Resumen:
ABSTRACTThe trilobite Reedops is documented from beds probably corresponding to the middle part of the Talacasto Formation in the Sierra de las Minitas, at the northernmost extent of the Precordillera in La Rioja Province, northwestern Argentina. The specimens resemble the type species of the genus, R. bronni, indicating a Pragian (Early Devonian) age for the strata, and suggesting the existence at this time of faunal dispersals, particularly between the Malvinokaffric Realm and the Bohemian area of the Old World Realm. The taxon represents the first Early Devonian macrofaunal element in the Malvinokaffric Realm with global biostratigraphical significance.
