‘Baby Yingliang’: unborn dinosaur’s position inside Chinese egg fossil strengthens link with birds, say scientists

• Rare 66-72 million year-old embryo had its head below its body, feet on either side and back curled in a pose not previously recognised in non-avian dinosaurs
• Egg was acquired in 2000 and kept in storage for a decade before being brought to light again during the building of the Yingliang Stone Natural History Museum
