Late Cambrian acritarchs from the Santa Rosita Formation: implications for the Cambrian-Ordovician boundary in the eastern Cordillera of northwest Argentina

Marine phytoplankton from the Late Cambrian are described for the first time in the Eastern Cordillera of northwest Argentina. The acritarch assemblage was recovered from an offshore lower mudstone unit towards the base of the Casa Colorada Member (Santa Rosita Formation) in the Quebrada de Moya sec...
