Leptoptilos Lüi
''Leptoptilos lüi'' is an extinct species of large-bodied Leptoptilini stork that existed during the Middle Pleistocene. Along with '' Aegypius jinniushanensis'', ''L. lüi'' is one of several new species of extinct birds discovered at Jinniushan, Liaoning, China. The extinct stork is named after Professor Zun-e Lü. Extant members of the genus ''Leptoptilos'' are today found only found in the African and Asian tropics. ''L. lüi'' is the only member of ''Leptoptilos'' from the Pleistocene so far to have been discovered outside of its modern range. Description ''L. lüi'' is one of the largest ''Leptoptilos'' on record and might be larger than '' Leptoptilos titan'' and ''Leptoptilos robustus''. The humerus and proximal phalanx The phalanges (singular: ''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. ... ...

Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an age in the international geologic timescale or a 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 0.770 Ma (770,000 years ago) and 0.126 Ma (126,000 years ago), also expressed as 770–126 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian and succeeded by the proposed Tarantian. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. It ends with the onset of the Eemian interglacial period (Marine Isotope Stage 5). The term Middle Pleistocene was in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). W ...

Stork
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family called 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 19 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 Ans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Leptoptilos Titan
''Leptoptilos'' is a genus of very large tropical storks, also known as the adjutant bird. 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 wa ... [...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 . 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 storks 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 strength". The species name ''robustus'' is a reference to the notably large size of the tibiotarsus and the thickness of its cortex. Debate over the relation between the Liang Bua speci ...

Humerus
The humerus (; ) 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 and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & 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 due to its tendency to fracture, thus often becoming the focus of surgeons. Etymology The word "humerus" is derived from la, humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ''ams'' shoulder and Greek ''ōmos''.

Proximal Phalanx
The phalanges (singular: ''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 large 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 pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleistocene Birds
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 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 grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Extinct Animals Of China
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because 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. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
