    New Viverrinae (Carnivora: Mammalia) from the basal Middle Miocene of Arrisdrift, Namibia
    (Bernard Price Institute for Palaeontological Research, 2001) Morales, Jorge; Pickford, Martin; Soria, Dolores; Fraile, Susan
    A new genus and species of viverrid of modern type, Orangic!is gariepensis, is described from the basal Middle Miocene locality of Arrisdrift in southern Namibia. It is the earliest known representative of the subfamily Viverrinae from Africa. Detailed examination of the mongoose-like carnivores of the early Miocene of Africa, hitherto all assigned to the family Viverridae, reveals that none of them are related to this group.

    Carboniferous pycnoxylic woods from the Dwyka Group of southern Namibia
    (Bernard Price Institute for Palaeontological Research, 2001) Bangert, Berthold; Bamford, Marion K
    Glacial deposits of the Dwyka Group between Keetmanshoop and Mariental in southern Namibia have been reinvestigated for palaeontological remains and associated tuff horizons in an attempt to accurately date the deposits. SHRIMP-based dating of juvenile zircons from these tuff horizons provide ages which cumulate in the latest Carboniferous (Gzelian). The pycnoxylic woods Megaporoxylon scherziKrausel and Megaporoxylon kaokense Krausel are described in detail for the first time and are compared with similar permineralised woods from Gondwana. Based on previous fossil wood studies covering the rocks of the main Karoo Basin, these species occur only in the Dwyka and lower Ecca Groups in southern Africa and do not extend to the upper Ecca Group.
