The link between dinosaurs and birds was first proposed by Thomas Henry Huxley in the mid-1800s. The fossil of Sinosauropteryx unearthed in Liaoning in 1996 provided the first evidence of the evolutionary relationship between birds and dinosaurs. Consisting of layers of volcanic and sedimentary rock, the geological formation in Liaoning has yielded an enormous variety of fossilized fish, birds, insects, reptiles shrimps, flowers, mammals and dinosaurs, dating back to the late Jurassic and early Cretaceous periods, 145-120 million years ago. At that time, the region was dotted with freshwater lakes and volcanoes. Animals that died in or fell into the lakes were entombed on the lake bottoms by volcanic ash, which over millions of years petrified.
