Paraceratheriidae
Paraceratheriidae is an extinct family of long-limbed, hornless rhinocerotoids, native to Asia and Eastern Europe that originated in the Eocene epoch and lived until the end of the Oligocene. They represent some of the largest terrestrial mammals to have ever lived. Description The necks and limbs of paraceratheriids are elongate relative to those of living rhinoceroses. The earliest paraceratheres like '' Juxia'' were comparable in size with living rhinoceroses with a body mass of three quarters to one and a half tons, while later members grew substantially larger, with the largest representatives (''Paraceratherium'', '' Dzungariotherium'') estimated to have a body mass of 17 to possibly over 20 tonnes, making them the largest land mammals to have ever lived (though possibly equalled or exceeded by some proboscideans in body mass). Non-fostercoopine paraceratheriids are united by the possession of a retracted nasal notch, a lack of contact between the premaxilla and nasal bone ...

Rhinocerotoid
Rhinocerotoidea is a superfamily (taxonomy), superfamily of Perissodactyla, perissodactyls that appeared 56 million years ago in the Paleocene. They included four extinct families, the Amynodontidae, the Hyracodontidae, the Paraceratheriidae, and the Eggysodontidae. The only extant family is the Rhinocerotidae (true rhinoceroses), which survives as five living species. Extinct non-rhinocerotid members of the group are sometimes considered rhinoceroses in a broad sense. Although the term 'rhinoceroses' is sometimes used to refer to all of these, a less ambiguous vernacular term for this group is 'rhinocerotoids'. The family Paraceratheriidae contains the largest land mammals known to have ever existed. Taxonomy The cladogram below follows a phylogenetic analysis by Bai ''et al.''

Paraceratherium
''Paraceratherium'' is an extinct genus of hornless rhinocerotoids belonging to the family Paraceratheriidae. It is one of the largest terrestrial mammals that has ever existed and lived from the early to late Oligocene epoch (34–23 million years ago). The first fossils were discovered in what is now Pakistan, and remains have been found across Eurasia between China and the Balkans. ''Paraceratherium'' means "near the hornless beast", in reference to '' Aceratherium'', the genus in which the type species ''P. bugtiense'' was originally placed. The exact size of ''Paraceratherium'' is unknown because of the incompleteness of the fossils. The shoulder height was about , and the length about . Its weight is estimated to have been about . The long neck supported a skull that was about long. It had large, tusk-like incisors and a nasal incision that suggests it had a prehensile upper lip or proboscis (trunk). The legs were long and pillar-like. The lifestyle of ''Paracera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urtinotherium
''Urtinotherium'' (meaning "Urtyn beast" in Ancient Greek) is an extinct genus of paracerathere mammals. It was a large animal that was closely related to ''Paraceratherium'', and found in rocks dating from the Late Eocene to Early Oligocene period. The remains were first discovered in the Urtyn Obo region (now Dorbod Banner, Ulanqab) in Inner Mongolia, which the name ''Urtinotherium'' is based upon. Other referred specimens are from northern China. Description ''Urtinotherium'' was a representative of the large family Paraceratheriidae, and almost reached the proportions of ''Paraceratherium''. ''Urtinotherium'' evolved from Juxia and represents the beginning of paracerathere gigantism. It could reach a weight of about 5 tonnes, and was among the largest animals living in its environment, alongside the brontothere ''Embolotherium''. It is known from several findings in central and eastern Asia, though no complete skeletons are known. The holotype fossil (catalog number IVPP V ...

Juxia
''Juxia'', ‘joo-she-a’, (from ) is an extinct genus of Paraceratheriidae, paraceratheriid, a group of herbivorous mammals that are related to the modern rhinoceros. The type species is ''Juxia sharamurenensis'', named by Zhou Mingzhen and in 1964. ''Juxia'' was around the size of a horse. It lived in Asia during the upper Eocene. As an early paraceratheriid, ''Juxia'' was a relatively small animal compared to its later relatives, with a body mass estimated at or , held by elongated long legs and small skull firmly attached to a relatively long neck. Based on its triangular-like teeth and sharp protruding incisors, ''Juxia'' was probably a strict browser, feeding on ferns and leaves on branches where most herbivorous mammals could not reach. In terms of habitat, ''Juxia'' lived in densely lush and tropical forests of what is now China. Though a few skeletons have been found, it is unclear whether this animal was permanently solitary or lived in small social groups, possibly ...

