Here's just one more fantastic thing about Zigong. There is a fabulous dinosaur dig just minutes from where we will be. The location of the dinosaur fossils were first discovered in 1972. The fossils are from the Meso-Jurassic period, about 160 million years ago. At this location, over 100 dinosaur remains have been excavated, and about 30 of them are complete dinosaur skeletons.
