Identifying the chaîne opératoireof club-rush (Bolboschoenus glaucus(Lam.) S.G.Sm) tuber exploitation during the Early Natufian in the Black Desert (northeastern Jordan)

•An interdisciplinary approach is used to identify the chaîne opératoireof club-rush tuber exploitation.•20 experimental gathering and processing experiments are carried out and evaluated.•Archaeological and experimental tuber assemblages are compared.•How club-rush tubers were exploited by Early Natufians is determined.
