Nandi bear

In east African folklore, the Nandi bear is a creature said to live in East Africa. It takes its name from the Nandi people who live in western Kenya, in the area the Nandi Bear is reported from. It is also known as Chemosit, Kerit, Koddoelo, Ngoloko, or Duba (which derives from the Arabic words "dubb" or "d.abʕ" / "d.abuʕ" for 'bear' and 'hyena' respectively). The Samburu "Nkampit" appears also to be a version of this creature.
Description.
Descriptions of the Nandi bear are of a ferocious, powerfully built carnivore with high front shoulders (over four feet tall) and a sloping back. Stories of the Nandi bear state that it is fierce, nocturnal, stands on its hind legs and can kill animals. Charles William Hobley authored a diagram of its supposed foot in 1913.
The Nandi people call it "kerit". Local legend holds that the Nandi bear has reddish hair, long feet and is said to scalp people. In 1961, Gardner Soule noted that sightings were reported in Kenya throughout the 19th century and early 20th century but it has "never has been caught or identified". Sightings of the Nandi bear decreased over time. In 1983, Richard Meinertzhagen speculated that it may have been an "anthropoid ape now extinct on account of decreased rainfall."
Scientific evaluation.
There is no scientific evidence that the Nandi bear exists. Alleged sightings are suggested to be misidentification of known species. 
In 1923, Charles William Andrews suggested that the Nandi bear may be a surviving representative of the extinct Chalicothere. In the 1930s Louis Leakey suggested that Nandi Bear descriptions matched that of the Chalicothere, though chalicotheres were herbivores. The Chalicothere hypothesis was later abandoned. In 2000, paleontologist Louis L. Jacobs commented that "if chalicotheres existed now, they would have been found out just like the giant forest hog was." He concluded that "if there is anything to the Nandi-bear story besides imagination, I suspect it may be the word-of-mouth description of gorillas passed across the continent from areas where they live to areas where they do not."
Zoologist Reginald Innes Pocock claimed that reports of the Nandi bear were misidentified hyena, specifically the Spotted hyena. In 1932, the Natural History Museum stated that many reports of the Nandi Bear have "proved to have been nothing more than a spotted hyena." Paleontologist George Gaylord Simpson attributed sightings of the Nandi bear to the honey badger or ratel. Simpson commented that the Nandi bear "turned out to be in most if not all cases a ratel, an animal which had been known to scientific zoologists since 1776."
