Dichodon (mammal)
''Dichodon'' is an extinct genus of Palaeogene artiodactyls belonging to the family Xiphodontidae. It was endemic to western Europe and lived from the middle Eocene up to the earliest Oligocene. The genus was first erected by the British naturalist Richard Owen in 1848 based on dental remains from the fossil beds in Hordle, England. He noticed similar dentitions to contemporary artiodactyls like those of the Anoplotheriidae and Dichobunidae and based the genus name off of ''Dichobune''. Eventually, it was found to be more closely related to ''Xiphodon'' and now composes of 11 species, although one of them may be synonymous. The xiphodontid had brachyodont (low-crowned) dentition, its premolars being elongated similar to other xiphodonts. However, it differs from them by the "molarization" of the fourth premolars, meaning that the top teeth appear quadrangular while the bottom ones appear more triangular. Its snout is also shorter and narrower compared to that of ''Xiphodon''. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frohnstetten
Stetten am kalten Markt (Stetten a.k.M.) is a municipality in the Sigmaringen district of Baden-Württemberg, Germany. Towns The towns of Nusplingen, Frohnstetten, Storzingen and Glashütte are part of Stetten am kalten Markt. History The area was documented early as being in the possession of the Reichenau monastery as "Stetten am kalten Markt." Within the Heuberg Training Area there is the legendary ''Dreibannmarke'', also called the "Bahn", a 17th-century border, which today marks the border between three different municipalities, formerly in the three states of Württemberg, Baden, and Hohenzollern. The meadow at the Dreibannmarke served as a stopping place for traveling merchants, wagons and craftsmen. With care it is possible to identify traces of the border. After the inauguration of the firing ranges, a meadow in Meßstetten was allocated as a camping site at the edge of the restricted area. Until 1835 merchandise was smuggled over the customs borders guarded by local hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Georg Bronn
Heinrich Georg Bronn (3 March 1800 – 5 July 1862) was a German geologist and paleontologist. He was the first to translate Charles Darwin's ''On the Origin of Species'' into German in 1860, although not without introducing his own interpretations, as also a chapter critiquing the work. Bibliography Bronn was born at Ziegelhausen (now part of Heidelberg) in the electoral Palatinate. Studying at the university of Heidelberg he took his doctor's degree in the faculty of medicine in 1821, and in the following year was appointed professor of natural history. He now devoted himself to palaeontological studies, and to field-work in various parts of Germany, Italy and France. From its commencement in 1830 to 1862 he assisted in editing the ''Jahrbuch für Mineralogie'' continued as ''Neues Jahrbuch''. His principal work, ''Letkaea Geognostica'' (2 vols., Stuttgart, 1834–1838; 3rd ed. with F. Romer, 3 vols., 1851–1856), has been regarded as one of the foundations of German strati ...

Christian Erich Hermann Von Meyer
Christian Erich Hermann von Meyer (3 September 1801 – 2 April 1869), known as Hermann von Meyer, was a German palaeontologist. He was awarded the 1858 Wollaston medal by the Geological Society of London. Life He was born at Frankfurt am Main. In 1832, Meyer issued a work entitled ''Palaeologica'', and in course of time he published a series of memoirs on various fossil organic remains: molluscs, crustaceans, fishes and higher vertebrata, including the Triassic predator '' Teratosaurus'', the earliest bird '' Archaeopteryx lithographica'' (1861), the pterosaur ''Rhamphorhynchus'', and the prosauropod dinosaur '' Plateosaurus''. In ''Palaeologica'', Meyer proposed a classification of fossil reptiles into four major groups based on their limbs: *Saurians with Toes Similar to those of Living Species (e.g.'' Teleosaurus'', '' Protorosaurus'', ''Streptospondylus'') *Saurians with Limbs Similar to Heavy Land Mammals ('' Iguanodon'', '' Megalosaurus'') *Saurians with Limbs fo ...

Alum Bay
Alum Bay is a bay near the westernmost point of the Isle of Wight, England, within close sight of the Needles rock formation. Of geological interest and a tourist attraction, the bay is noted for its multi-coloured sand cliffs. The waters and adjoining seabed form part of the Needles Marine Conservation Zone and the shore and heath above are part of the Headon Warren and West High Down Site of Special Scientific Interest. Geology Alum Bay is the location of a classic sequence of upper Paleocene and Eocene beds of soft sands and clays, separated by an unconformity from the underlying Cretaceous Chalk Formation that forms the adjoining headland of West High Down. Due to geological folding of the Alpine orogeny, the strata in the main section of the bay are near vertical, with younger rocks with progressively lower dips to the west. The sands are coloured due to oxidised iron compounds formed under different conditions. Alum Bay Chine begins as a small wooded valley descendin ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anoplotheriid
Anoplotheriidae is an extinct family of even-toed ungulates (order Artiodactyla). They were endemic to Western Europe during the Eocene and Oligocene epochs about 48—23 million years ago (Mya), existing for about 25 million years. They disappeared at the end of the Oligocene, leaving no survivors today. Its name is derived from the grc, ἂνοπλος ("unarmed") and θήριον ("beast"), translating as "unarmed beast". They were most likely mid-sized terrestrial herbivores not too distantly related to camels, but smaller and low-slung with long and thick tails, and rather generalistic. The climate during their time was warmer than today, and their habitats were probably subtropical or even tropical, with plentiful rainfall and abundant vegetation. Tropical rainforest may at least initially have occurred all over the Anoplotheriidae's range. Ecologically, they may have resembled a large duiker of our time (e.g. the similarly sized yellow-backed duiker ''Cephalophus ...

They are used primarily to comminution, grind food during mastication, chewing. The name ''molar'' derives from Latin, ''molaris dens'', meaning "millstone tooth", from ''mola'', millstone and ''dens'', tooth. Molars show a great deal of diversity in size and shape across mammal groups. The third molar of humans is sometimes vestigial. Human anatomy In humans, the molar teeth have either four or five cusp (dentistry), cusps. Adult humans have 12 molars, in four groups of three at the back of the mouth.

Merycopotamus
''Merycopotamus'' is an extinct genus of Asian anthracothere that appeared during the Middle Miocene The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million y ..., and died out in the Late Pliocene. At the height of the genus' influence, species ranged throughout southern Asia. With the extinction of the last species, ''M. dissimilis'', the lineage of anthracotheres came to an end. ''Merycopotamus'' was closely related to the anthracothere genus '' Libycosaurus'', which, unlike the former, never left Africa. In fact, some African fossils originally placed in ''Merycopotamus'', but are now referred to ''Libycosaurus''.
