Presbyornithid
Presbyornithidae is an extinct group of birds with a global distribution. They had evolved by the late Cretaceous period and became extinct during the early Miocene. Initially, they were believed to present a mix of characters shown by waterbirds, shorebirds and flamingos and were used to argue for an evolutionary relationship between these groups, but they are now generally accepted to be waterfowl closely related to modern ducks, geese, and screamers. They were generally long-legged, long-necked birds, standing around one meter high, with the body of a duck, feet similar to a wader but webbed, and a flat duck-like bill adapted for filter feeding. At least some species were social birds that lived in large flocks and nested in colonies, while others, like the ''Wilaru'' species, were terrestrial and solitary. Several genera have been classified as presbyornithids: * '' Presbyornis'' ( type) * '' Bumbalavis'' * '' Headonornis'' (disputed) * '' "Styginetta" * '' Telmabates'' * '' ...

Wilaru
''Wilaru'' is an extinct genus of bird of uncertain phylogenetic placement from the Late Oligocene to Early Miocene of Australia. It was originally classified as a stone-curlew, but subsequently it was argued to be a member of the extinct family Presbyornithidae instead. It is either the oldest known burhinid or the youngest known presbyornithid. The type species is ''Wilaru tedfordi''; genus also includes the second species ''Wilaru prideauxi''. The type species was described from fossil material collected from Lake Pinpa, Lake Palankarinna and Billeroo Creek, in the Lake Eyre Basin of north-eastern South Australia. The genus name ''Wilaru'' is the term for “stone curlew” in the Diyari language of the Lake Eyre region. The specific epithet of the type species honours American palaeontologist Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (rou ...

Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bird ...

Zhylgaia
''Zhylgaia'' is a genus of fossil bird. Its remains, consisting of two partial humeri, were recovered from an upper Paleocene deposit in Kazakhstan. The relationships of this genus are unknown; it was initially placed in the Presbyornithidae, which at that time were believed to be some sort of "transitional shorebird". Upon recognition that the presbyornithids were more likely a prehistoric lineage of fairly advanced waterfowl, ''Zhylgaia'' was assigned to the form taxon " Graculavidae", an assemblage of Late Cretaceous and Paleocene shorebirds which are not a natural clade but merely an assemblage of superficially similar birds. All that can be said about this taxon is that it was a modern bird, most likely a neognath. In 2008, ''Zhylgaia'' was assigned to Prophaethontidae—an extinct family related to modern tropicbirds—on the basis of its anatomy and size closely matching the prophaethontid ''Lithoptila ''Lithoptila abdounensis'' is an extinct species of seabird that ...

Flamingo
Flamingos or flamingoes are a type of Wader, wading bird in the Family (biology), family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia. A group of flamingoes is called a "flamboyance." Etymology The name ''flamingo'' comes from Portuguese language, Portuguese or Spanish language, Spanish ("flame-colored"), which in turn comes from Old Occitan, Provençal – a combination of ("flame") and a Germanic-like suffix ''wikt:-ing#Etymology 3, -ing''. The word may also have been influenced by the Spanish ethnonym ("Fleming" or "Flemish"). The name of the genus, ''Phoenicopterus'', is from the Greek , ); other genera names include ''Lesser flamingo, Phoeniconaias,'' which means "crimson/red Naiad, water nymph (or naiad)", and ''Phoenicoparrus,'' which means "crimson/red bird (though, an unknown bird of om ...

Nemegt Formation
The Nemegt Formation (also known as Nemegtskaya Svita) is a geological formation in the Gobi Desert of Mongolia, dating to the Late Cretaceous. The formation consists of river channel sediments and contains fossils of fish, turtles, crocodilians, and a diverse fauna of dinosaurs, including birds. Description The Nemegt Formation is composed of mudstones and sandstones that were deposited by ancient lakes, streams, and flood plains. The Altan Uul locality was described by Michael Novacek as "a canyon carved out of a very rich series of sedimentary rocks" with "steep cliffs and narrow washes". The climate associated with it was wetter than when preceding formations were deposited; there seems to have existed at least some degree of forest cover. Fossilized trunks have been also found. These petrified wood, and the remains of Araucariaceae conifers indicate that the forests of the Nemegt were thickly wooded, with a high canopy formed by tall conifer trees. When examined, the rock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barun Goyot Formation
The Barun Goyot Formation (also known as Baruungoyot Formation or West Goyot Formation) is a geological formation dating to the Late Cretaceous Period. It is located within and is widely represented in the Gobi Desert Basin, in the Ömnögovi Province of Mongolia. Description It was previously known as the Lower Nemegt Beds occurring beneath the Nemegt Formation and above the Djadokhta Formation. It has been suggested that the Djadokhta and Barun Goyot Formations are lower and upper parts, respectively, of the same lithological unit and the boundary between the two does not exist. The stratotype of the Barun Goyot Formation is the Khulsan locality, east of Nemegt. At Nemegt, only the uppermost barungoyotian beds are visible. The ''Red Beds of Khermeen Tsav'' are also considered part of the Barun Goyot Formation. It is approximately in thickness,Gradzinski, R.; & Jerzykiewicz, T. (1974).

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Scapula
The scapula (plural scapulae or scapulas), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble. In compound terms, the prefix omo- is used for the shoulder blade in medical terminology. This prefix is derived from ὦμος (ōmos), the Ancient Greek word for shoulder, and is cognate with the Latin , which in Latin signifies either the shoulder or the upper arm bone. The scapula forms the back of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage. Structure The scapula is a thick, flat bone lying on the thoracic wall that provides an attachment for three groups of muscles: intrin ...
