Paleontologist Hu Songmei disclosed that one of those discoveries was a bronze pot containing 2,000-year-old dried beef, an early form of beef jerky. The jerky had been resting in its tomb in the village of Wanli since the Warring States Period (475 B.C. – 221 B.C.), and while it had a fuzzy green-black hue due to carbonization, no shrinkage had occurred.
