Palaeotragus
''Palaeotragus'' ("ancient goat") is a genus of very large, primitive, okapi-like giraffids from the Miocene of Africa and Eurasia. ''Palaeotragus primaevus'' is the older species, being found in early to mid-Miocene strata, while ''P. germaini'' is found in Late Miocene strata. ''P. primaevus'' is distinguished from ''P. germaini'' by the lack of ossicones. It was also the smaller species, being a little under at the shoulders. ''P. germaini'' had a pair of ossicones, and in life, it would have resembled either a short-necked, tall giraffe, or a gargantuan okapi. Species The genus consists of the following species: * ''Palaeotragus decipiens'' * ''Palaeotragus germaini'' * ''Palaeotragus microdon'' * ''Palaeotragus primaevus'' * ''Palaeotragus quadricornis ''Palaeotragus'' ("ancient goat") is a genus of very large, primitive, okapi-like giraffids from the Miocene of Africa and Eurasia.

Giraffidae
The Giraffidae are a family of ruminant artiodactyl mammals that share a 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 (one or more species of '' Giraffa'', depending on taxonomic interpretation) and the okapi (the only known species of '' Okapia''). Both are confined to sub-Saharan Africa: the giraffe to the open savannas, and the okapi to the dense rainforest of the Congo. The two genera look very different on first sight, but share a number of common features, including a long, dark-coloured tongue, lobed canine teeth, and horns covered in skin, called ossicones. Taxonomy Evolutionary background The giraffids are ruminants of the clade Pecora. Other extant pecorans are the families Antilocapridae (pronghorns), Cervidae (deer), Moschidae ( musk deer), and Bovidae (cattle, goats and sheep, wildebeests and allies, and antelopes).

Okapi
The okapi (; ''Okapia johnstoni''), also known as the forest giraffe, Congolese giraffe, or zebra giraffe, is an artiodactyl mammal that is endemic to the northeast Democratic Republic of the Congo in central Africa. It is the only species in the genus ''Okapia''. Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae. The okapi stands about tall at the shoulder and has a typical body length around . Its weight ranges from . It has a long neck, and large, flexible ears. Its coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs, and white ankles. Male okapis have short, distinct horn-like protuberances on their heads called ossicones, less than in length. Females possess hair whorls, and ossicones are absent. Okapis are primarily diurnal, but may be active for a few hours in darkness. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ossicone
Ossicones are columnar or conical skin-covered bone structures on the heads of giraffes, male okapi, and some of their extinct relatives. Ossicones are distinguished from the superficially similar structures of horns and antlers by their unique development and a permanent covering of skin and fur. Structure Giraffe ossicones consist of a highly vascularized and innervated bone core covered with vascularized and innervated skin. The base of an ossicone is attached to the skull with vascularized innervated connective tissue. Ossicones are formed at late gestation, but in early development they are not bony and not fused to the skull yet. Ossicones usually fuse to the skull at sexual maturity. All male and female giraffes have a pair of parietal ossicones on the parietal bones of the skull. Males also usually have a single median ossicone on the frontal bone that is larger in northern animals and smaller in southern giraffes. Giraffes can also have small additional paired occipi ...

Miocene Mammals Of Asia
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Prehistoric Even-toed Ungulate Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
