Twenty-six lithic artifacts were uncovered in the same loess sedimentary deposit as the cranium from the Gongwangling site in Lantian County, China. The artifacts consisted of cores, flakes, choppers, hand-axes, spheroids, and scrapers. Lab analysis suggested that the "early hominins chose quartzite, quartz, greywacke and igneous rock pebbles/cobbles on the riverbank for stone knapping, whereas the fine sandstone, siliceous limestone and chert were used only occasionally." Studying the assemblage from Gongwangling along with a series of other sites in the Lantian region leads researchers to believe that the tools utilized by the hominids are more similar to the Acheulean tools utilized in the West than previously thought. This means that the tool technology is not different, and still consists of more large hand tools e.g. hand-axes than previous researchers thought and represents a continuum of technology from the West rather than two separately occurring technologies.
