Blue wildebeest
This species of wildebeest seems to have evolved around 2.5 million years ago. The black wildebeest is believed to have diverged from the blue wildebeest to become a distinct species around a million years ago, in the mid- to late Pleistocene. Fossil evidence suggests that blue wildebeest were quite common in the Cradle of Humankind in the past. Apart from eastern Africa, fossils are commonly found in Elandsfontein, Cornelia, and Florisbad.
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.
