Helladotherium
''Helladotherium'' is an extinct genus of sivatherine giraffid from Europe, Africa, and Asia during the Miocene. The most complete skeleton is that of a female, based on a comparison with an intact female ''Sivatherium giganteum'' skull. Only two species of ''Helladotherium'' have been discovered, with ''H. grande'' being larger than ''H. duvernoyi''. The former has been found only in Pakistan.

Giraffid
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).

Hydaspitherium
''Hydaspitherium'' is an extinct genus of giraffid artiodactyls. Giraffids are represented in the late Miocene of the Siwaliks by large Sivatheriinae such as ''Sivatherium'', ''Bramatherium'', '' Helladotherium'', and ''Hydaspitherium''. ''Hydapitherium'' has been proposed to be synonymous with ''Bramatherium ''Bramatherium'' (Brahma’s beast) is an extinct genus of giraffids that ranged from India to Turkey in Asia. It is closely related to the larger ''Sivatherium''. Etymology The first part of the generic name, Brahma (Sanskrit masculine ', no ...''. ''H. megacephalum'' is restricted to the Dhok Pathan Formation (, paleocoordinates ) in northern Pakistan. Four separate species of ''Hydaspitherium'' were described more than a century ago, but concluded that their differences can be explained as sexual dimorphism and intraspecific variability: ''H. birmanicum'' () is based on a single right upper molar. ''H. grande'' () and ''H. magnum'' (Pilgrim 1910) are only s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
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.

Giraffokeryx
''Giraffokeryx'' is an extinct genus of medium-sized giraffids known from the Miocene of the Indian subcontinent and Eurasia. It is distinguished from other giraffids by the four ossicones on its head; one pair in front of the eyes on the anterior aspect of the frontal bone and the other behind the eyes in the fronto parietal region overhanging the temporal fossae. It has a brachydont dentition like in other giraffids and its legs and feet are of medium length. ''Giraffokeryx'' is considered monotypic by most authors, in the form of ''G. punjabiensis'', but other species have been assigned to the genus: * ''G. chinjensis'' was assigned to the genus, but later included within the extinct species ''Giraffa priscilla''. The distribution of this latter species and ''G. punjabiensis'' indicates that the Himalayas still did not act as a barrier for faunal dispersal during the middle Miocene. * ''G. anatoliensis'', a partial skull with a postorbital horn and isolated teeth from Turk ...

Prehistoric Giraffes
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] |

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.

Sivatherium
''Sivatherium'' ("Shiva's beast", from Shiva and ''therium'', Latinized form of Ancient Greek θηρίον -'' thēríon'') is an extinct genus of giraffids that ranged throughout Africa to the Indian subcontinent. The species ''Sivatherium giganteum'' is, by weight, one of the largest giraffid known, and also one of the largest ruminants of all time. ''Sivatherium'' originated during the Late Miocene (around 7 million years ago) in Africa and survived through to the late Early Pleistocene ( Calabrian) ''S. giganteum'' remains have been recovered from the Himalayan foothills, dating around 1 million years ago. Suggestions have been made that ''S. maurusium'' may have gone extinct as recently as 8,000 years ago, as depictions that resemble it are known from ancient rock paintings in the Sahara and Central West India. But these claims are not substantiated by fossil evidence, and the depictions likely represent other animals. Description ''Sivatherium'' resembled the modern ...

Skeleton
A skeleton is the structural frame that supports the body of an animal. There are several types of skeletons, including the exoskeleton, which is the stable outer shell of an organism, the endoskeleton, which forms the support structure inside the body, and the hydroskeleton, a flexible internal skeleton supported by fluid pressure. Vertebrates are animals with a vertebral column, and their skeletons are typically composed of bone and cartilage. Invertebrates are animals that lack a vertebral column. The skeletons of invertebrates vary, including hard exoskeleton shells, plated endoskeletons, or Sponge spicule, spicules. Cartilage is a rigid connective tissue that is found in the skeletal systems of vertebrates and invertebrates. Etymology The term ''skeleton'' comes . ''Sceleton'' is an archaic form of the word. Classification Skeletons can be defined by several attributes. Solid skeletons consist of hard substances, such as bone, cartilage, or cuticle. These can be further ...

Jean Albert Gaudry
Jean Albert Gaudry (16 September 1827 – 27 November 1908) was a French geologist and palaeontologist. He was born at St Germain-en-Laye, and was educated at the Catholic Collège Stanislas de Paris. He was a notable proponent of theistic evolution.Buffetaut, Éric. (1987). ''A Short History of Vertebrate Palaeontology''. Croom Helm. p. 117 Career At the age of twenty-five he made explorations in Cyprus and Greece, residing in the latter country from 1855 to 1860. He then investigated the rich deposit of fossil vertebrata at Pikermi and brought to light a remarkable mammalian fauna, Miocene in age, and intermediate in its forms between European, Asiatic and African types. He also published an account of the geology of the island of Cyprus (''Mém. Soc. Géol. de France'', 1862). In 1853, while still in Cyprus, he was appointed assistant to Alcide Dessalines d'Orbigny, A d'Orbigny, who was the first to hold the chair of palaeontology in the museum of natural history at Paris.
