Resumen:
The finding of early conodonts and graptolites in the Acoite Formation outcroping in the Eastern Cordillera at the Quebrada de Los Colorados, Tumbaya Department, Jujuy Province, in the Northwest of Argentina, is mentioned. The conodonts Baltoniodus cf. B. crassulus (Lindström), Drepanoistodus pitjanti Cooper and Drepanoistodus sp. and the graptolites Didymograptus aff. D. simulans Elles & Wood and Didymograptus sp. are described. The graptolites would indicate a Lower Arenigian age and the conodonts suggest a later Lower Arenigian age.
