Graecopithecus
''Graecopithecus'' is an extinct species of hominid that lived in southeast Europe during the late Miocene around 7.2 million years ago. Originally identified by a single lower jaw bone bearing a molar tooth found in Pyrgos Vasilissis, Athens, Greece, in 1944, other tooth specimens were discovered from Azmaka quarry in Bulgaria in 2012. With only little and badly preserved materials to reveal its nature, it is considered as "the most poorly known European Miocene hominoids." The creature was popularly nicknamed 'El Graeco' (word play on the Spanish painter El Greco) by scientists. In 2017, an international team of palaeontologists led by Madelaine Böhme of the Eberhard-Karls-University Tübingen, Germany, published a detailed analysis of the teeth and age of the specimens, and came to the conclusion that it could be the oldest hominin, meaning that it could be the oldest direct ancestors of humans after splitting from that of the chimpanzees. Their simultaneous study also cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hominidae
The Hominidae (), whose members are known as the great apes or hominids (), are a taxonomic family of primates that includes eight extant species in four genera: '' Pongo'' (the Bornean, Sumatran and Tapanuli orangutan); '' Gorilla'' (the eastern and western gorilla); '' Pan'' (the chimpanzee and the bonobo); and ''Homo'', of which only modern humans remain. Several revisions in classifying the great apes have caused the use of the term ''"hominid"'' to vary over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans, apes, and their ancestors were considered to be "hominids". The earlier restrictive meaning has now been largely assumed by the term ''" hominin"'', which comprises all members of the human clade after the split from the chimpanzees (''Pan''). The current meaning of "hominid" includes all the great apes including humans. Usage still varies, however, and some scientists ...

Madelaine Böhme
Madelaine Böhme (born 1967) is a German palaeontologist and professor of palaeoclimatology at the University of Tübingen. Böhme was born in 1967 in Plovdiv, Bulgaria. She studied at the Freiberg University of Mining and Technology and Leipzig University, completing her doctorate there in 1997 and habilitation at LMU Munich in 2003. In 2009 she became professor of terrestrial palaeoclimatology in Tübingen. Work published in 2017 by a team including Böhme established that '' Graecopithecus freybergi'' fossils found in Greece were 7.2 million years old and the species was hominin. In 2019, Böhme and her team were the first to describe '' Danuvius guggenmosi'', an extinct species of great apes with adaptations for bipedalism that lived 11.6 million years ago. In 2022, alongside Gerald Mayr and Thomas Lechner, Böhme described '' Allgoviachen tortonica'', a new genus and species of anatid bird from the Hammerschmiede clay pits of Bavaria, Germany Germany, officiall ...

Gustav Heinrich Ralph Von Koenigswald
Gustav Heinrich Ralph (often cited as G. H. R.) von Koenigswald (13 November 1902 – 10 July 1982) was a German-Dutch paleontologist and geologist who conducted research on hominins, including ''Homo erectus''. His discoveries and studies of hominid fossils in Java and his studies of other important fossils of south-eastern Asia firmly established his reputation as one of the leading figures of 20th-century paleo-anthropology. Biography Von Koenigswald was born in Berlin in a period of intense interest and rapid growth in the study of evolution. He began his fossil vertebrate collection when he was fifteen with the acquisition of a rhinoceros molar during an excursion to Mauer, Germany. He subsequently studied geology and paleontology at Berlin, Tübingen, Cologne and Munich. Java Von Koenigswald's teacher Ferdinand Broili had good contacts with the Dutch geologists Karl Martin and Reinout Willem van Bemmelen. Through these contacts Von Koenigswald ...

