Abstract

Dark glauconitic shales and overlying calcareous mudstones and siltstones in an exposure (here described as the Alcabala section) near Puerto La Cruz are correlative with the middle and upper part of the Vidono formation and contain an abundant fauna of calcareous and arenaceous foraminifers (86 species). The benthonic assemblage is upper Cretaceous in aspect but contains many forms which range into the lower Eocene. The planktonic assemblage, considered more suitable for correlation and age determination, indicates that the beds are upper Paleocene (Landenian) to lower Eocene (Ypresian) in age.
