A fossilised dinosaur egg from over 66 million years ago was found to have an embryo inside it, and international researchers say the discovery creates a link between dinosaurs and modern-day birds.

Axar.az reports that the fossilised dinosaur egg was found in 2000 in Ganzhou, Jiangxi Province in southern China by Yingliang Group, a company that mines stones. Company workers suspected they were likely dinosaur fossils, so they were put in storage.

It wasn't until the company began building the Yingliang Stone Nature History Museum in 2010 when museum staff were going through the storage and found the fossils, noticing bones within the egg. After scientists began to examine the fossils, they said one of the eggs contained an embryo, which they named "Baby Yingliang."

Their findings were published in the peer-reviewed journal iScience on Tuesday.
