TABLE 2 in How depositional environments impact the preservation of micro-wear of quartz artifacts: insights from the Oldowan of the Shungura Formation (Ethiopia)

TABLE 2. — Synthesis of taphonomic microwear types and their relative abundance,comparing experiments and the depositional environments in the archaeological record. The scale indicates the degree of development of each microwear category: (-) not observed or only present as highly localized traces, and relative abundance (+, present; ++, abundant; +++, very abundant).
