Phoenicopterus Stocki
''Phoenicopterus stocki'', also known as Stock's flamingo, is an extinct species of flamingo from the Pliocene of Chihuahua, Mexico. It was described in 1944 as a small bodied flamingo species known from assorted fragmentary remains, including bones of the tibia and the wings. The discovery of juvenile remains suggests that the locality where the fossils were found represents a shallow lagoon or mudflat that housed a breeding colony. History The remains of ''Phoenicopterus stocki'' were discovered in the early 20th century by a field party of the California Institute of Technology led by Chester Stock in the Mexican state of Chihuahua. The field party uncovered nine fragments belong to a species of flamingo later described by Loye H. Miller. The type specimen of this taxon was the distal end of a left tibiotarsus, but additional material from various parts of the body have also been referred to this species. This additional material includes the proximal end of a tibia, possi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flamingo
Flamingos or flamingoes () are a type of wading bird in the 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", or a "stand". Etymology The name ''flamingo'' comes from Portuguese or Spanish ; in turn, the word comes from Provençal – a combination of and a Germanic-like suffix ''-ing''. The word may also have been influenced by the Spanish ethnonym or . The name of the genus, ''Phoenicopterus'', is ; other genera names include '' Phoeniconaias,'' which means , and '' Phoenicoparrus,'' which means . Taxonomy and systematics The family Phoenicopteridae was introduced by the French zoologist Charles Lucien Bonaparte in 1831, with '' Phoenicopterus'' as the type genus. Traditionally, the long-legged Ciconiiformes, probably a paraphyletic asse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilean Flamingo
The Chilean flamingo (''Phoenicopterus chilensis'') is a species of large flamingo at a height of closely related to the American flamingo and the greater flamingo, with which it was previously considered a subspecies before being classified as its own species as a result of their lighter color, smaller size and behavioral differences. The species is listed as Near Threatened on the IUCN Red List. The species breeds in South America from Ecuador and Peru to Chile and Argentina and east to Brazil; it has been introduced into Germany. Like all flamingos, it lays a single chalky-white egg on a mud mound. These flamingos are mainly restricted to salt lagoons and soda lakes but these areas are vulnerable to habitat loss and water pollution, especially from mining and irrigation which can cause rapid habitat degradation. Description The Chilean flamingo's plumage is pinker than the slightly larger greater flamingo, but less so than the American flamingo. It can be differen ...

Fossils Of Mexico
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Flying And Gliding Animals
A number of animals are capable of aerial locomotion, either by powered flight or by gliding (flight), gliding. This trait has appeared by evolution many times, without any single common ancestor. Flight has evolved at least four times in separate animals: insects, pterosaurs, birds, and bats. Gliding has evolved on many more occasions. Usually the development is to aid Canopy (biology), canopy animals in getting from tree to tree, although there are other possibilities. Gliding, in particular, has evolved among rainforest animals, especially in the rainforests in Asia (most especially Borneo) where the trees are tall and widely spaced. Several species of aquatic animals, and a few amphibians and reptiles have also evolved this gliding flight ability, typically as a means of evading predators. Types Animal aerial locomotion can be divided into two categories: powered and unpowered. In unpowered modes of locomotion, the animal uses aerodynamic forces exerted on the body due to wi ...

Hildegarde Howard
Hildegarde Howard (April 3, 1901 – February 28, 1998) was an American pioneer in paleornithology. She was mentored by the famous ornithologist, Joseph Grinnell, at the Museum of Vertebrate Zoology (MVZ) and in avian paleontology.Joyce Harvey & Marilyn Ogilvie (2000), ''The Biographical Dictionary of Women in Science'', Volume 1, pp.621 et seq She was well known for her discoveries in the La Brea Tar Pits, among them the Rancho La Brea eagles. She discovered and described Pleistocene flightless waterfowl at the prehistoric Ballona wetlands Ballona Wetlands Ecological Reserve (pronunciation: "Bah-yo-nuh" or "Buy-yo-nah" ) is a protected area that once served as the natural estuary for neighboring Ballona Creek.

Phoenicopterus Copei
''Phoenicopterus copei'' is an extinct species of flamingo that inhabited North America during the Late Pleistocene. Its fossils have been discovered in Oregon, California, Mexico and Florida. Many of these localities preserve the remains of juvenile individuals, indicating that this species nested at the lakes found there. In some areas like California and Florida it coexisted with smaller flamingo species. ''P. copei'' was a large species of ''Phoenicopterus'', described as being greater in size than modern American flamingos. History Although multiple flamingo species are known from North America today, ''Phoenicopterus copei'' was the first fossil taxon of this family described. The species was erected by Robert Wilson Shufeldt in 1891 based on remains discovered at Fossil Lake, Oregon. In 1955 Hildegarde Howard described the remains of two differently sized flamingos from Lake Manix in California, assigning the smaller remains to a new species and the larger to ''Phoenicop ...

