During the past eight years, palaeontologists participating in a programme of research called Paleokarst Afrique, have been examining karst fillings in Botswana, Angola and Namibia. Numerous richly fossiliferous occurrences have been discovered in all three countries, ranging in age from middle Miocene to Holocene. Preliminary analyses of the fossils indicates that the southern portion of Africa was home to primates throughout this time period, as well as to a host of micromammals and other vertebrates, many of which are new to science.