Homo
''Homo'' () is the genus that emerged in the (otherwise extinct) genus '' Australopithecus'' that encompasses the extant species ''Homo sapiens'' (modern humans), plus several extinct species classified as either ancestral to or closely related to modern humans (depending on the species), most notably ''Homo erectus'' and '' Homo neanderthalensis''. The genus emerged with the appearance of ''Homo habilis'' just over 2 million years ago. ''Homo'', together with the genus ''Paranthropus'', is probably sister to '' Australopithecus africanus'', which itself had previously split from the lineage of '' Pan'', the chimpanzees. ''Homo erectus'' appeared about 2 million years ago and, in several early migrations, spread throughout Africa (where it is dubbed '' Homo ergaster'') and Eurasia. It was likely that the first human species lived in a hunter-gatherer society and was able to control fire. An adaptive and successful species, ''Homo erectus'' persisted for more than a million ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

Queen's Tower (Serpieri)
Queen's Tower ( el, Πύργος Βασιλίσσης, ''Pyrgos Vasilissis'') is a former royal estate near Athens, Greece. The estate, consisting of 200 hectares (494 acres), was purchased by King Otto, the first king of modern Greece. He built there a small neogothic castle for his wife, Queen Amalia. The architecture resembles Hohenschwangau castle in Bavaria, built for Maximilian II of Bavaria, the brother of King Otto. As the castle is only one tower, it is called the Queen's Tower. After the abdication of King Otto, the estate was sold to the Serpieri family, who still own it. They have a dairy farm and wineyard on the estate. The wines bottled on the estate are called "Tour la Reine" (French for Queen's Tower). A nearby station of the Proastiakos The Proastiakos ( el, Προαστιακός; "suburban") is Greece's Commuter rail service, run by Hellenic Train, on rail infrastructure owned by the Hellenic Railways Organisation (OSE) (lines) and GAIAOSE (buildings and ...

Mesopithecus
''Mesopithecus'' ("middle monkey" for being between '' Hylobates'' and '' Semnopithecus'' in build) is an extinct genus of Old World monkey that lived in Europe and Asia 7 to 5 million years ago. ''Mesopithecus'' resembled a modern macaque, with a body length of about . It was adapted to both walking and climbing, possessing a slender body with long, muscular limbs and flexible finger A finger is a limb of the body and a type of digit, an organ of manipulation and sensation found in the hands of most of the Tetrapods, so also with humans and other primates. Most land vertebrates have five fingers (Pentadactyly). Chambers 1 ...s. Its teeth suggest that it primarily ate soft leaves and fruit. It was once thought that these extinct monkeys might be an ancestor of the grey langur, but a study in 2004 suggested that they are more closely related to the snub-nosed monkeys and doucs.

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'' ...

X-ray Microtomography
X-ray microtomography, like tomography and X-ray computed tomography, uses X-rays to create cross-sections of a physical object that can be used to recreate a virtual model ( 3D model) without destroying the original object. The prefix ''micro-'' (symbol: µ) is used to indicate that the pixel sizes of the cross-sections are in the micrometre range. These pixel sizes have also resulted in the terms high-resolution X-ray tomography, micro–computed tomography (micro-CT or µCT), and similar terms. Sometimes the terms high-resolution CT (HRCT) and micro-CT are differentiated, but in other cases the term high-resolution micro-CT is used. Virtually all tomography today is computed tomography. Micro-CT has applications both in medical imaging and in industrial computed tomography. In general, there are two types of scanner setups. In one setup, the X-ray source and detector are typically stationary during the scan while the sample/animal rotates. The second setup, much more like a ...

Enamel Organ
The enamel organ, also known as the dental organ, is a cellular aggregation seen in a developing tooth and it lies above the dental papilla. The enamel organ which is differentiated from the primitive oral epithelium lining the stomodeum.The enamel organ is responsible for the formation of enamel, initiation of dentine formation, establishment of the shape of a tooth's crown, and establishment of the dentoenamel junction. The enamel organ has four layers; the inner enamel epithelium, outer enamel epithelium, stratum intermedium, and the stellate reticulum. The dental papilla, the differentiated ectomesenchyme deep to the enamel organ, will produce dentin and the dental pulp. The surrounding ectomesenchyme tissue, the dental follicle, is the primitive cementum, periodontal ligament and alveolar bone beneath the tooth root. The site where the internal enamel epithelium and external enamel epithelium coalesce is the cervical root, important in proliferation of the dental root. ...
