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 wallaroo
The black wallaroo ("Macropus bernardus"), Bernard's wallaroo or Woodward's wallaroo, is a species of macropod restricted to a small, mountainous area in Arnhem Land, Northern Territory, Australia, between South Alligator River and Nabarlek. It classified as near threatened, mostly due to its limited distribution. A large proportion of the range is protected by Kakadu National Park.
