Steleopteron Deichmuelleri
''Steleopteron deichmuelleri'' is a species of extinct winged damselfly in the family Steleopteridae, which lived in modern Germany during the Upper Jurassic era (150.8-145 million years ago). The holotype 1903.V3 1985/4, which is a dissociated exoskeleton, was found in the Lower Tithonian sediments at Eichstatt, Solnhofen, Bavaria, Germany. The Austrian paleoentomologist Anton Handlirsch described it in 1906. The body of the holotype reaches 60 mm in length and 3 mm in width, wings – 39 mm in length and 6 mm in width. They were fast insectivorous predators. The species belongs to the extinct insect family Steleopteridae, and the genus Steleopteron ''Steleopteon'' is a genus of extinct winged damselflies whose fossils have been found in modern Germany, and Great Britain, and which lived at the end of the Jurassic and the beginning of the Cretaceous (150.8 to 130 million years ago).

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but the ...

Steleopteridae
Steleopteridae is a family of extinct winged damselflies whose fossils have been found in modern Germany, Great Britain and Kazakhstan, and which lived at the end of the Jurassic and the beginning of the Cretaceous (166.1–130.0 million years ago). The family was described by the Austrian paleoentomologist Anton Handlirsch in 1906 on the basis of the fossilised exoskeleton ''Steleopteron deichmuelleri''. Hence, the type genus is ''Steleopteron''. Handlirsch assigned the family to the Epiproctophora. In 2001, the family was excluded from the Epiproctophora and transferred into a suborder of winged damselflies, Zygoptera. Until 2018, it had been believed that Steleopteridae became extinct in the Jurassic, but the discovery of ''Steleopteron cretacicus'' showed that the family may have become extinct as late as the Cretaceous. They were fast flying Insectivore, insectivorous/Carnivore, carnivorous predators. According to the Fossilworks Database website, as of November 2019, ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tithonian
In the geological timescale, the Tithonian is the latest age of the Late Jurassic Epoch and the uppermost stage of the Upper Jurassic Series. It spans the time between 152.1 ± 4 Ma and 145.0 ± 4 Ma (million years ago). It is preceded by the Kimmeridgian and followed by the Berriasian (part of the Cretaceous).See for a detailed version of the geologic timescale Gradstein ''et al.'' (2004) Stratigraphic definitions The Tithonian was introduced in scientific literature by German stratigrapher Albert Oppel in 1865. The name Tithonian is unusual in geological stage names because it is derived from Greek mythology. Tithonus was the son of Laomedon of Troy and fell in love with Eos, the Greek goddess of dawn. His name was chosen by Albert Oppel for this stratigraphical stage because the Tithonian finds itself hand in hand with the dawn of the Cretaceous. The base of the Tithonian stage is at the base of the ammonite biozone of '' Hybonoticeras hybonotum''. A global reference profi ...

Solnhofen
Solnhofen is a municipality in the district of Weißenburg-Gunzenhausen in the region of Middle Franconia in the ' of Bavaria in Germany. It is in the Altmühl valley. The local area is famous in geology and palaeontology for Solnhofen limestone. This is a very fine-grained limestone from the Jurassic period Lagerstätte that preserves detailed fossil specimens. Alois Senefelder used specially prepared blocks of the fine Solnhofen limestone for the process of lithography which he invented in 1798. The quarrying of this lithographic limestone subsequently yielded spectacular finds, including ''Archaeopteryx'', commemorated in the bird's full name ''Archaeopteryx lithographica''. All 13 known specimens have come from the Solnhofen area. Geography Solnhofen is located on the Altmühl in Bavaria. It contains two districts: Hochholz and Eßlingen. It is adjacent to the municipalities Pappenheim, Langenaltheim, and Mörnsheim. History Solnhofen was known as "Husen" in the eighth ...

Anton Handlirsch
Anton Handlirsch or Anton Peter Josef Handlirsch (20 January 1865, Vienna – 28 August 1935, Vienna) was an Austrian entomologist. He worked on many groups including Hemiptera, Hymenoptera and Neuroptera. His most significant work was in the study of fossil insects. Anton was born to Peter (1831–1873) and Rosina Handlirsch (born 1841). His father worked as a cook of the Schwarzenberg family. His surname Handlirsch came from cs, handlíř "merchant". He went to study at the Gymnasium in Vienna in 1875. Although he began to show an interest in zoology, his father wished that he obtain a degree in pharmacy. Anton obtained a master's degree in pharmacy in 1885. After working for a while as a pharmacist, Anton and his brother Adam met the entomologist Friedrich Moritz Brauer and Anton later became an assistant to him in the department of entomology of the Natural History Museum of Vienna in 1892. In the same year he married Martha Allounek. He became the director of this departmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steleopteron
''Steleopteon'' is a genus of extinct winged damselflies whose fossils have been found in modern Germany, and Great Britain, and which lived at the end of the Jurassic and the beginning of the Cretaceous (150.8 to 130 million years ago). The genus was described by the Austrian paleoentomologist Anton Handlirsch in 1906 on the basis of the fossilised exoskeleton ''Steleopteron deichmuelleri''. Until 2018, it had been believed that the genus became extinct in the Jurassic, but the discovery of ''Steleopteron cretacicus'' showed that the genus and the family may have become extinct as late as the Cretaceous. In 2001, Günther Fleck, Fleck and others transferred the family, Steleopteridae to a suborder of winged damselflies, Zygoptera. They were fast flying Insectivore, insectivorous/Carnivore, carnivorous predators. According to the Fossilworks Database website, as of November 2019, the genus includes two extinct species: *''Steleopteron cretacicus'' Zheng et al. 2018 *''Stele ...

Steleopteron Cretacicus
''Steleopteron cretacicus'' (lat.) is a species of extinct winged damselfly from the Jurassic family Steleopteridae that lived in modern Britain during the Early Cretaceous era (136.4–130 million years ago). It is the first member of the Steleopteridae family, to be found living during the Cretaceous period, to be described, and belongs to the genus Steleopteron. There is a sister taxon – ''Steleopteron deichmuelleri''. The discovery of the species showed that the family Steleopteridae had not died out by the Cretaceous period. These damselflies were fast insectivorous predators. The species name refers to the fact that the species existed in the Cretaceous period. Holotype The holotype, NHMUK CH 879vii, a fossilized wing, was found n lagoonal sediments in the Weald formation (136.4 – 130.0 Ma) in Surrey, United Kingdom. In 2018, Daran Zheng, A. Nel, and Edmund A. Jarzembowski described the species. The specimen is stored in the Department of Earth Sciences, Museu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
