    Fossil eggs and Cenozoic continental biostratigraphy of Namibia
    (Bernard Price Institute for Palaeontological Research, 1995) Senut, Brigitte; Pickford, Martin
    One kind of aepyornithoid and six kinds of struthious eggshells have been found in Cenozoic deposits of Namibia. Field evidence indicates that the six struthious egg types are time successive, and they thus form a useful basis for determining the relative stratigraphic positions of sites at which they occur. Their placement in the geological time scale has been partly tied down by reference to the biostratigraphic position of mammals that occur in association with them.

    Karoo supergroup palaeontology of Namibia and brief description of a Thecodont from Omingonde
    (Bernard Price Institute for Palaeontological Research, 1995) Pickford, Martin
    Karoo strata crop out extensively in Namibia. Numerous and diverse fossils have been collected from three areas - Karasberg, Kalahari and Huab Karoo basins. Although a great deal of research has been done on these strata and their fossil content, the literature is scattered and no publication has been devoted to a detailed review of what has been achieved. This paper presents a review based principally on a literature search allied to personal experience of some of the fossils and field trips to a few localities. It cannot pretend to be an in-depth review. The Namibian Karoo outcrops are so extensive and the palaeontological remains so diverse, that several years of intensive research would be required to achieve such a work. Tragically, many of the fossils mentioned in the text have been lost or their whereabouts are unknown. A small sample of fossils is housed in the Geological Survey Museum, Windhoek, and other fossils are known to be curated by the South African Museum, Cape Town, the Bernard Price Institute for Palaeontological Research, Witwatersrand University and the Geological Survey of South Africa, Pretoria. A thecodont from the Omingonde Formation (Upper Triassic) is described briefly.
