaur egg

The smallest fossilized non-avian dinosaur egg measures 29.93 mm (1.17 in) in length and 22.92 mm (0.90 in) in equatorial diameter and was achieved by Minioolithus ganzhouensis in Ganzhou, Jiangxi, China, on 14 October 2024

This finding was published in the journal Historical Biology on 14 October 2024 by a group of scientists from China. The egg was discovered in the Upper Cretaceous Tangbian Formation of the Ganzhou Basin, Jiangxi Province, South China—one of the world’s richest egg fossil sites. This discovery enhances our understanding of dinosaur egg diversity and theropod evolution during the Late Cretaceous period.
