Dinosaur eggs are widely available around the world, although those who carry embryos are extremely rare. This greatly limited our understanding of dinosaur development, which is why there are so many mysteries that paleontologists need to unravel.
A new dinosaur embryo fossil that was discovered in China''s southwest Jiangxi province might be able to assist.
Scientists from the Fujian Science and Technology Museum and the China University of Geosciences discovered the discovery in a study published in the journal BMC Ecology and Evolution, which was co-authored by experts from China and Canada on May 8, 2022.
Hadrosaur embryodiscovered in China
The fossil, according to researchers, belongs to the hadrosaurus species, also known as duck-billed dinosaurs. It''s a type of enormous herbivore dinosaur that lived towards the end of the dinosaur period, and while it''s not the first time such an embryo has been discovered, the Ying Baby is by far the best-preserved one yet.
While working on a construction project in the Ganzhou Basin, Jiangxi Province, China, a clutch of subspherical dinosaur eggs was discovered. "At least two of the eggs have identified hadrosauroid embryos, according to the researchers for the first time.
The Yingliang Stone Natural History Museum in East China''s Fujian Province, where the embryo is currently held, has named the specimen the "Ying Baby," and the egg is an ellipsoide with a diameter of approximately 9 centimeters. One of the most important new findings on dinosaur development is that the tiny size of both the egg and the embryo implies that duck-billed dinosaurs had smaller eggs and late body development as a primary feature.
In December 2021, a similar organization discovered a branch of embryo fossils, including an oviraptorosaur embryo fossil. Those researchers examined the embryo fossils, which are extremely rare in nature as the most prevalent animals fade away inside their eggs, and they should provide further information for the study of dinosaurs'' reproductive development, behavior, evolution, and paleoecology. There are still plenty of other sources to explore.
