ZONAS DE RADIOLARlOS DEL EOCENO MEDIO DEL GRUPO ANCON, PENINSULA DE SANTA ELENA, ECUADOR
Radiolaria from 504 samples from the Ancón Group at the Anconcito-Punta Mambra section, and from six wells drilled offshore and onshore Santa Elena Peninsula were studied. The following radiolarian Zones of Middle Eocene age were recognized: Dictyoprora mongolfieri, Thyrsocyrtis triacantha, Podocyrt...