Sagittal
The sagittal plane (; also known as the longitudinal plane) is an anatomical plane that divides the body into right and left sections. It is perpendicular to the transverse plane, transverse and coronal plane, coronal planes. The plane may be in the center of the body and divide it into two equal parts (mid-sagittal plane, mid-sagittal), or away from the midline and divide it into unequal parts (para-sagittal). The term ''sagittal'' was coined by Gerard of Cremona. Variations in terminology Examples of sagittal planes include: * The terms ''median plane'' or ''mid-sagittal plane'' are sometimes used to describe the wikt:sagittal plane, sagittal plane running through the midline. This plane cuts the body into halves (assuming bilateral symmetry), passing through midline structures such as the navel and Vertebral column, spine. It is one of the planes which, combined with the umbilical plane, defines the Quadrant (abdomen), four quadrants of the human abdomen. * The term ''parasagi ...

Transverse Plane
A transverse plane is a plane that is rotated 90° from two other planes. Anatomy The transverse plane is an anatomical plane that is perpendicular to the sagittal plane and the dorsal plane. It is also called the axial plane or horizontal plane, especially in human anatomy, but horizontal plane can be misleading with other animals. The plane splits the body into a cranial (head) side and caudal (tail) side, so in humans the plane will be horizontal (dividing the body into superior and inferior sections) but in quadrupeds it will be vertical. Human anatomy Clinically relevant anatomical planes * Transverse '' thoracic plane'' * '' Xiphosternal plane'' (or xiphosternal junction) * '' Transpyloric plane'' * '' Subcostal plane'' * '' Umbilical plane'' (or transumbilical plane) * '' Supracristal plane'' * '' Intertubercular plane'' (or transtubercular plane) * '' Interspinous plane'' Associated structures * The transverse '' thoracic plane'' ** Plane through T4 & T5 verteb ...

Andean Flamingo
The Andean flamingo (''Phoenicoparrus andinus'') is a species of flamingo native to the Andes mountains of South America. Until 2014, it was classified in genus ''Phoenicopterus''. It is closely related to James's flamingo, and the two make up the genus ''Phoenicoparrus''. The Chilean flamingo, Andean flamingo, and James' flamingo are all sympatric, and all live in colonies (including shared nesting areas).Mascitti, V. and Kravetz, F.O., "Bill Morphology of South American Flamingos". ''The Condor''. 104(1), 73. Description It is distinguished from other flamingos by its deeper lower mandible and the very long filtering filaments on the maxilla. It is the largest flamingo in the Andes and is one of the two heaviest living flamingos alongside the taller greater flamingo. Reportedly body mass of the Andean flamingo has ranged from , height from and wingspan from . The flamingo has a pale pink body with brighter upperparts, deep vinaceous-pink lower neck, breast, and wing coverts. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James's Flamingo
James's flamingo (''Phoenicoparrus jamesi''), also known as the puna flamingo, is a species of flamingo that lives at high altitudes in the Andes, Andean plateaus of Peru, Chile, Bolivia, and northwest Argentina. It is named for Harry Berkeley James, a British naturalist who studied the bird. James's flamingo is closely related to the Andean flamingo, and the two species are the only members of the genus ''Phoenicoparrus''. The Chilean flamingo, Andean flamingo, and James's flamingo are all sympatric, and all live in Bird colony, colonies (including shared nesting areas).Mascitti, V. and Kravetz, F.O., "Bill Morphology of South American Flamingos".

Phoenicoparrus
''Phoenicoparrus'' is a genus of birds in the flamingo family Phoenicopteridae. First established by Charles Lucien Bonaparte in 1856, it contains two species. Evolution While it is hard to track where the ''Phoenicoparrus'' originally came from, there is evidence that it originated in the New World where it split from the other lesser group and into its own genus. The base of the genus is hypothesized to have started with the Andean species. The ''Phoenicoparrus'' split from the group around 2.56 million years ago and its two comprising species later split from 0.5-2.5 million years ago. ''Phoenicoparrus'' is identified from the rest of its evolutionary group because it is a part of the deep-keeled group, however it is its own genus because both Andean and Jame's lack a hind toe. Diet and Habitat ''Phoenicoparrus'' chicks are fed filtered secretions from their parents for the first 4-7 weeks of life. The parents are able to filter sediments from the saline concentrated l ...
