The discovery of the smallest known dinosaur egg in China has set a new record, shedding light on the evolution of these ancient reptiles. Scientists unearthed six fossilised dinosaur eggs at a construction site in China’s Ganzhou region, known for its rich deposits of fossilised eggs from various ancient reptiles, including dinosaurs. Unlike previous finds in the region that were relatively large, these eggs are exceptionally small, with the smallest measuring just 29mm in length.
After three years of analysis, researchers confirmed that the eggs contain the fossilised remains of dinosaurs that lived around 80 million years ago during the Late Cretaceous era. The eggshells exhibit unique features such as thickness and pores, distinct from any other known dinosaur eggs, indicating they belong to a new species of theropod dinosaurs. The eggs have been classified as Minioolithus ganzhouensis, named after the city where they were discovered.
The findings, published in the journal Historical Biology, mark a significant contribution to our understanding of dinosaur diversity in the Late Cretaceous period. Researchers plan to further investigate the site to learn more about the nesting behaviours and characteristics of the dinosaurs that laid these eggs. This new discovery opens up avenues for exploring the evolution of theropod dinosaurs and their reproductive habits in greater detail.
