摘要：
The Paraglossograptus tentaculatus Biozone from the Sierra de La Invernada Formation, western Precordillera of Argentina, is recognized. This biozone is divided into a lower part and an upper part based on their associations. The outcrops suggest an Upper Arenig - Lower Llanvirn age. The vertical distribution of the taxa, fossil associations, local and intercontinental correlation, and the palaeogeographic aspects are discussed.
