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)
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).
The name "giraffe" has its earliest known origins in the Arabic word zirāfah (زِرَافَةْ), of an ultimately unclear Sub-Saharan African language origin. [2] The Middle English and early Modern English spellings, jarraf and ziraph, derive from the Arabic form-based Spanish and Portuguese girafa. [3]
Angolan giraffe (G. g. angolensis), also known as Namibian giraffe Is found in northern Namibia , south-western Zambia , Botswana , and western Zimbabwe . A 2009 genetic study on this subspecies suggests the northern Namib Desert and Etosha National Park populations each form a separate subspecies. [ 8 ]
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.
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 ...
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.
The Geiseltal fossil deposit is located in the former lignite district of the Geiseltal south of the city of Halle in Saxony-Anhalt, Germany. It is an important site of now extinct plants and animals from the Middle Eocene period 48 to 41 million years ago.
