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.
Wildebeest
Dutch settlers first "discovered" wildebeest in about 1700, on their way to the interior of South Africa. Due to their resemblance to wild cattle, these people called them "wild ox" or "wildebeest". The blue wildebeest was first known to westerners in the northern part of South Africa a century later, in the 1800s.
