Foraminíferos bentónicos holocenos del talud de Guyana y Surinam (Atlántico Central): su relación con las masas de agua
The study of two sedimentary Holocene cores from the upper slope of Cuianas (Central West Atlantic) allows for the identification of 139 species of benthic foraminifers. This microfauna is similar to those identified in recent materials from French Guiana and Venezuela. As differences with adjácent...

The study of two sedimentary Holocene cores from the upper slope of Cuianas (Central West Atlantic) allows for the identification of 139 species of benthic foraminifers. This microfauna is similar to those identified in recent materials from French Guiana and Venezuela.
