Arminisaurus Schuberti Scapula
''Arminisaurus'' (meaning "lizard of Arminius") is a genus of pliosaurid plesiosaur that lived during the Lower Jurassic in present-day Germany. With ''Westphaliasaurus'' and ''Cryonectes'', ''Arminisaurus'' is only the third plesiosaurian taxon that was described from the Pliensbachian stage. The holotype and only known specimen is a fragmentary skeleton (about 40 percent complete), comprising an incomplete lower jaw, teeth, vertebrae and elements from the pectoral girdle and the paddles. The animal had an estimated body length of . Discovery and naming The holotype was discovered in the early 1980s by the Hannover-based fossil collector Lothar Schulz in the now abandoned clay pit Beukenhorst II, located in the Bielefeld district of Jöllenbeck. The specimen was later given to amateur palaeontologist Siegfried Schubert who transferred it to the Naturkunde-Museum Bielefeld in 2015 (Accession number (library science), accession number: NAMU ES/jl 36052).

Early Jurassic
The Early Jurassic Epoch (in chronostratigraphy corresponding to the Lower Jurassic Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called "Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from South Wales was used throughout North Devon/North Cornwall as it conta ...

Bielefeld
Bielefeld () is a city in the Ostwestfalen-Lippe Region in the north-east of North Rhine-Westphalia, Germany. With a population of 341,755, it is also the most populous city in the administrative region ('' Regierungsbezirk'') of Detmold and the 18th largest city in Germany. The historical centre of the city is situated north of the Teutoburg Forest line of hills, but modern Bielefeld also incorporates boroughs on the opposite side and on the hills. The city is situated on the ', a hiking trail which runs for 156 km along the length of the Teutoburg Forest. Bielefeld is home to a significant number of internationally operating companies, including Dr. Oetker, Gildemeister and Schüco. It has a university and several technical colleges (''Fachhochschulen''). Bielefeld is also famous for the Bethel Institution, and for the Bielefeld conspiracy, which satirises conspiracy theories by claiming that Bielefeld does not exist. This concept has been used in the town's m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptocleidia
Leptocleidia is a clade of plesiosauroids. The group was erected in 2007 as Leptocleidoidea. Although established as a clade, the name Leptocleidoidea implies that it is a superfamily. Leptocleidoidea is placed within the superfamily Plesiosauroidea, so it was renamed Leptocleidia by Hilary F. Ketchum and Roger B. J. Benson (2010) to avoid confusion with ranks. Leptocleidia is a node-based taxon which was defined by Ketchum and Benson as "'' Leptocleidus superstes'', ''Polycotylus latipinnis ''Polycotylus'' is a genus of plesiosaur within the family Polycotylidae. The type species is ''P. latippinis'' and was named by American paleontologist Edward Drinker Cope in 1869. Eleven other species have been identified. The name means 'muc ...'', their most recent common ancestor and all of its descendants". References Plesiosaurs Fossil taxa described in 2010 {{plesiosaur-stub ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

Pliosaur
Pliosauroidea is an extinct clade of plesiosaurs, known from the earliest Jurassic to early Late Cretaceous. They are best known for the subclade Thalassophonea, which contained crocodile-like short-necked forms with large heads and massive toothed jaws, commonly known as pliosaurs. More primitive non-thalassophonean pliosauroids resembled pleisiosaurs in possessing relatively long necks and smaller heads. They originally included only members of the family Pliosauridae, of the order Plesiosauria, but several other genera and families are now also included, the number and details of which vary according to the classification used. The distinguishing characteristics are a short neck and an elongated head, with larger hind flippers compared to the fore flippers, the opposite of the plesiosaurs. They were carnivorous and their long and powerful jaws carried many sharp, conical teeth. Pliosaurs range from 4 to 15 metres and more in length. Their prey may have included fish, shar ...

