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 salamander
The black salamander is found in forested areas and grassland in the coastal ranges of south western United States mostly at elevations below but occasionally up to . It has several disjunctive populations. The southernmost population is in the Santa Cruz Mountains. North of this there is a gap where it does not occur and then another population in northern California and southern Oregon. The Black Salamander has a long tail. It has a lot of spots on its tail. In the southern part of its range it hides under logs and rocks in damp places and stream banks in woodland. Northern populations are found in more open country and in the far north of its range it is found among mossy rocks and scree.
