- ItemBibliography of Quaternary African palaeontology(Bernard Price Institute for Palaeontological Research, 1969) Welbourne, R. G.The bibliography of Hopwood and Hollyfleld 1954 listed the fruits of African palaeontological research over the 200 years up to the end of 1950. This work is very full and is the basic work in its field. Since it came out, however, only one partial revision had appeared: that of Savage 1956, which merely lists species without giving any references . The work of Hopwood and Hollyfield is now nearly 20 years old and badly needs a supplement. My aim in compiling this bibliography was to meet this need.
- ItemThe use of the Indwe sandstone as a stratigraphic marker in the Molteno stage of the Karroo System(Bernard Price Institute for Palaeontological Research, 1969) Turner, B. R.In recent years it has become increasingly apparent that some of the early concepts of stratigraphic relationships in the Molteno Stage of the Karroo System are not wholly acceptable. Apart from the monotonously repetitive lithology, the lack of' fossil data make regional correlation difficult. Early attempt at correlation were based largely on the supposedly distinctive lithology of certain sandston beds . The Indwe Sandstone , in particular, has received special attention and its general acceptance by stratigraphers as a lithostratigraphic marker of regional significance is now firmly entrenched in the literature.
- ItemUpper Cretaceous calcareous nannoplankton from Zululand, South Africa(Bernard Price Institute for Palaeontological Research, 1969) Richard N PienaarA detailed account of the calcareous nannoplankton occurring in the Upper Cretaceous System of Zululand (Northern Natal) is reported. A total of 58 species are described as seen when studied with the aid of the electron microscope; of these, three are new. These are Zygolithus saggitus, Zygolithus sexiradiatus and Zygolithus siboyus. Using the sequential occurrence of the fossils occurring throughout the sequence studied, it is suggested that the uppermost region is of Maestrichtian age while the lower region appears to be of Campanian age.
- ItemThe evolution of certain upper Cretaceous hystrichospheres from South Africa(Bernard Price Institute for Palaeontological Research, 1969) Davey, Roger J.This paper traces clearly, for the first time, an evolutionary sequence in dinoflagellate cysts. The sedimentary samples containing the cysts are from nnorthern Natal, South Africa, and are of Upper Cretaceous age. The genera concerned in this study are Exochosphaeridium Davey et al. (1966), Cordosphaeridium Eisenack (1963b) and an intermediary genus Amphorosphaeridium nov. Morphological changes exhibited by the cysts are related to ecological considerations and are shown to be directional; their stratigraphic usefulness is also discussed. In all one genus, three species and two varieties are erected.
- ItemLower Karroo (Permlan) Acanthomorphitae Acritarchs from South Africa(Bernard Price Institute for Palaeontological Research, 1969) Hart, George F.Eight populations of fifty individuals of Acritarchs from the Permian marine horizons of South Africa are statistically analysed and assigned to two species of Micrhystridium. The use of the multivariate discriminant function and Mahalanobis-D2 as a taxonomic tool in distinguishing populations and species that have but few measurable variables is briefly discussed and the possibility of using such techniques to determine stratigraphic position in lineage studies noted.
