The oldest Ordovician foraminifers (Oepikodus evae conodont Zone, Floian) from South America
The oldest occurrences of the monothalamous foraminifer species. Amphitremoida longa Nestell and Tolmacheva and A. laevis Nestell and Tolmacheva are found in the San Juan Formation together with conodonts of the Oepikodus evae Zone of the Floian (Lower Ordovician), in the Salagasta 2 section, southe...
