Archaeidae
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and fat. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand. Assassin spiders were first known from 40 million year old amber fossils which were found in Europe in the 1840s, and were not known to have living varieties until 1881, when the first living assassin spider was found in Madagascar. The fossil record of this family was first identified from Baltic amber dating to the Eocene, although many taxa from these deposits have been reassigned to Mecysmaucheniidae, Malka ...

Archaea Levigata
''Archaea'' is an extinct genus of spiders in the family Archaeidae. , four species are placed (or possibly placed) in the genus. All have been found preserved in amber, either from the Baltic or Bitterfeld, Germany. First described in 1854, ''Archaea'' species have a distinctive "neck" separating the head from the thorax, and very long chelicerae ("jaws"). Description In the genus ''Archaea'', the head is separated from the thorax by a deep fold, forming a "neck", so that the globular head appears to sit on the thorax. There are eight eyes, four on each side of the head, arranged in the shape of a rhombus, with the front eyes being the largest. The curved chelicerae are very long, longer than the head, with long, strong fangs. The pedipalps of the female are very small and thin, shorter than the chelicerae, the third and last segments being short, the latter needle-shaped. Those of the male are sturdier, the third segment being almost as long as the second, with the end segment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burmesarchaea Grimaldii
''Burmesarchaea'' is a diverse extinct genus of spiders, placed in the family Archaeidae. The type species ''Burmesarchaea grimaldii'' was first described in 2003 and least 13 more species have been assigned to the genus. The genus has been exclusively found in Cretaceous Burmese amber, which is dated to 99 million years ago. Description ''Burmesarchaea grimaldii'' is only known from a single male specimen preserved in amber. It is a small spider, with a body length of just under . Characteristic of the family Archaeidae, the head region is raised up from the thorax, although without the distinctive "neck" found in other genera in the family. It is presumed to have eight eyes (the posterior median eye is not visible); the anterior median eye is the largest. The chelicerae are long relative to the body at about , and project forward at about 45 degrees. The longest leg, the first, is long; the shortest, the third, is long. All the legs are without spines. The pedipalp has a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species dive ... (spiders) has the seventh-most species of all orders. The existence of the World Spider Catalog makes spiders the largest taxon with an online listing that is updated regularly. It ha ...

Saxony-Anhalt
Saxony-Anhalt (german: Sachsen-Anhalt ; nds, Sassen-Anholt) is a state of Germany, bordering the states of Brandenburg, Saxony, Thuringia and Lower Saxony. It covers an area of and has a population of 2.18 million inhabitants, making it the 8th-largest state in Germany by area and the 11th-largest by population. Its capital is Magdeburg and its largest city is Halle (Saale). The state of Saxony-Anhalt was formed in July 1945 after World War II, when the Soviet army administration in Allied-occupied Germany formed it from the former Prussian Province of Saxony and the Free State of Anhalt. Saxony-Anhalt became part of the German Democratic Republic in 1949, but was dissolved in 1952 during administrative reforms and its territory divided into the districts of Halle and Magdeburg. Following German reunification the state of Saxony-Anhalt was re-established in 1990 and became one of the new states of the Federal Republic of Germany. Saxony-Anhalt is renowned for its ri ...

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
