Nearly 100 fossilised dinosaur eggs dating back to the Jurassic and Cretaceous periods have been unearthed in central China's Hubei province.

The eggs were discovered by workers during the construction of the expressway that runs through Jinyin Mountain in Yunxi County of the province.

Among the first group of 14 fossilised dinosaur eggs discovered at the construction site, 11 were interlocked.

The eggs were pale blue and buried four metres deep, said Wu Xianzhu, a researcher with the Hubei Provincial Research Institute of Cultural Relics and Archaeology said.

Local palaeontologies confirmed the site, which covers 5,000 square metres, to be an important region full of fossilised dinosaur eggs and ordered stoppage of construction works. Excavation work in the region has started.
