Vasijas negras pulidas: una variedad de la cerámica tardía del valle Calchaquí

santamariano-calchaquí pottery described for the regional developments period in the calchaquí valley (salta, argentina) is recurrently found in association with pottery that has black polished surfaces. the latter having been scarcely considered, we contrast samples from the la paya site originally produced by ambrosetti (1907), with those obtained from el churcal and quebrada del toro sites, nearby, where similar pottery was found. morphological characterization enabled for the identification of 13 shapes of bowls, pots, bottles and plates. the relative absence of santamariano-calchaquí shapes leads to infer on interregional connections.
