Pachydyptes Ponderosus
''Pachydyptes'' is an extinct genus of penguin. It contains the single species ''Pachydyptes ponderosus'', the New Zealand giant penguin. This taxon is known from a few bones from Late Eocene (37 to 34 MYA) rocks in the area of Otago, which were found in two clades near a base of a tree (Ksepka et al., 2006). G.G. Simpson, an evolutionary biologist, estimated a height of 140 to 160 cm (about 5 ft) and a weight of around 80 to possibly over 100 kg (Stonehouse, 1975). it was the second-tallest penguin ever, surpassed only by ''Anthropornis nordenskjoeldi'' in height, but probably not in weight. This was because of the clade's evolutionary history, where many early penguins were typically found larger in size (Ksepka et al., 2006). G.G. Simpson had also claimed from the fossil records that the Pachydyptes along with many other early penguin species, descended from flying ancestors (Stonehouse, 1975). ''Pachydyptes'' was slightly larger than ''Icadyptes salasi ' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Late Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Students Find Fossilised Giant Penguin
A student is a person enrolled in a school or other educational institution. In the United Kingdom and most commonwealth countries, a "student" attends a secondary school or higher (e.g., college or university); those in primary or elementary schools are "pupils". Africa Nigeria In Nigeria, education is classified into four system known as a 6-3-3-4 system of education. It implies six years in primary school, three years in junior secondary, three years in senior secondary and four years in the university. However, the number of years to be spent in university is mostly determined by the course of study. Some courses have longer study length than others. Those in primary school are often referred to as pupils. Those in university, as well as those in secondary school, are referred to as students. The Nigerian system of education also has other recognized categories like the polytechnics and colleges of education. The Polytechnic gives out National Diploma and Higher Nation ...

Fossils Of New Zealand
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 ...

Extinct Penguins
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, mam ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Palaeeudyptinae
Palaeeudyptinae, the giant penguins, is a paraphyletic subfamily of prehistoric penguins. It includes several genera of medium-sized to very large species, such as ''Icadyptes salasi'', '' Palaeeudyptes marplesi'', ''Anthropornis nordenskjoeldi'', and '' Pachydyptes ponderosus''. ''Icadyptes'' reached in height, while members of ''Palaeeudyptes'' and ''Anthropornis'' grew even taller and were some of the largest penguins to have ever existed. The massive ''P. ponderosus'' may have weighed at least as much as an adult human. Lineage They belonged to an evolutionary lineage more primitive than modern penguins. In some taxa at least, the wing, while already having lost the avian feathering, had not yet transformed into the semi-rigid flipper found in modern penguin species: While the ulna and the radius were already flattened to increase propelling capacity, the elbow and wrist joints still retained a higher degree of flexibility than the more rigidly lockable structure found in moder ...

Icadyptes Salasi
''Icadyptes'' is an extinct genus of giant penguins from the Late Eocene tropics of South America. Etymology The genus name is a combination of "''Ica''" for the Peruvian region where the type species was found and "dyptes" from the Greek word for diver. The species epithet "salasi" refers to Rodolfo Salas Gismondi, a noted Peruvian paleontologist. Description Standing about tall, the penguin was much larger than any of its modern-day cousins, yet ''Icadyptes salasi'' is merely the third largest penguin ever described. It had an exceptionally long spear-like beak resembling that of a heron. The researchers who discovered the penguins believe the long, pointed beaks to be the likely ancestral shape for all penguins. Discovery The fossilised remains of the penguin, which lived approximately 36 million years ago, were found in the Otuma Formation, [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Walter Oliver
Walter Reginald Brook Oliver (7 September 1883 – 16 May 1957) was a New Zealand naturalist, ornithologist, malacologist, and museum curator. Biography Born in Launceston, Tasmania, Oliver emigrated with his family to New Zealand in 1896, settling in Tauranga. Having already developed an interest in nature during his childhood, he systematically recorded natural observations throughout much of his life, joining other naturalists on an expedition to the Kermadec Islands in 1908. In 1910, Oliver became a member of the Royal Australasian Ornithologists Union (RAOU) for which body he served as branch secretary for New Zealand from 1914 to his death in 1957, a period of office of 43 years. During this period, he also served as RAOU vice-president from 1942 to 1943, and as president from 1943 to 1944. Oliver was appointed director of the Dominion Museum in 1928, and in 1930, he published the seminal guide ''New Zealand Birds'', which was updated and expanded in 1955. The guide cont ...

Anthropornis Nordenskjoeldi
''Anthropornis'' is a genus of giant penguin that lived 45-33 million years ago, during the Late Eocene and the earliest part of the Oligocene.Myrcha, A., Jadwiszczak, P., Tambussi, C.P., Noriega, J.I., Gazdzicki, A., Tatur, A., and Valle, R.A. (2002). "Taxonomic Revision of Eocene Antarctic Penguins Based on Tarsometatarsal Morphology". ''Polish Polar Research'', 23(1): 5-46 Description ''Anthropornis'' reached in length from the tip of the beak to the tip of the tail, and in weight. There is also an estimate that one remain of ''Anthropornis'' can reach that body length of and in weight. Fossils of it have been found in the La Meseta Formation on Seymour Island off the coast of Antarctica and in New Zealand. By comparison, the largest modern penguin species, the emperor penguin, is just long. The type species, ''Anthropornis nordenskjoldi'', had a bent joint in the wing, probably a vestigial Vestigiality is the retention, during the process of evolution, of gen ...

Otago
Otago (, ; mi, Ōtākou ) is a region of New Zealand located in the southern half of the South Island administered by the Otago Regional Council. It has an area of approximately , making it the country's second largest local government region. Its population was The name "Otago" is the local southern Māori dialect pronunciation of "Ōtākou", the name of the Māori village near the entrance to Otago Harbour. The exact meaning of the term is disputed, with common translations being "isolated village" and "place of red earth", the latter referring to the reddish-ochre clay which is common in the area around Dunedin. "Otago" is also the old name of the European settlement on the harbour, established by the Weller Brothers in 1831, which lies close to Otakou. The upper harbour later became the focus of the Otago Association, an offshoot of the Free Church of Scotland, notable for its adoption of the principle that ordinary people, not the landowner, should choose the ministe ...
