Two sets of dinosaur fossils from the Jurassic period have been discovered in southwest China’s Yunnan Province. They are believed to date back more than 180 million years ago.

Real life Jurassic Park uncovered as scientists find DINOSAUR fossils hidden underground

A team of experts carrying out a six-year survey in east China’s Zhejiang Province have shared their incredible findings.
They found 82 fossil sites and 25 types of eggs during the excavation between 2006 and 2013.
Scientists from the Zhejiang Institute of Hydrogeology and Engineering Geology and the Zhejiang Museum of Natural History worked together on the research.
They used a range of techniques from geology and paleobiology to chronostratigraphy which identifies the deposition of rocks.
Experts also combined site inspections and excavations to scour the site in minute detail.
The survey covered a vast area of 11,000 square kilometres [around] the province’s capital Hangzhou.
Jin Xingsheng, deputy curator of the Zhejiang Museum of Natural History, said: “It has been proved that a large quantity of dinosaurs lived in Zhejiang during the Cretaceous period, about 65 million to 145 million years ago.
“Compared with other southeastern provinces, Zhejiang has the largest amount of dinosaur fossils.”
The researchers’ new findings also provide evidence that a comet or asteroid was responsible for wiping out the dinosaurs.
Scientists discovered the sedimentary rocks, where most of the fossils were discovered, were encased by layers of volcanic rocks. Experts studying the volcanic Deccan Traps recently revealed new details of a double disaster which could have been responsible for the dinosaur extinction.
Their findings show two plumes of magma could have combined with a devastating asteroid hit to ravage the Earth 65 million years ago.
