Leptoptilos Lüi
''Leptoptilos lui'' is an extinct species of large-bodied stork that existed during the Middle Pleistocene. Along with ''Aegypius jinniushanensis'', ''L. lui'' is one of several new species of extinct birds discovered at Jinniushan, Liaoning, China. The extinct stork is named after Professor Zun-e Lu. When described, the name was spelled as ''Leptoptilos lüi'', however, this violates the rules of the International Code of Zoological Nomenclature, so the correct spelling is ''Leptoptilos lui''. Extant members of the genus ''Leptoptilos'' are today found only found in the African and Asian tropics. ''L. lui'' is the only member of ''Leptoptilos'' from the Pleistocene so far to have been discovered outside of its modern range. Description ''L. lui'' is one of the largest ''Leptoptilos'' on record and might be larger than ''Leptoptilos titan'' and '' Leptoptilos robustus''.

Middle Pleistocene
The Chibanian, more widely known as the Middle Pleistocene (its previous informal name), is an Age (geology), age in the international geologic timescale or a Stage (stratigraphy), stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.7741 annum, Ma (774,100 years ago) and 0.129 Ma (129,000 years ago), also expressed as 774.1–129 ka. It includes the transition in palaeoanthropology from the Lower Paleolithic, Lower to the Middle Paleolithic over 300 ka. The Chibanian is preceded by the Calabrian (stage), Calabrian and succeeded by the Late Pleistocene. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. Its end roughly coincides with the termination of the Penultimate Glacial Period and the onset of the Last Interglacial period (correspondin ...

Stork
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 20 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Ansch� ...

Aegypius Jinniushanensis
''Aegypius'' is a genus of Old World vultures found in the subfamily Aegypiinae. Of the three species in the genus, only the cinereous vulture is extant. The cinereous vulture (''Aegypius monachus'') is a creature that is hard to find as it is “a near threatened raptor that occurs in isolated populations across its range” (Çakmak). There were studies being conducted on the cinereous vulture and it indicates “that the Turkish birds hold, along with those from the Caucasus, an intermediate position between European (Balkan and Iberian) and North Asian (Mongolian) lineages” (Çakmak). The genus name ''Aegypius'' is a Greek word (αἰγυπιός) for 'vulture', or a bird not unlike one; Aelian describes the ''aegypius'' as "halfway between a vulture (''gyps'') and an eagle". Some authorities think this a good description of a lammergeier; others do not. Aegypius is the eponym of the species, whatever it was. The only extant species from this genus is the cinereous v ...

Jinniushan
Jinniushan () is a Middle Pleistocene paleoanthropological site, dating to around 260,000 BP, most famous for its archaic hominin fossils. The site is located near Yingkou, Liaoning, China. Several new species of extinct birds were also discovered at the site. Jinniushan hominin The hominid fossils at Jinniushan all belong to one individual. Initially, the fossils were believed to have belonged to a male specimen, since the fossils were so big. Later analysis shows that the fossil remains actually come from a female specimen. Size The Jinniushan specimen's body mass is estimated to be around , making it the largest female specimen ever discovered in the fossil record. The next largest female specimen ever discovered, found at Grotte du Prince, early Late Pleistocene, from around 100,000 BP, has an estimated body mass of . Body size in ''Homo'' reached its maximum during the Middle Pleistocene, so the size of the Jinniushan specimen is not surprising, especially since the specim ...

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted Convention (norm), convention in zoology that rules the formal scientific name, scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of Binomial nomenclature, binominal nomenclature * How to determine whether a given name is Available name, available * Which available name must be used in case of name conflicts (Valid name (zoology), valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia (other), Abronia'' in both animals and plants). The rules and re ...

Leptoptilos Titan
''Leptoptilos'' is a genus of very large tropical storks, commonly known as adjutants. The name means thin (''lepto'') feather (''ptilos''). Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa. These are huge birds, typically 110–150 cm tall with a 210–250 cm wingspan. The three species each have a black upper body and wings, and white belly and undertail. The head and neck are bare like those of a vulture. The huge bill is long and thick. Juveniles are a duller, browner version of the adult. ''Leptoptilos'' storks are gregarious colonial breeders in wetlands, building large stick nests in trees. They feed on frogs, insects, young birds, lizards and rodents. They are frequent scavengers, and the naked head and neck are adaptations to this, as are those of the vultures with which they often feed. A feathered head would become rapidly clotted with blood and other substances when a scavenging bird's head was i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptoptilos Robustus
''Leptoptilos robustus'' (from reek: thin, slender+ reek: soft featherand atin: strong is an extinct species of large-bodied stork belonging to the genus ''Leptoptilos'' that lived on the island of Flores in Indonesia during the Pleistocene epoch. It stood at about tall and weighed up to an estimated . Due to its large size and presumed flightlessness, L. robustus likely occupied a terrestrial predatory or scavenging niche, possibly competing with Homo floresiensis for food resources.The majority of the discoveries are concentrated in Liang Bua cave located slightly north of Ruteng in the East Nusa Tenggara province. Taxonomy The genus name ''Leptotilos'' is derived from the Greek word meaning "thin or slender", which refers to the stork's slim build and the Greek word meaning "down or soft feather", referring to the soft feather down covering the frame of the members of ''Leptotilos'' stork. The species name, "robustus" is derived from Latin word, meaning "hardness or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humerus
The humerus (; : humeri) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius (bone), radius and ulna, and consists of three sections. The humeral upper extremity of humerus, upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body of humerus, body is cylindrical in its upper portion, and more prism (geometry), prismatic below. The lower extremity of humerus, lower extremity consists of 2 epicondyles, 2 processes (trochlea of the humerus, trochlea and capitulum of the humerus, capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its Surgical neck of the humerus, surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons.

Proximal Phalanx
The phalanges (: phalanx ) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones. Structure The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and big toe, which possess only two. The middle and far phalanges of the fifth toes are often fused together (symphalangism). The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal phalange ...

Pleistocene Birds
The Pleistocene ( ; referred to colloquially as the ''Ice Age'') is the geological epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold glacial periods and warmer interglacials, with the sea levels being up to lower than ...

Extinct Animals Of China
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
