Palaeontology and biostratigraphy of the late Palaeozoic Copacabana Group at the Angosto del Beu, Bolivia

The Copacabana Group at the Angosto del Beu, northwestern Bolivia, yielded abundant invertebrates together with fusulinids and palynomorphs that suggest an early Late Carboniferous-Early Permian age for the unit. The lower section f the group contains the fusulinid Millerella extensa Marshall, and i...