Forstercooperia
''Forstercooperia'' is an extinct genus of forstercooperiine indricotheriinae, paraceratheriid rhinocerotoids from the Middle Eocene of Asia. Description ''Forstercooperia'' is known from a vast amount of cranial material, although only some scant postcranial remains. The average size of the genus is about equal with a large dog, even though later genera like ''Juxia'' and ''Paraceratherium'' reached sizes of a cow and even much larger. Like primitive rhinocerotoids, ''Forstercooperia'' possesses blunt ends on the tips of its nasals, above the nasal incision. Unlike all modern rhinoceroses, the nasals of ''Forstercooperia'', as well as many related genera, lack rugosities, which suggests that they lacked any form of horn. The nasal incision extends fairly far into the upper jaw, ending just posterior to the canine. ''Forstercooperia'' possesses a small post-insicor diastema, not as large as its descendants, and similar in size to that of ''Hyracodon''. Taxonomy ''Forstercooperia ...

Pappaceras
''Pappaceras'' is an extinct genus of rhinocerotoids from the Early Eocene of Asia belonging to Paraceratheriidae. Taxonomy In 1963 in paleontology, 1963, material including a partial skull containing cheek teeth was unearthed in Late Eocene deposits of Mongolia. These remains were identified as from a true rhinoceros by Wood, who found them an important discovery with the scant amount of previous cranial material of early rhinocerotids available. On July 25, the same year, a paper was published by Wood concerning the taxonomy and osteology of these remains, in which he named them a new genus and species (or binomial) as well as re-ranking a previously named family as a subfamily containing the new taxon. The binomial created was ''Pappaceras confluens'', classified as a close relative of ''Forstercooperia'' within Forstercooperiinae (before Forstercooperiidae, named in 1940 in paleontology, 1940 by Kretzoi). Wood noted that the generic name is derived from the Latin word ''πaπ� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dzungariotherium
''Dzungariotherium'' is a genus of paraceratheriid, an extinct group of large, hornless rhinocerotoids, which lived during the middle and late Oligocene of northwest China. The type species ''D. orgosense'' was described in 1973 based on fossilsmainly teethfrom Dzungaria in Xinjiang, northwest China. Description The teeth of ''D. orgosense'' (from which that species is mainly known) are 25 percent larger than those of '' Paraceratherium transouralicum'', indicating that it was one of the largest known paraceratheriids,Prothero, 2013. pp. 67–86 but the teeth and skull were proportionally large compared to the body, making it smaller overall. Skull length range is 126-143 cm. The mass of a ''D. sp'' specimen was estimated to be ~ 20.6 metric tons. ''Paraceratherium bugtiense'' and ''D. orgosense'' share features such as relatively slender maxillae In vertebrates, the maxilla (: maxillae ) is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the ...

Proboscidea
Proboscidea (; , ) is a taxonomic order of afrotherian mammals containing one living family (Elephantidae) and several extinct families. First described by J. Illiger in 1811, it encompasses the elephants and their close relatives. Three living species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Extinct members of Proboscidea include the deinotheres, mastodons, gomphotheres and stegodonts. The family Elephantidae also contains several extinct groups, including mammoths and '' Palaeoloxodon''. Proboscideans include some of the largest known land mammals, with the elephant '' Palaeoloxodon namadicus'' and mastodon ''"Mammut" borsoni'' suggested to have body masses surpassing , rivalling or exceeding paraceratheres (the otherwise largest known land mammals) in size. The largest extant proboscidean is the African bush elephant, with a world record of size of at the shoulder and . In addition to thei ...

Donald R
Donald is a Scottish masculine given name. It is derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers. A short form of Donald is Don, and pet forms of Donald include Donnie and Donny. The feminine given name Donella is derived from Donald. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name '' Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related.
