Late Paleozoic small foraminifers (endothyrids) from South America (Ecuador and Bolivia)
In the Pangea, small foraminifers (endothyrids) are useful tools for studying the stratigraphy of the late Paleozoic. However, they have been largely ignored in South America. This article reports for the first time their widespread occurrence in the subcontinent and illustrates representatives of 2...
