Pelargopappus
''Pelargopappus'' is an extinct genus of raptor related to the secretarybird that lived in early Miocene France. Only one species, the type species ''P. magnus'' is officially recognized. A second species, ''P. schlosseri'' from the mid-and late Oligocene, was split off into the genus '' Amphisagittarius''. French paleontologist Cécile Mourer-Chauviré Cécile Mourer-Chauviré (born 1939) is a French paleontologist specializing in birds of the Eocene and the Oligocene. In her early career, she discovered with her husband the Laang Spean cave site of prehistoric humans in Cambodia. Career Cé ... examined the bones of the two genera and concluded that the distal ends of tibiotarsi and tarsometatarsi were the same and that ''Amphisagittarius'' should be synonymised with ''Pelargopappus'' and supported the placement of the genus in Sagittariidae (rather than the stork family Ciconiidae). She added that ''Amynoptilon'' was also a synonym. References {{Taxonbar, from1=Q8579 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secretarybird
The secretarybird or secretary bird (''Sagittarius serpentarius'') is a large, mostly terrestrial bird of prey. Endemic to Africa, it is usually found in the open grasslands and savanna of the sub-Saharan region. John Frederick Miller described the species in 1779. Although a member of the order Accipitriformes, which also includes many other diurnal birds of prey such as kites, hawks, vultures, and harriers, it is placed in its own family, Sagittariidae. The secretarybird is instantly recognizable as a very large bird with an eagle-like body on crane-like legs that give the bird a height of as much as . The sexes are similar in appearance. Adults have a featherless red-orange face and predominantly grey plumage, with a flattened dark crest and black flight feathers and thighs. It also has very long eyelashes. Breeding can take place at any time of year, but tends to be late in the dry season. The nest is built at the top of a thorny tree, and a clutch of one to three eggs ...

Cécile Mourer-Chauviré
Cécile Mourer-Chauviré (born 1939) is a French paleontologist specializing in birds of the Eocene and the Oligocene. In her early career, she discovered with her husband the Laang Spean cave site of prehistoric humans in Cambodia. Career Cécile Chauviré was born on 5 November 1939 in Lyon, France. She studied at University of Lyon. Her early work was on large Quaternary mammals. She then proceeded in 1961 to a doctorate in Centre national de la recherche scientifique focusing on Pleistocene birds, a topic few at the time studied in France or Europe. Following her marriage in 1964 to Roland Mourer, she relocated to Cambodia where he was assigned by the French military as a "coopérant" in Kampong Chhnang (city), Kampong Chhnang. In 1965 she was appointed as a geology professor at Royal University of Phnom Penh, a post she held until the civil war in 1970. During this time she discovered with her husband the Laang Spean cave site of prehistoric humans.Sophady, Heng, et al. "La ...

Accipitriformes
The Accipitriformes (; from Latin ''accipiter''/''accipitri-'' "hawk", and New Latin ''-formes'' "having the form of") are an order of birds that includes most of the diurnal birds of prey, including hawks, eagles, vultures, and kites, but not falcons. For a long time, the majority view was to include them with the falcons in the Falconiformes, but many authorities now recognize a separate Accipitriformes. A DNA study published in 2008 indicated that falcons are not closely related to the Accipitriformes, being instead more closely related to parrots and passerines. Since then, the split and the placement of the falcons next to the parrots in taxonomic order has been adopted by the American Ornithological Society's South American Classification Committee (SACC), its North American Classification Committee (NACC), and the International Ornithological Congress (IOC). The British Ornithologists' Union already recognized the Accipitriformes, and has adopted the move of Falconiforme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Birds
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
