It had been argued that the so-called ossicones known from fossils were actually horns, but later research showed that these structures are consistent with the ossicones of giraffes and okapi. [6] The following is a list of some ossicone-bearing genera: Giraffidae †Bramatherium (2 pairs) †Decennatherium (1 pair) Giraffa (giraffes; 1 pair)
Horns from cattle, water buffalo, and sheep are all used for commercial button making, and of other species as well, on a local and non-commercial basis. Horn combs were common in the era before replacement by plastic, and are still made. Horn needle cases and other small boxes, particularly of water buffalo horn, are still made.
Particularly stable giraffe groups are those made of mothers and their young, [91] which can last weeks or months. [99] Young males also form groups and will engage in playfights. However, as they get older, males become more solitary but may also associate in pairs or with female groups.
To understand why giraffes fight we need to take a look at their social hierarchy. Giraffes live in stable family groups with older females helping the mothers to care for the young. A group of ...
Often mistaken with the southern giraffe, the northern giraffe differs by the shape and size of the two distinctive horn-like protuberances known as ossicones on its forehead; they are longer and larger than those of southern giraffe. Male northern giraffes have a third cylindrical ossicone in the center of the head just above the eyes, ranging ...
An adult giraffe head can weigh 30 kg (66 lb), and if necessary, male giraffes establish a hierarchy among themselves by swinging their heads at each other, horns first, a behavior known as "necking". A subordinate okapi signals submission by placing its head and neck on the ground. Giraffes are sociable, whereas okapis live mainly solitary lives.
Male okapis have short, hair-covered horn-like structures called ossicones, less than 15 cm (5.9 in) in length, which are similar in form and function to the ossicones of a giraffe. [28] The okapi exhibits sexual dimorphism , with females 4.2 cm (1.7 in) taller on average, slightly redder, and lacking prominent ossicones, instead possessing ...
After blasting the horn twice, I wait in the dark, suddenly worried that I’ve made a deadly mistake. ... A flock of blue rollers fight over a nesting hole next to a pair of giraffes that look ...
