Two bone fragments from the Abri Cellier rock shelter in the Dordogne, France, each carved along one edge with a long, regular series of parallel notches. Excavated in 1927 by the Logan Museum of Anthropology's George Collie, Abri Cellier is one of several Aurignacian sites in southwest France — alongside Abri Blanchard and La Marche — whose notched bones have been read as early notational or tallying sequences.
