Megaceroides Algericus
''Megaceroides algericus'' is an extinct species of deer known from the Late Pleistocene to the Holocene of North Africa. It is one of only two species of deer known to have been native to the African continent, alongside the Barbary stag, a subspecies of red deer. It is considered to be closely related to the giant deer species of Eurasia. Taxonomy The species was first described by Richard Lydekker as ''Cervus algericus'' in 1890 from a maxilla with teeth found near Hammam Maskhoutine in Algeria. The species ''Cervus pachygenys'' was erected for a pachyostotic mandible and an isolated molar found in Algeria by Auguste Pomel in 1892. Léonce Joleaud in two publications in 1914 and 1916 synonymised the two species, and suggested affinities with the giant deer of Europe, and placed it in the newly erected subgenus ''Megaceroides'' within the genus ''Megaceros'' (junior synonym of ''Megaloceros'') as the type species. Camille Arambourg in publications in 1932 and 1938 raised '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...

Praemegaceros
''Praemegaceros'' is an extinct genus of deer, known from the Pleistocene and Holocene of Western Eurasia. It contains the subgenera ''Praemegaceros,'' ''Orthogonoceros'' and ''Nesoleipoceros''. It has sometimes been synonymised with ''Megaloceros'' and ''Megaceroides'', however they have been found to be generically distinct. ''P. obscurus'' is the earliest known species from the Early Pleistocene of Europe, and had long, crooked antlers. ''P. verticornis'' is an Early to Mid-Pleistocene species, closely related to ''P. obscurus'', which lived throughout Southern Europe. The genus was widely distributed across Europe, West and Central Asia during the Early-Middle Pleistocene, with fossils having been discovered in France, Georgia, Germany, England, Greece, Israel, Italy, Romania, Russia Spain, Syria, and Tajikistan. The genus was extinct in mainland Europe and Asia by end of the Middle Pleistocene. An insular species, ''P. cazioti'' survived into the Late Pleistocene and Holocen ...

Rock Art
In archaeology, rock art is human-made markings placed on natural surfaces, typically vertical stone surfaces. A high proportion of surviving historic and prehistoric rock art is found in caves or partly enclosed rock shelters; this type also may be called cave art or parietal art. A global phenomenon, rock art is found in many culturally diverse regions of the world. It has been produced in many contexts throughout human history. In terms of technique, the four main groups are: * cave paintings, * petroglyphs, which are carved or scratched into the rock surface, * sculpted rock reliefs, and * geoglyphs, which are formed on the ground. The oldest known rock art dates from the Upper Palaeolithic period, having been found in Europe, Australia, Asia, and Africa. Anthropologists studying these artworks believe that they likely had magico-religious significance. The archaeological sub-discipline of rock art studies first developed in the late-19th century among Francophone scholar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Elk
The Irish elk (''Megaloceros giganteus''), also called the giant deer or Irish deer, is an extinct species of deer in the genus ''Megaloceros'' and is one of the largest deer that ever lived. Its range extended across Eurasia during the Pleistocene, from Ireland to Lake Baikal in Siberia. The most recent remains of the species have been carbon dated to about 7,700 years ago in western Russia. /nowiki>International_Code_of_Zoological_Nomenclature.html" ;"title="International Code of Zoological Nomenclature">/nowiki>International Code of Zoological Nomenclature">International Code of Zoological Nomenclature">/nowiki>International Code of Zoological Nomenclature/nowiki> (article 12) to validate ''Megalocerus''." The original spelling of ''Megalocerus'' was never used after its original publication.In 1844 Richard Owen named another synonym of the Irish elk, including it within the newly named subgenus ''Megaceros'', ''Cervus'' (''Megaceros'') ''hibernicus''.