Pliosauridae
Pliosauridae is a family of plesiosaurian marine reptiles from the Latest Triassic to the early Late Cretaceous (Rhaetian to Turonian stages) of Australia, Europe, North America and South America. The family is more inclusive than the archetypal short-necked large headed species that are placed in the subclade Thalassophonea, with basal forms resembling other plesiosaurs with long necks. They became extinct during the early Late Cretaceous and were subsequently replaced by the mosasaurs. It was formally named by Harry G. Seeley in 1874. Relationships Pliosauridae is a stem-based taxon defined in 2010 (and in earlier studies in a similar manner) as "all taxa more closely related to '' Pliosaurus brachydeirus'' than to ''Leptocleidus superstes'', ''Polycotylus latipinnis'' or '' Meyerasaurus victor''". The family Brachauchenidae has been proposed to include pliosauroids which have very short necks and may include '' Brachauchenius'' and '' Kronosaurus''. However, modern clad ...

Battle Of The Teutoburg Forest
The Battle of the Teutoburg Forest, described as the Varian Disaster () by Roman historians, took place at modern Kalkriese in AD 9, when an alliance of Germanic peoples ambushed Roman legions and their auxiliaries, led by Publius Quinctilius Varus. The alliance was led by Arminius, a Germanic officer of Varus's auxilia. Arminius had acquired Roman citizenship and had received a Roman military education, which enabled him to deceive the Roman commander methodically and anticipate the Roman army's tactical responses. Teutoburg Forest is commonly seen as one of the most important defeats in Roman history, bringing the triumphant period of expansion under Augustus to an abrupt end. The outcome of this battle dissuaded the Romans from their ambition of conquering Germania, and is thus considered one of the most important events in European history. The provinces of Germania Superior and Germania Inferior, sometimes collectively referred to as ''Roman Germania'', were subsequ ...

Roman Legion
The Roman legion ( la, legiō, ) was the largest military unit of the Roman army, composed of 5,200 infantry and 300 equites (cavalry) in the period of the Roman Republic (509 BC–27 BC) and of 5,600 infantry and 200 auxilia in the period of the Roman Empire (27 BC – AD 476). Size The size of a typical legion varied throughout the history of ancient Rome, with complements ranging from 4,200 legionaries and 300 equites (drawn from the wealthier classes – in early Rome all troops provided their own equipment) in the Republican period of Rome (the infantry were split into 10 Cohort (military unit), cohorts each of four Maniple (military unit), maniples of 120 legionaries), to 4,800 legionaries (in 10 cohorts of 6 centuries of 80 legionaries) during Caesar's age, to 5,280 men plus 120 auxiliaries in the Imperial period (split into 10 cohorts, nine of 480 men each, with the first cohort being double-strength at 960 men).

Tribe
The term tribe is used in many different contexts to refer to a category of human social group. The predominant worldwide usage of the term in English is in the discipline of anthropology. This definition is contested, in part due to conflicting theoretical understandings of social and kinship structures, and also reflecting the problematic application of this concept to extremely diverse human societies. The concept is often contrasted by anthropologists with other social and kinship groups, being hierarchically larger than a lineage or clan, but smaller than a chiefdom, nation or state. These terms are equally disputed. In some cases tribes have legal recognition and some degree of political autonomy from national or federal government, but this legalistic usage of the term may conflict with anthropological definitions. In the United States, Native American tribes are legally considered to have "domestic dependent nation" status within the territorial United States, ...

Cherusci
The Cherusci were a Germanic tribe that inhabited parts of the plains and forests of northwestern Germany in the area of the Weser River and present-day Hanover during the first centuries BC and AD. Roman sources reported they considered themselves kin with other Irmino tribes and claimed common descent from an ancestor called Mannus. During the early Roman Empire under Augustus, the Cherusci first served as allies of Rome and sent sons of their chieftains to receive Roman education and serve in the Roman army as auxiliaries. The Cherusci leader Arminius led a confederation of tribes in the ambush that destroyed three Roman legions in the Teutoburg Forest in AD9. He was subsequently kept from further damaging Rome by disputes with the Marcomanni and reprisal attacks led by Germanicus. After rebel Cherusci killed Arminius in AD21, infighting among the royal family led to the highly Romanized line of his brother Flavus coming to power. Following their defeat by the Chatti ...
