Foraminifera from the agrio formation (Lower Cretaceous), neuquén animals in early terrestrial ecosystems. Inbasin, Argentina

Forty-six species of benthic foraminifera recovered from the Pilmatué and Agua de la Mula Members of the the Agrio Formation are described and illustrated. The genus Eomarssonella and Epistomina hechti Bartenstein et al. are recorded for the first time in the Neuquén Basin, and Trocholina infragranu...
