Sophineta
''Sophineta'' is an extinct genus of basal lepidosauromorph reptile known from the Early Triassic (late Olenekian age) of Małopolska Province, southern Poland. It contains a single species, ''Sophineta cracoviensis''. Discovery ''Sophineta'' was first described and named by Susan E. Evans and Magdalena Borsuk−Białynicka in 2009, and the type species is ''Sophineta cracoviensis''. It is known from holotype ZPAL RV/175, a nearly complete right maxilla. Many isolated or associated skull and postcranial fragments are referred to the species, representing frontals, parietals, prefrontal, postfrontals, postorbitals, jugals, squamosals, pterygoids, quadrates, maxillae, premaxilla, dentaries, vertebrae and ilia. ''Sophineta'' fossils were discovered ''in situ'' and collected in 1982 by a team (Paszkowski and Wieczorek) from the Institute of Geological Sciences of Jagiellonian University in Kraków. They were collected from the Czatkowice 1 locality, a single exposure near Kr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidosauromorph
Lepidosauromorpha (in PhyloCode known as ''Pan-Lepidosauria'') is a group of reptiles comprising all diapsids closer to lizards than to archosaurs (which include crocodiles and birds). The only living sub-group is the Lepidosauria, which contains two subdivisions, Squamata, which contains lizards and snakes, and Rhynchocephalia, the only extant species of which is the tuatara. Lepidosauromorphs are distinguishable from archosauromorphs (reptiles closer to archosaurs) by their primitive sprawling gait (allowing for the same sinusoidal trunk and tail movement seen in fish), the sliding "joint" between the coracoids and the sternum (for a longer stride), and their pleurodont dentition. In contrast, Archosauromorphs possess a parasagittal gait, a reduction in their dermal girdle, a reduction and/or loss of the sternum, and a more thecodont dentition. Living lepidosauromorphs have retained an ectothermic (" cold blooded") metabolism, unlike the ancestral condition in archosauromorphs. ...

Marmoretta
''Marmoretta'' is an extinct genus of small lepidosauromorph reptile known from the Middle Jurassic (late Bathonian age) of Oxfordshire, England and Skye, Scotland. It contains a single species, ''Marmoretta oxoniensis''. Etymology ''Marmoretta'' was first described and named by Susan E. Evans in 1991 and the type species is ''Marmoretta oxoniensis''. The generic name is derived from Latin ''marmoros'', meaning "Marble" and refers to the Forest Marble Formation - the source of the initial specimens of ''Marmoretta''. The specific name is derived from ''Oxonia'', the Latinised form of "Oxford", in reference to Oxfordshire. Discovery ''Marmoretta'' is known from holotype BMNH R.12020, the anterior region of a right maxilla. Many specimens are referred to the species from the type locality, and together represent a nearly complete skull. All specimens are housed in the Natural History Museum. They were collected from the Mammal Bed of the Forest Marble Formation, at Kirtlin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuehneosaur
Kuehneosauridae is an extinct family of small, lizard-like gliding diapsids known from the Triassic period of Europe and North America. They are distinguished from other diapsids by their 'wings' formed by elongated ribs. These allowed the animal to glide and parachute similar to living gliding lizards. They were most likely insectivorous, judging from their pin-like teeth. They are often, but not always, placed in the group Lepidosauromorpha, though other studies have recovered them in other positions within Sauria, including Archosauromorpha. The oldest and most primitive known member is ''Pamelina'' from the Early Triassic (Olenekian stage) of Poland, which already has vertebrae with characteristics consistent with gliding or parachuting. ''Icarosaurus'' is known from a single specimen from the Carnian-aged Lockatong Formation of New Jersey. The Late Triassic (Norian stage) kuehneosaurids from England, ''Kuehneosaurus'' and ''Kuehneosuchus'', are very similar and can be disting ...

2009 In Paleontology
Arthropods Cephalopods Three new species of extinct octopus, Octopoda discovered in 2009. The species – ''Keuppia hyperbolaris'', ''Keuppia levante'', and ''Styletoctopus annae'' – lived about 95 million years ago, and bear a strong resemblance to modern octopuses, suggesting that the Octopoda order has remained relatively unchanged for tens of millions of years. The fossils included evidence of cephalopod arm, arms, muscles, rows of suckers, cephalopod ink, ink, and internal gills. The discovery was made by a team led by Dirk Fuchs of the Freie University, which is located at Berlin, Germany.Rare fossil octopuses found NBC News, March 18, 2009 The fossils were found at Hakel and Hadjoula, Lebanon.

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the in ...

Geological Timescale
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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 Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zofia Kielan-Jaworowska
Zofia Kielan-Jaworowska (25 April 1925 – 13 March 2015) was a Polish paleobiologist. In the mid-1960s, she led a series of Polish-Mongolian paleontological expeditions to the Gobi Desert. She was the first woman to serve on the executive committee of the International Union of Geological Sciences. Early life and education Zofia Kielan-Jaworowska was born in Sokołów Podlaski, Poland, on April 25, 1925. In 1928, her father, Franciszek Kielan, was offered a job for the Association of Agriculture and Trade Cooperatives in Warsaw, to which her family moved for five years. Zofia and family returned to Warsaw in 1934 and lived in Żoliborz - a borough of Warsaw. She began her studies in Warsaw, following the destruction after the war when the Nazis had attempted to completely destroy the city, resulting in the Department of Geology joining the ruins. She attended lectures given instead by the Polish paleontologist, Roman Kozłowski, in his own home. This is her where her passion b ...

Name Of A Biological Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstr ...
