Use-Wear on Later Stone Age Microliths from Laga Oda, Haraghi, Ethiopia and Possible Functional Interpretations

Summary Excavations in later Stone Age deposits at Laga Oda rock-shelter near Dire Dawa, Ethiopia, yielded a quantity of microliths which retained signs of edge damage. Experiments were conducted in an attempt to replicate the patterns of edge damage observed on the prehistoric material. Several uses are proposed to which the microliths may have been put: some evidently served as knife-blades, suggesting the cutting of grass.
