Black wildebeest
Features necessary for defending a territory, such as the horns and broad-based skull of the modern black wildebeest, have been found in their fossil ancestors. The earliest known fossil remains are in sedimentary rock in Cornelia in the Orange Free State and date back about 800,000 years. Fossils have also been reported from the Vaal River deposits, though whether or not they are as ancient as those found in Cornelia is unclear. Horns of the black wildebeest have been found in sand dunes near Hermanus in South Africa. This is far beyond the recorded range of the species and it has been suggested that these animals may have migrated to that region from the Karoo.
Black and red bush squirrel
The black and red bush squirrel ("Paraxerus lucifer") is a species of rodents in the family Sciuridae occurring in Malawi, Tanzania, and Zambia. In Malawi, it is found in Misuku Hills and Nyika Plateau and in Tanzania Poroto Mountains and Mount Rungwe; it has not been found in Zambia where it was expected to occur in Mafinga Hills and Makutu Mountains. Its natural habitats are subtropical or tropical moist montane forest, subtropical or tropical dry shrubland, and subtropical or tropical dry lowland grassland. It may be threatened by habitat loss.
