Benthic foraminifera in the Lower Cretaceous sediments had showed their importance as biostratigraphic tools because their worldwide distribution (e.g. Bettenstadt and Wicher 1955), similar stratigraphic positions (e.g. Bartenstein 1979) and their correlation with other stratigraphic tools (e.g. ammonites). The study of the sediments of Lower Cretaceous age in northern South America had allowed the description of important benthic foraminifera assemblages specifically in Trinidad (e.g. Bartenstein et al. 1957) and eastern Venezuela (Guillaume et al. 1972). However, the thick sedimentary sequences of western Venezuela and Colombia had been systematically discarded to foraminiferal studies, including regional works such as Bolli et al (1994) with few exceptions (e.g. Petters 1954; Rod and Maync 1954). This work illustrates new reports of the benthic foraminifera Epistomina caracolla joined of the ammonite genus Pseudohaploceras, Pedioceras, Nicklesia, Pulchellia and Karsteniceras in several localities in Colombia with an age designation of early Barremian. This new data allow us the discussion of the biostratigraphy based on benthic foraminifera and achieve us to illustrate a “state of art” of these schemes. Some interesting contradictions in the stratigraphic ranges of the foraminifera and the future “work to do” in the area are discussed too. Bartenstein, H.

What´s next? • Re-sampling of locations from Maync (1949) and Petters (1954) • Sampling of more Barremian outcrops in Eastern Cordilleran (e.g. Santander) • Sampling of lower Cretaceous outcrops in Central Cordilleran (Quebradagrande Complex) • Sampling of lower Cretaceous outcrops in northern Guajira (Yuruma Group) • High resolution biostratigraphy? (e.g. isotopes)
