Scaffold Web Spider
Scaffold web spiders (Nesticidae) is a family of araneomorph spiders closely allied with tangle web spiders. Like the "Theridiidae", these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. It contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus ''Nesticus'' is the type for the family and is found throughout the world. The related ''Eidmannella'' has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, ''Eidmannella pallida'', is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus '' Carpathonesticus'' is found in central Eurasia. Genera , the World Spider Catalog accepts the following genera: *'' Aituaria'' Esyunin & Efimik, 1998 — Ukraine, Russia, Georgia *'' Canarionesticus'' Wunderlich, 1992 — Canary Is. *' ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in his ...

Bitterfeld
Bitterfeld () is a town in the district of Anhalt-Bitterfeld, Saxony-Anhalt, Germany. Since 1 July 2007 it has been part of the town of Bitterfeld-Wolfen. It is situated approximately 25 km south of Dessau, and 30 km northeast of Halle (Saale). At the end of 2016, it had 40,964 inhabitants. History and description The name Bitterfeld most likely comes from the Middle High German words ''bitter'' and ''Feld'' and so means "boggy land". Bitterfeld was built by a colony of Flemish immigrants in 1153. The first documentary mention is from 1224. It was captured by the landgrave of Meissen in 1476, and belonged thenceforth to Saxony, until it was ceded to Prussia in 1815. By 1900, Bitterfeld station was an important junction of the Berlin–Halle and the Magdeburg–Leipzig railways. The population at that time was 11,839; it manufactured drainpipes, paper roofing, and machinery, and had sawmills. There were also several coal mines in the vicinity. Owing to its pleasant s ...

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...

Paleogene
The Paleogene ( ; British English, also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period, geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (annum, Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognised as a formal stratigraphy, stratigraphic term, 'Tertiary' is still widely found in earth science literature and remains in informal use. Paleogene is often abbreviated "Pg" (but the United States Geological Survey uses the abbreviation PE for the Paleogene on the Survey's geologic maps). During the Paleogene, evolution of mammals, mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of ...
