The aardwolf (Proteles cristatus [3]) is an insectivorous hyaenid species, native to East and Southern Africa.Its name means "earth-wolf" in Afrikaans and Dutch. [4] [5] It is also called the maanhaar-jackal [6] [7] (Afrikaans for "mane-jackal"), termite-eating hyena [8] and civet hyena, based on its habit of secreting substances from its anal gland, a characteristic shared with the African civet.
Hyenas are known to have preyed on humans in prehistory: human hair has been found in fossilized hyena dung dating back 195,000 to 257,000 years. [68] Some paleontologists believe that competition and predation by cave hyenas ( Crocuta crocuta spelaea ) in Siberia was a significant factor in delaying human colonization of Alaska .
It is a means for comparison, not an indicator of absolute bite force. In short, if an animal or species has a high BFQ this indicates that it bites hard for its size after controlling for allometry. Hite et al., [ 3 ] who include data from the widest range of living mammals of any bite force regression to date, produce from their regression ...
The spotted hyena (Crocuta crocuta), also known as the laughing hyena, [3] is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. [1]
Territories are marked by 'pasting', [23] during which the hyena deposits secretions from its large anal gland, which is located below the base of the tail and produces a black and white paste, on vegetation and boulders. [14] Brown hyenas maintain a stable clan hierarchy through ritualized aggressive displays and mock fights.

For comparison, the wandering albatross has the largest wingspan of living birds at up to 3.5 m (11 ft) but usually weighs less than 12 kilograms (26 lb). This indicates that the largest pterosaurs may have had higher wing loadings than modern birds (depending on wing profile ) and this has implications for the manner in which pterosaur flight ...
A 2017 study estimated that on average cave hyenas weighed approximately 88 kilograms (194 lb), around 60% heavier than living spotted hyenas. In comparison to living spotted hyenas, some of the bones of the limbs are more robust (proportionally thicker and shorter), with the ulna being more curved.
