Steleopteron Cretacicus Sp
''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, Fleck and others transferred the family, Steleopteridae to a suborder of winged damselflies, Zygoptera. They were fast flying insectivorous/carnivorous predators. According to the Fossilworks Database website, as of November 2019, the genus includes two extinct species: *''Steleopteron cretacicus'' Zheng et al. 2018 *''Steleopteron deichmuelleri ''Steleoptero ...

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] |
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).

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] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

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] |

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, ...

Insectivore
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivore
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats (felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbivorous. ...

Prehistoric Insect Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
