Acinonyx Kurteni
"''Acinonyx kurteni''", or the Linxia cheetah, is a discredited fossil specimen of an extinct cheetah discovered in China. The scientific name was assigned for the skull that was originally described to be that of an extinct species of cheetah, endemic to Asia during the Late Pliocene sub-epoch. It was estimated to have lived around 2.2 to 2.5 Ma BP, existing for approximately . The fossil discovery was reported in 2008, and was claimed to be the most primitive ''Acinonyx'' lineage so far discovered. Further, the study concluded that the cheetahs originated in the Old World, not the New World as previously believed. It was thought to share some features with the modern cheetah, ''Acinonyx jubatus'', such as in having enlarged sinuses for air intake during sprinting, while its teeth show primitive features. After a long suspicion of the authenticity of the fossil, it was finally accepted as a forgery in 2012. Discovery and description The fossil skull was discovered in 200 ...

Acinonyx Kurteni BW
''Acinonyx'' is a genus within the cat family. The only living species of the genus, the cheetah (''A. jubatus''), lives in open grasslands of Africa and Asia. Several fossil remains of cheetah-like cats were excavated that date to the late Pliocene and Middle Pleistocene. These cats occurred in Africa, parts of Europe and Asia about 10,000 years ago. Several similar species, classified in the genus ''Miracinonyx'', lived in North America at the same time; these may have been more closely related to the genus ''Puma''. Taxonomy ''Acinonyx'' was proposed by Joshua Brookes in 1828. Between the late 18th century and the early 20th century, the following ''Acinonyx'' species and subspecies were described: * ''Felis jubatus'' by Johann Christian Daniel von Schreber in 1777 was based on earlier descriptions by Comte de Buffon and Thomas Pennant. ** ''Felis venatica'' by Griffith in 1821 was based on a sketch of a cheetah from India. ** ''Cynailurus soemmeringi'' by Fitzinger i ...

Proofreading
Proofreading is the reading of a galley proof or an electronic copy of a publication to find and correct reproduction errors of text or art. Proofreading is the final step in the editorial cycle before publication. Professional Traditional method A "galley proof" (familiarly, "a proof") is a typeset version of copy or a manuscript document. It may contain typographical errors ("printer's errors"), as a result of human error during typesetting. Traditionally, a proofreader looks at an increment of text on the copy, compares it to the corresponding typeset increment, and then marks any errors (sometimes called "line edits") using standard proofreaders' marks. Unlike copy editing, the defining procedure of a proofreading service is to work directly with two sets of information at the same time. Proofs are then returned to the typesetter for correction. Correction-cycle proofs will typically have one descriptive term, such as "bounce", "bump", or "revise" unique to the depa ...

Acinonyx Pardinensis
The giant cheetah (''Acinonyx pardinensis'') is an extinct felid species that was closely related to the modern cheetah. Description The lifestyle and physical characteristics of the giant cheetah were probably similar to those of its modern relative, except the giant cheetah was the height of a lion at the shoulder (but, due to its light build, weighed considerably less). It was roughly twice the size of today's cheetahs, putting it at around , and about from head to rump, not including a tail. Its reconstructed shoulder height was at . Like the modern cheetah, the giant cheetah was likely to have been a sprinter, but based on its proportions, was probably slower than the modern cheetah species. Just as with the modern cheetah, almost every aspect of ''Acinonyx pardinesis'' was specialized for running, though not as fast. The muzzle is short and the nasal passage large for increased air intake during a strenuous sprint. To make room for the enlarged nasal passage, the ma ...

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.

Anterior Nasal Aperture
The piriform aperture, pyriform aperture, or anterior nasal aperture, is a pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose. It is bounded above by the inferior borders of the nasal bones; laterally by the thin, sharp margins which separate the anterior from the nasal surfaces of the maxilla; and below by the same borders, where they curve medialward to join each other at the anterior nasal spine The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark. The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxill .... References Nose {{musculoskeletal-stub ...

Canine Tooth
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterall ...

Occipital Condyle
The occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the posterior extremities extend back to the level of the middle of the foramen magnum. The articular surfaces of the condyles are convex from before backward and from side to side, and look downward and lateralward. To their margins are attached the capsules of the atlanto-occipital joints, and on the medial side of each is a rough impression or tubercle for the alar ligament. At the base of either condyle the bone is tunnelled by a short canal, the hypoglossal canal. Clinical significance Fracture of an occipital condyle may occur in isolation, or as part of a more extended basilar skull fract ...

Björn Kurtén
Björn Olof Lennartson Kurtén (19 November 1924 – 28 December 1988) was a Finnish vertebrate paleontologist, belonging to the Swedish-speaking minority of his country. Early life and education Kurtén was born in Vaasa. Career He was a professor in paleontology at the University of Helsinki from 1972 up to his death in 1988. He also spent a year as lecturing guest professor at Harvard University in 1971. In ''Not from the Apes'' (1971) Kurtén argued that man's development has been separate from the apes since the Miocene, and that man did not descend from anthropoids, but rather the reverse: He was also the author of a series of books about modern man's encounter with Neanderthals Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an Extinction, extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ag ..., such as '' Dance of the Tiger'' ( ...
