Johann August Georg Edmund Mojsisovics Von Mojsvar
Johann August Georg Edmund Mojsisovics von Mojsvár (18 October 18392 October 1907) was an Austro-Hungarian geologist and palaeontologist. Biography Mojsisovics was the son of the surgeon Georg Mojsisovics von Mojsvar (1799–1860). His name in Hungarian: Ödön. He was born in Vienna. He studied law in Vienna University, taking his doctorate degree in 1864, and in 1867 he entered the Geological Institute, becoming chief geologist in 1870 and vice-director in 1892. He retired in 1900 and died at Mallnitz on 2 October 1907. Works Mojsvar paid special attention to the Cephalopoda of the Austrian Triassic, and his publications include: * ''Das Gebirge um Hallstatt'' (1873, 1876). * ''Die Dolomit-Riffe von Südtirol und Venetien'' (1878–1880). * ''Grundlinien der Geologie von Bosnien-Herzegowina'' (1880), with Emil Tietze and Alexander Bittner. * ''Die Cephalopoden der mediterranen Triasprovinz'' (1882). * ''Die cephalopoden der Hallstätter Kalke'' (1873, 1902). * ''Beiträge ...

Ceratites
''Ceratites'' is an extinct genus of ammonite cephalopods. These nektonic carnivores lived in marine habitats in what is now Europe, during the Triassic, from the upper-most Anisian to the lower Ladinian age.Sepkoski, JacSepkoski's Online Genus Database – Cephalopoda/ref> Description This ammonite has a ceratitic suture pattern on its shell (smooth lobes and frilly saddles). Evolution of the frilly saddles is thought to be due to increased pressure on the shell, at greater depth. The frilly pattern would increase the strength of the shell and allow ''Ceratites'' to dive deeper, possibly in search of food. Distribution Fossils of this genus are only known from the Germanic Basin, which formed a partially isolated shallow sea across much of Europe from eastern France north of the future Alps and into Poland, separated from the Tethys by 3 gates that variably opened. The salinity of the water in this partially isolated basin may have been one of the main factors keeping ammonoid a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Perrin Smith
James Perrin Smith (November 27, 1864 – January 1, 1931) was an American geologist and paleontologist. Smith was of English descent. T. M. Forster, one of his ancestors, was a surgeon in the Royal Navy and moved to Virginia in 1745. His paternal grandfather moved the family from Virginia to South Carolina, and Smith was born on November 27, 1864, near Cokesburg, to James Francis Smith, a planter and traveling preacher. James P. Smith was educated by his parents and elder brother Charles Forster Smith. In the 1870s, the family moved to Spartanburg, South Carolina, where James obtained a bachelor's degree at Wofford College in 1884. Smith then attended Vanderbilt University until 1887, for a master's degree. He subsequently taught high school science and mathematics in Nashville, Tennessee for two years. Smith then worked for the Arkansas Geological Survey under John Casper Branner. Between 1890 and 1892, Smith studied at the University of Göttingen. His doctoral work was supervise ...

Ammonoidea
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder ( 79 AD nea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalopod
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ident ...

Triassic Cephalopods
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago (Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archosaurs, ...

Fossils Of China
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 absolute ...

Fauna Of Israel
The wildlife of Israel includes the flora and fauna of Israel, which is extremely diverse due to the country's location between the temperate and the tropical zones, bordering the Mediterranean Sea in the west and the desert in the east. Species such as the Syrian brown bear and the Arabian ostrich have become extinct in Israel because of their loss of habitat. As of May 2007, 190 nature reserves have been established in Israel. Fauna Mammals Israel contains a variety of mammals due to its geographical and climatic diversity. For many of the mammals, Israel is the border of their territory. The territories of species which originate in the Palearctic generally stop at the deserts and those who originate from the African deserts usually stop at the Mediterranean coasts. Most of the mammals in Israel are of a Palearctic origin and about a tenth of the mammals are endemic to its general area. The Land of Israel once contained a variety of mammals, however in recent times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
