Resumen:
New acritarch and graptolite data  from the lower to middle Arenig Acoite Formation enable refinement of the biostratigraphic scheme established for the Santa Victoria area of the Eastern Cordillera, northwestern Argentina.The Acoite Formation comprises a thick, shallowing-upward, inner-shelf succession, related to a storm-dominated deltaic system. The Acoite Formation has yielded an abundant macrofauna, mainly composed of trilobites and graptolites. Palynological assemblages have also been recorded. New data are integrated to a   biostratigraphic scheme recently established, involving acritarchs, graptolites and trilobites.
