The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
Modern, giraffe-like restoration in the MEPAN Outdated moose-like restoration Museum reconstruction Sivatherium resembled the modern okapi , but was far larger, and more heavily built, being about 2.2 m (7.2 ft) tall at the shoulder , 3 m (9.8 ft) in total height with a weight up to 400–500 kg (880–1,100 lb). [ 5 ]
Seven other extinct species of Giraffa are known from the fossil record. The giraffe's distinguishing characteristics are its extremely long neck and legs, horn-like ossicones, and spotted coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi.
The current IUCN taxonomic scheme lists one species of giraffe with the name G. camelopardalis and nine subspecies. [1] [7] A 2021 whole genome sequencing study suggests the northern giraffe as a separate species, and postulates the existence of three distinct subspecies, [8] and more recently, one extinct subspecies.
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)
Samotherium major (middle) in comparison with the okapi (below) and giraffe. The anatomy of Samotherium appears to have shown a transition to a giraffe-like neck. S. major and S. boissieri. A 2015 study found that Samotherium had a neck intermediate in length between the giraffe and the okapi, judging from examination of specimens of S. major ...
A giraffe feeding experience at a Texas wildlife center turned frightening last week when one of the animals hoisted a toddler from the bed of the pickup truck she was riding in.
Giraffatitan (name meaning "titanic giraffe") is a genus of sauropod dinosaur that lived during the late Jurassic Period (Kimmeridgian–Tithonian stages) in what is now Lindi Region, Tanzania. Only one species is known, G. brancai , named in honor of German paleontologist Wilhelm von Branca , who was a driving force behind the expedition that ...
