Resumen:
A Tremadocian acritarch assemblage is described from the Santa Rosita
Formation, Cordillera Oriental, Salta Province, northwestern Argentina. The
microplankton corresponds to trilobite bearing strata assigned to the Lower to
Upper Tremadocian from the middle section of the Santa Rosita Formation.The 26 acritarch species comprising the assemblage, are poorly preserved
and not very abundant. Six species have posititive identification, 10 species
have been identified as cf. and 10 species have been left in open nomenclature.The palynological assemblage appears to be related to the Mediterranean
Paleoprovince located along the peripherery of Gondwanaland, thus representing
a high paleolatitudinal microplankton assemblage.
