96 stone tools have been found at Shangchen, including flakes, points, and cores.[6] They were found in 17 artefact layers.[1] The oldest of the tools date to 2.12 million years ago, while the newest date to 1.26 million years, indicating that the site was occupied (not necessarily continuously) for 850,000 years.[2] Some of the tools were found with bone fragments of animals including deer and bovines.[5] Even older remains may still lie undiscovered, as the deepest layers at Shangchen are inaccessible as of 2018 because of farming activities.[2]
