The Quebrada de los Colorados Formation (QLCF) outcrops at the Calchaquíes Valleys (Salta Province, Argentina). Its basal levels were dated in ca. 40 Ma. The specimens here presented were exhumed from QLCF levels at Quebrada Grande, in the area known as Camino de Los Colorados (Los Cardones National Park), below the dated levels and above the contact with the lower section of the Lumbrera Formation (LSLF). In the last revision of the Cingulata from the NWA, Ciancio et al. (2016) unequivocally recognized a single cingulate species, Pucatherium parvum, for these levels. In this work we present a new cingulate association for the QLCF and we analyze its relationship with other NWA associations
