Pseudamphimeryx
''Pseudamphimeryx'' is an extinct genus of Paleogene, Palaeogene artiodactyls belonging to the Amphimerycidae that was endemic to the central region of western Europe and lived from the Middle to Late Eocene. It was first erected in 1910 by the Swiss palaeontologist Hans Georg Stehlin, who assigned to it multiple species and noted specific differences from another amphimerycid, ''Amphimeryx''. As of present, it is known by six species, although the validity of ''P. valdensis'' has been questioned while the earliest-appearing species ''P. schosseri'' has been suggested to not be an amphimerycid. ''Pseudamphimeryx'' is very similar to ''Amphimeryx'' with its selenodont (crescent-like ridges) dentition and its fused "cubonavicular bone" (cuboid bone and navicular bone) of its hind legs, both of which are recorded in ruminants in an instance of parallel evolution. Both amphimerycid genera had large orbit (anatomy), orbits and long snouts. ''Pseudamphimeryx'' has very specific diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphimeryx
''Amphimeryx'' is an extinct genus of artiodactyls in the family Amphimerycidae that was endemic to western Europe and lived from the Late Eocene to the Early Oligocene. It was erected in 1848 by the French palaeontologist Auguste Pomel, who argued that its dentition was roughly similar to those of ruminants. The type species, ''A. murinus'', was previously recognized as a species of ''Dichobune'' by the French palaeontologist Georges Cuvier in 1822 before its eventual reclassification into its own genus. Two other species, ''A. collotarsus'' and ''A. riparius'', are purported, although their validity is uncertain. ''Amphimeryx'' is best known for its fused cuboid bone and navicular bone in its hind legs. The fused "cubonavicular bone" is also recorded in derived ruminants including extant ones in an instance of parallel evolution. Additional traits shared by ''Amphimeryx'' with modern ruminants include its middle two digits being fused and its two side digits being greatly red ...

Clive Forster-Cooper
Sir Clive Forster Cooper, FRS (3 April 1880 – 23 August 1947) was an English palaeontologist and Director of the Cambridge University Museum of Zoology and Natural History Museum in London. He was the first to describe ''Paraceratherium'', also commonly known as ''Indricotherium'' or ''Baluchitherium'', the largest known land mammal. Early life He was born on 3 April 1880 in Hampstead, London, the second child and only son of John Forster Cooper and his wife Mary Emily Miley. His maternal grandfather, Miles Miley, was an amateur botanist and naturalist, and encouraged Clive Forster-Cooper in his interest in natural history. He was educated at Summer Fields School, Oxford, Rugby School.'Forster-Cooper, Sir Clive', in ''Who Was Who'' In 1897 he went up to Trinity College, Cambridge, and took a BA in 1901 and MA in 1904. Early career In 1900, Forster Cooper travelled with John Stanley Gardiner to the Maldive and Laccadive Islands to undertake collections and study the formati ...

Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archipelago
An archipelago ( ), sometimes called an island group or island chain, is a chain, cluster, or collection of islands, or sometimes a sea containing a small number of scattered islands. Examples of archipelagos include: the Indonesian Archipelago, the Aleutian Islands, the Lakshadweep Islands, the Galápagos Islands, the Japanese archipelago, the Philippine Archipelago, the Maldives, the Balearic Islands, the Åland Islands, The Bahamas, the Aegean Islands, the Hawaiian Islands, the Canary Islands, Malta, the Azores, the Canadian Arctic Archipelago, the British Isles, the islands of the Archipelago Sea, and Shetland. Archipelagos are sometimes defined by political boundaries. For example, while they are geopolitically divided, the San Juan Islands and Gulf Islands geologically form part of a larger Gulf Archipelago. Etymology The word ''archipelago'' is derived from the Ancient Greek ἄρχι-(''arkhi-'', "chief") and πέλαγος (''pélagos'', "sea") thr ...

Chevrotain
Chevrotains, or mouse-deer, are small even-toed ungulates that make up the family Tragulidae, the only extant members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia, with a single species, the water chevrotain, in the rainforests of Central and West Africa. They are solitary or live in pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between , while the African chevrotain is considerably larger at . With an average length of and an average height of , the Java mouse-deer is the smallest extant (living) ungulate or hoofed mammal, as well as the smallest extant even-toed ungulate. In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (''Tragulus versicolor'') in a Vietna ...

Premolar
The premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps. Premolars can be considered transitional teeth during chewing, or mastication. They have properties of both the canines, that lie anterior and molars that lie posterior, and so food can be transferred from the canines to the premolars and finally to the molars for grinding, instead of directly from the canines to the molars. Human anatomy The premolars in humans are the maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar. Premolar teeth by definition are permanent teeth distal to the canines, preceded by deciduous molars. Morphology There is always one large buccal cusp, especially so in the mandibular first premolar.

Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family ( Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer ( Moschidae) of Asia and chevrotains ( Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in hera ...

Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' ...
