The bubal hartebeest, also known as northern hartebeest or bubal antelope or simply bubal (Alcelaphus buselaphus buselaphus) is the extinct nominal (i.e., first described) subspecies of hartebeest. It was formerly found north of the Saharan Desert .
A large antelope with a particularly elongated forehead and oddly shaped horns, the hartebeest stands just over 1 m (3 ft 3 in) at the shoulder, and has a typical head-and-body length of 200 to 250 cm (79 to 98 in). The weight ranges from 100 to 200 kg (220 to 440 lb). The tail, 40 to 60 cm (16 to 24 in) long, ends in a black tuft. [40]
The bluebuck and sable antelope diverged from each other 2.8 million years ago, while the roan antelope diverged from both of them 4.17 million years ago. Africa was going through climatic oscillations between 3.5 and 2 million years ago, and during a colder period, the ancestors of the sable antelope and bluebuck may have been separated, and ...

The subfamily Alcelaphinae (or tribe Alcelaphini), [1] [2] of the family Bovidae, contains the wildebeest, tsessebe, topi, hartebeest, blesbok and bontebok, and several other related species.
These monuments will play a vital role in saving hundreds of plants and animals, many of them unique to these landscapes, like the iconic Joshua Tree, desert bighorn sheep and pronghorn antelope ...
However, many of the causes of amphibian declines are still poorly understood, and the topic is currently a subject of ongoing research. Modeling results found that the current extinction rate of amphibians could be 211 times greater than the background extinction rate. This estimate even goes up to 25,000–45,000 times if endangered species ...
The indigenous fauna of the West Indies collapsed in the Late Quaternary, with the rate of extinction for terrestrial mammals approaching 79-84%, one of the highest in the world. However, in stark contrast to the American continent, radiocarbon dating indicates that mammals survived the end of the Pleistocene with no apparent, or minimal losses ...
