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 ( ...

Denise Sigogneau-Russell
Denise Sigogneau-Russell (born ''c.'' 1941/42) is a French palaeontologist who specialises in mammals from the Mesozoic, particularly from France and the UK. She is currently based at the Muséum National d'Histoire Naturelle. Background Denise Sigogneau-Russell completed her PhD in 1969 on therapsids - the forerunners of mammals - from South Africa, where she spent two years. In 1976 a Belgian amateur fossil hunter brought her a mammal tooth from a quarry in eastern France, and this inspired her to change direction and begin research on mammals from the Mesozoic.Kielan-Jaworowska, Z. 2013. ''In Pursuit of Early Mammals''. Indiana University Press. She subsequently studied them in France, Portugal, Madagascar, Morocco, and England. Zofia Kielan-Jaworowska said that due to Sigogneau-Russell's "scholarship and diligence, she has contributed enormously to the knowledge of early mammal evolution.". She was married to Donald E. Russell, also a palaeontologist specialising in mammals, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Mamm ...

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 ''Mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, 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 August von Namoh, 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'')'', t ...

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 Doris Mary Kermack FLS (née Carr; 1923 – 2003) was a British paleontologist and marine zoologist at Imperial College London. She completed her PhD thesis entitled 'The anatomy and physiology of the gut of ''Arenicola marina'' L.' at Unive .... Among Kermack's other significant contributions was the observation that '' Diplodocus'' 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.

Dorset
Dorset ( ; archaically: Dorsetshire , ) is a county in South West England on the English Channel coast. The ceremonial county comprises the unitary authority areas of Bournemouth, Christchurch and Poole and Dorset. Covering an area of , Dorset borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The county town is Dorchester, in the south. After the reorganisation of local government in 1974, the county border was extended eastward to incorporate the Hampshire towns of Bournemouth and Christchurch. Around half of the population lives in the South East Dorset conurbation, while the rest of the county is largely rural with a low population density. The county has a long history of human settlement stretching back to the Neolithic era. The Romans conquered Dorset's indigenous Celtic tribe, and during the Early Middle Ages, the Saxons settled the area and made Dorset a shire in the 7th century. The first re ...

Eype
Eype ( ) is a small village in southwest Dorset, England, situated southwest of Bridport. It lies on the Jurassic Coast World Heritage Site on the English Channel and is within the civil parish of Symondsbury. Eype means "steep place". Many of the village buildings can be traced back to the late eighteenth or early nineteenth centuries, but little is known in detail until the Victorian era.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rhaetian
The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy). It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic). The base of the Rhaetian lacks a formal GSSP, though candidate sections include Steinbergkogel in Austria (since 2007) and Pignola-Abriola in Italy (since 2016). The end of the Rhaetian (and the base of the overlying Hettangian Stage) is more well-defined. According to the current ICS (International Commission on Stratigraphy) system, the Rhaetian ended ± 0.2 Ma ( million years ago). In 2010, the base of the Rhaetian (i.e. the Norian-Rhaetian boundary) was voted to be defined based on the first appearance of '' Misikella posthernsteini'', a marine conodont. However, there is still much debate over the age of this boundary, as well as the evolution of ''M. posthernsteini''. The most comprehensive source of precise ...
