On the morning of July 14th, there was the donation ceremony of “Oviraptorosaurian with a Pair of Eggs Inside” from Mr. Feng Zhengxiong, director of Taiwan Kiko's Fossil & Mineral Museum to Zhejiang Museum of Natural History (ZMNH).
Dr. Jin Xingsheng, vice-curator of ZMNH, gave a short speech to introduce oviraptorosaurian with a pair of eggs inside. The specimen, coming from Ganzhou, Jiangxi province, China from Upper Cretaceous Nanxiong Formation, was the first dinosaur fossil with a pair of eggs inside. The fossil was the direct evidence of dinosaur’s breeding in the form of laying eggs, proving not only that the oviraptorosaurian has double birth canals, but also their way of laying eggs as well as the crucial proofs to distinguish their sex determination.
The study of the fossil was published in Science. Dr. Jin Xingsheng then drew a comparison between the specimen and the oviraptorosaurian fossil with a pair of eggs inside from Ganzhou in 2012. These two specimens have been known the solely collected dinosaur fossils with eggs, which plays a significant role in studying dinosaur breeding.
