A long-lived riverine archaeological tradition ('Ribereños Plásticos') of fisher-hunter-gatherer communities along the lower Paraná, lower Uruguay, and Río de la Plata confluence — the Paraná Delta and adjoining floodplains of Entre Ríos, Santa Fe, and Corrientes provinces, Argentina — named for type localities near Goya (Corrientes) and Malabrigo (Santa Fe). Known for cordelled/modeled pottery with zoomorphic (bird-head) decoration; some researchers propose an Arawakan cultural affiliation.
In its late phase the tradition is identified with the historic Chaná-Timbú peoples encountered by the first 16th-century Spanish explorers of the Paraná/Río de la Plata region; it persisted into early European contact before disruption by colonization.
