TAXONOMY

We present systematic data (descriptions, synonymies, biogeographic, paleoecologic and stratigraphic ranges) that were assembled from primary research, from the micropaleontological literature, and from consultation with specialists. The taxonomic classification follows Loeblich and Tappan (1987) with a few exceptions which mainly reflect taxonomic updates published subsequently. The revised timescale of Berggren et al. (1995) was used for the Cenozoic, and the timescale of Gradstein et al. (1995) was used for the Mesozoic.
