Phoenicopterus Novaehollandiae
''Phoenicopterus novaehollandiae'' is an extinct species of flamingo from the late Oligocene or early Miocene Etadunna Formation of Australia. It was a large species similar in size to large specimens of the modern greater flamingo, but differs by likely having had a much better developed hallux which is typically reduced or absent in modern flamingos. History and naming ''Phoenicopterus novaehollandiae'' was named based on a single tarsometatarsus that retains a nearly complete distal end and approximately 95% of the shaft. The bone was discovered in a layer of mudstone that is part of the Etadunna Formation, southeast of Lake Pitikanta within the Lake Eyre basin. Description The general anatomy of the holotype tarsometatarsus resembles that of the modern greater flamingo and American flamingo, being slender and elongated. ''P. novaehollandiae'' however differs significantly in the fact that there is a clear scar on the bone from where the first metatarsus, the first toe, would ...

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 ...

Ligaments
A ligament is the fibrous connective tissue that connects bones to other bones. It is also known as ''articular ligament'', ''articular larua'', ''fibrous ligament'', or ''true ligament''. Other ligaments in the body include the: * Peritoneal ligament: a fold of peritoneum or other membranes. * Fetal remnant ligament: the remnants of a fetal tubular structure. * Periodontal ligament: a group of fibers that attach the cementum of teeth to the surrounding alveolar bone. Ligaments are similar to tendons and fasciae as they are all made of connective tissue. The differences among them are in the connections that they make: ligaments connect one bone to another bone, tendons connect muscle to bone, and fasciae connect muscles to other muscles. These are all found in the skeletal system of the human body. Ligaments cannot usually be regenerated naturally; however, there are periodontal ligament stem cells located near the periodontal ligament which are involved in the adult regener ...

Fossil Taxa Described In 1963
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''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absol ...

Phoeniconotius
''Phoeniconotius'' is an extinct genus of flamingo that lived in Australia from the late Oligocene to the early Miocene. Unlike modern flamingos and the contemporary '' Phoenicopterus novaehollandiae'', it was likely less well adapted for swimming and deep water wading. ''Phoeniconotius'' was a robust flamingo with bones more massive than those of the modern greater flamingo. Only a single species is recognized, ''Phoeniconotius eyrensis''. History The fossils of ''Phoeniconotius'' have been discovered in the Lake Eyre basin of Australia, specifically a layer of mudstone belonging to the Etadunna Formation on the western shore of Lake Palankarinna. The type material consists of three bones, the distal end of the left tarsometatarsus and two phalanges. The material was collected from the surface and were discovered in association with one another, however not articulated. One phalax, which is thought to represent the third toe, matches well with the corresponding area on the ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trochlea
Trochlea (Latin for pulley) is a term in anatomy. It refers to a grooved structure reminiscent of a pulley's wheel. Related to joints Most commonly, trochleae bear the articular surface of saddle joint, saddle and other joints: * Trochlea of humerus (part of the elbow hinge joint with the ulna) * Trochlea of femur (forming the knee hinge joint with the patella) * The trochlea tali in the superior surface of the body of talus (part of the ankle hinge joint with the tibia) * Trochlear process of the calcaneus * In quadrupeds, the trochlea of Radius (bone) * The "knuckles" of the tarsometatarsus which articulate with the proximal phalanges in a bird's foot Related to muscles It also can refer to structures which serve as a guide for muscles: * Trochlea of superior oblique (see also superior oblique muscle), a mover of the eye which is supplied by the trochlear nerve, or fourth cranial nerve {{disambiguation ...

Metatarsus
The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes. Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and fifth metatarsal (often depicted with Roman numerals). The metatarsals are analogous to the metacarpal bones of the hand. The lengths of the metatarsal bones in humans are, in descending order, second, third, fourth, fifth, and first. Structure The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (proximally), and a head (distally).Platzer 2004, p. 220 The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above. The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
