Two egg fossils containing identifiable hadrosaur embryos have been discovered in the city of Ganzhou, east China's Jiangxi Province, scientists said.

The fossils, which date back to 66 to 72 million years ago, are now preserved at the Yingliang Stone Natural History Museum in Fujian Province.

The better-preserved egg has the shape of a prolate spheroid, with a total volume of approximately 660 ml. The embryo fills about 40 percent of the egg's area.

A paper on the finding, co-authored by researchers in China and Canada, has been published in the journal BMC Ecology and Evolution.

While hadrosaur embryo fossils have been discovered before, the two found in Ganzhou are so far the best-preserved of their kind, according to the research team.
