Morganucodon
''Morganucodon'' ("Glamorgan tooth") is an early mammaliaform genus that lived from the Late Triassic to the Middle Jurassic. It first appeared about 205 million years ago. Unlike many other early mammaliaforms, ''Morganucodon'' is well represented by abundant and well preserved (though in the vast majority of cases disarticulated) material. Most of this comes from Glamorgan in Wales (''Morganucodon watsoni''), but fossils have also been found in Yunnan Province in China (''Morganucodon oehleri'') and various parts of Europe and North America. Some closely related animals (''Megazostrodon'') are known from exquisite fossils from South Africa. The name comes from a Latinization of ''Morganuc'', the name for South Glamorgan in the Domesday Book, the county of Wales where it was discovered by Walter Georg Kühne,Walter G. Kühne, "On a Triconodont tooth of a new pattern from a Fissure-filling in South Glamorgan", ''Proceedings of the Zoological Society of London'', volume 119 (1949 ...

Mammaliaform
Mammaliaformes ("mammalian forms") is a clade that contains the crown group mammals and their closest extinct relatives; the group radiated from earlier probainognathian cynodonts. It is defined as the clade originating from the most recent common ancestor of Morganucodonta and the crown group mammals; the latter is the clade originating with the most recent common ancestor of extant Monotremata, Marsupialia, and Placentalia. Besides Morganucodonta and the crown group mammals, Mammaliaformes includes Docodonta and ''Hadrocodium'' as well as the Triassic ''Tikitherium'', the earliest known member of the group. Mammaliaformes is a term of phylogenetic nomenclature. In contrast, the assignment of organisms to Mammalia has traditionally been founded on traits and, on this basis, Mammalia is slightly more inclusive than Mammaliaformes. In particular, trait-based taxonomy generally includes '' Adelobasileus'' and '' Sinoconodon'' in Mammalia, though they fall outside the Mammaliaforme ...

Eozostrodon
''Eozostrodon'' is an extinct morganucodont mammaliaform. It lived during the Rhaetian stage of the Late Triassic. ''Eozostrodon'' is known from disarticulated bones from Wales and South West England and estimated to have been less than in head-body length, slightly smaller than the similar-proportioned ''Megazostrodon''. ''Eozostrodon'' was described on the basis of two teeth discovered in a quarry near Frome in Somerset, England, each originally assigned to separate species ''E. parvus'' and ''E. problematicus''. The latter was synonymized in 1971. The identity of and status of ''Eozostrodon'' is controversial. Kühne considered ''Eozostrodon'' to be "one and the same" with ''Morganucodon'' which he described, albeit after the published description of ''Eozostrodon'', claiming "...for a number of good reasons ''Morganucodon'' ought to be used, the name of ''Eozostrodon'' being used for sentimental reasons only or because of ignorance." Jenkins and Crompton in 1979 argued ''Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kenneth Kermack
Kenneth A. Kermack (1919 – 2000) was a British palaeontologist at University College London most notable for his work on early mammals with his wife, Doris Mary Kermack. Among Kermack's other significant contributions was the observation that ''Diplodocus ''Diplodocus'' (, , or ) was a genus of diplodocid sauropod dinosaurs, whose fossils were first discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a neo-Latin term derived from Greek δ ...'' could not have had an aquatic lifestyle because sheer water pressure alone on its chest would have prevented it breathing whilst submerged. He first described the early mammal ''Aegialodon dawsoni'' from a molar tooth and the docodont ''Simpsonodon oxfordensis''. He was also interested in astronomy, elected a member of the British Astronomical Association 1966 February 23, a member until his death. Selected publications * Kermack, D. M., Kermack, K.

Walter Georg Kühne
Walter Georg Kühne (February 26, 1911 in Berlin – March 16, 1991 ibid.) was a German paleontologist, known as a "legendary explorer of Mesozoic mammals". He graduated in March 1930 from reform boarding school ''Schule am Meer'' on the island of Juist in Prussia. In 1958 he founded the Institute for Paleontology of the Free University of Berlin. His studies focused specifically on mesozoic microfauna, seeking to bring to light the history of the oldest mammals, which until the 1960s was almost unknown. Before him, findings of species of small size in the continental Mesozoic deposits had been mostly random. His efforts were concentrated more in excavations in lignite mines which he considered as preferred deposits for the remains of terrestrial vertebrates. Thanks to his efforts new species could be described that were interpreted as the most primitive mammals as Morganucodon and Kuehneotherium, as well the proto-mammal Oligokyphus ''Oligokyphus'' ("few cusps") is an extinct g ...

Bernhard Peyer
Bernhard Peyer (25 July 1885 – 23 February 1963) was a Swiss paleontologist and anatomist who served as a professor at the University of Zurich. A major contribution was on the evolution of vertebrate teeth. Peyer was born in Schaffhausen, Switzerland, the son of a textile-factory owning namesake father and Sophie Frey. While at secondary school in Schaffhausen he met Ferdinand Schalch in the field who influenced him into paleontology although there had been scientists in the family in the past, including the anatomist Johann Conrad Peyer (1653-1712). In 1905 he went to study at the University of Tübingen and then at Munich where he listed to lectures by Richard von Hertwig, Ferdinand Broili and Ernst Stromer von Reichenbach. In 1907 he graduated from the University of Zurich with a dissertation on ''Die Entwicklung des Schädelskeletes von Vipera aspis'' under Arnold Lang. He received a doctorate in 1911. In 1912 he went on an expedition to Rovigno, Italy and then to South Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch of the Triassic Period in the geologic time scale, spanning the time between Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and '' Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', the middle Muschelkalk (shell-bearing limestone) and the upper Keuper (coloured clay).

Hallau
Hallau is a municipality in the canton of Schaffhausen in Switzerland. History Though Bronze Age weapons have been found in Hallau, the first traces of a settlement date from the Roman era. A Roman warehouse was found in Hüttenhau as well as numerous Roman coins. The area was settled by the Alamanni. An Alamanni graveyard exists near the Church of St. Moritz, as well as the ruins of the Alamanni village of Atlingen. Hallau is first mentioned in 1095 as ''Hallaugia superiori et inferiori''. In 1273 it was mentioned as ''Hallowe''. Until 1526 it was part of Oberhallau. About two-thirds of the land in Hallau was originally owned by the Benedictine monastery of All Saints in Schaffhausen. In the tax record from 1100, there are no vineyards mentioned in the villages. It is not until the ''Kelhofbrief'' of 1280 that the local vineyards first appear. In 1302 the Bishop of Konstanz acquired the vogtei rights over both villages. In 1343 the village organized the ''Gebursami ze ...
