Abstract

The planktonic foraminifera study using thin sections is relatively recent and in the case of Clavihedbergella simplex and Clavihedbergella moremani species is a method that enhances their observation and identification, even more in cretaceous colombian rocks where traditional peroxide preparation method is not effective. This study provides a taxonomic description of these species using thin section fossils and identifies their occurrence along the cretaceous rocks in a well located in the central part of the Middle Magdalena Valley, Colombia. The guidelines presented in this study validates the usefulness of this investigation method and ease the identification of these two species in thin section.
