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)
True horns are found mainly among: Ruminant artiodactyls. Antilocapridae ; Bovidae (cattle, goats, antelopes etc.). Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones. Cervidae: Most deer have antlers, which are not true horns due to lacking a bone core and made of keratin.
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.
Ossicones are horn-like (or antler-like) protuberances found on the heads of giraffes and male okapis. They are similar to the horns of antelopes and cattle save that they are derived from ossified cartilage, [66] and that the ossicones remain covered in skin and fur rather than horn. Pronghorn cranial appendages are unique. Each "horn" of the ...
The three subspecies of northern giraffe officials are proposing to be listed as endangered include the West African, Kordofan and Nubian giraffes, whose populations have plummeted by roughly 77% ...
Interesting facts for adults. Australia is wider than the moon. ... Giraffe tongues can be 20 inches long. Shrimp’s hearts are located in their heads. Interesting facts.
The northern giraffe (Giraffa camelopardalis), also known as three-horned giraffe, [2] is the type species of giraffe, G. camelopardalis, and is native to North Africa, although alternative taxonomic hypotheses have proposed the northern giraffe as a separate species. [3] [1]
The U.S. Fish and Wildlife Service has proposed new protections for giraffes, saying their populations are threatened by poaching, habitat loss and climate change. Giraffes need endangered species ...