Vomer
The vomer (; lat, vomer, lit=ploughshare) is one of the unpaired facial bones of the skull. It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. The vomer forms the inferior part of the nasal septum in humans, with the superior part formed by the perpendicular plate of the ethmoid bone. The name is derived from the Latin word for a ploughshare and the shape of the bone. In humans The vomer is situated in the median plane, but its anterior portion is frequently bent to one side. It is thin, somewhat quadrilateral in shape, and forms the hinder and lower part of the nasal septum; it has two surfaces and four borders. The surfaces are marked by small furrows for blood vessels, and on each is the nasopalatine groove, which runs obliquely downward and forward, and lodges the nasopalatine nerve and vessels. Borders The ''superior border'', the thickest, presents a dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachyostosis
Pachyostosis is a non-pathological condition in vertebrate animals in which the bones experience a thickening, generally caused by extra layers of lamellar bone. It often occurs together with bone densification (osteosclerosis), reducing inner cavities. This joint occurrence is called pachyosteosclerosis. However, especially in the older literature, "pachyostosis" is often used loosely, referring to all osseous specializations characterized by an increase in bone compactness and/or volume. It occurs in both terrestrial and, especially, aquatic or semi-aquatic vertebrates. In aquatic animals, such as seacows (manatees and dugongs), ''Thalassocnus'', and plesiosaurs, pachyostosis in the thoracic region provides (or provided) ballast against the air-filled lungs. This maintains neutral buoyancy in aquatic habitats. Most giant deer showed pronounced pachyostosis of the mandible and skull. It has been suggested that this served to store minerals for antler growth. Many Pachycephalosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parietal Bone
The parietal bones () are two bones in the Human skull, skull which, when joined at a fibrous joint, form the sides and roof of the Human skull, cranium. In humans, each bone is roughly quadrilateral in form, and has two surfaces, four borders, and four angles. It is named from the Latin ''paries'' (''-ietis''), wall. Surfaces External The external surface [Fig. 1] is convex, smooth, and marked near the center by an eminence, the parietal eminence (''tuber parietale''), which indicates the point where ossification commenced. Crossing the middle of the bone in an arched direction are two curved lines, the superior and inferior temporal lines; the former gives attachment to the temporal fascia, and the latter indicates the upper limit of the muscular origin of the temporal muscle. Above these lines the bone is covered by a tough layer of fibrous tissue – the epicranial aponeurosis; below them it forms part of the temporal fossa, and affords attachment to the temporal muscle. ...

Splanchnocranium
The splanchnocranium (or visceral skeleton) is the portion of the cranium that is derived from pharyngeal arches. ''Splanchno'' indicates to the gut because the face forms around the mouth, which is an end of the gut. The splanchnocranium consists of cartilage and endochondral bone. In mammals, the splanchnocranium comprises the three ear ossicles (i.e., incus, malleus, and stapes), as well as the alisphenoid, the styloid process, the hyoid apparatus, and the thyroid cartilage. In other tetrapods, such as amphibians and reptiles, homologous bones to those of mammals, such as the quadrate, articular, columella, and entoglossus are part of the splanchnocranium. See also * Dermatocranium * Endocranium The endocranium in comparative anatomy is a part of the skull base in vertebrates and it represents the basal, inner part of the cranium. The term is also applied to the outer layer of the dura mater in human anatomy. Structure Structurally, t ... References {{anatomy-stub ...

Fallow Deer
''Dama'' is a genus of deer in the subfamily Cervinae, commonly referred to as fallow deer. Name The name fallow is derived from the deer's pale brown colour. The Latin word ''dāma'' or ''damma'', used for roe deer, gazelles, and antelopes, lies at the root of the modern scientific name, as well as the German ''Damhirsch'', French ''daim'', Dutch ''damhert'', and Italian ''daino''. In Croatian and Serbian, the name for the fallow deer is ''jelen lopatar'' ("shovel deer"), due to the form of its antlers. The Modern Hebrew name of the fallow deer is ''yachmur'' (יחמור). Taxonomy and evolution The genus includes two extant species: Extant species Some taxonomists include the Persian fallow deer as a subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed.
