Electrostephanus Brevicornis
''Electrostephanus'' is an extinct genus of crown wasp in the hymenopteran family Stephanidae, and is the only genus placed in the subfamily Electrostephaninae. The genus contains four described species, ''E. brevicornis'', ''E. neovenatus'', ''E. janzeni'', and ''E. petiolatus'', placed in two subgenera ''E. (Electrostephanus)'' and ''E. (Electrostephanodes)''. ''Electrostephanus'' is known from several middle Eocene fossils which have been found in Europe. History and classification ''Electrostephanus'' is known from a group of fossils preserved as an inclusions in transparent chunks of Baltic amber and is named after the Greek term for amber, ἤλεκτρον (elektron). Baltic amber is approximately forty-six million years old, having been deposited during Lutetian stage of the Middle Eocene. There is debate as to what plant family the amber was produced by, with evidence supporting relatives of either ''Agathis'' or ''Pseudolarix'' trees. The genus was originally descr ...

Idiognathoides
''Idiognathoides'' is an extinct genus of conodonts. Glen K. Merrill stated in 1963 that "conodont workers have considered ''Idiognathoides'' to be a junior synonym of '' Polygnathodella'' but it now proves to be a junior synonym of '' Cavusgnathus''. ''Polygnathodella'' and ''Cavusgnathus'' are shown to form a transitional series."Polygnathodella Harlton, 1933, or Idiognathoides Harris and Hollingsworth, 1933? Glen K. Merrill, Journal of Paleontology, March 1963, volume 37, issue 2abstract Use in stratigraphy The Bashkirian, the oldest age of the Pennsylvanian (also known as Upper Carboniferous), contains six biozones based on conodont index fossils, one of which contains an ''Idiognathoides'' species : the zone of ''Idiognathoides sinuatus''. The base of the Moscovian, the second stage in the Pennsylvanian, is close to the first appearances of the conodonts '' Declinognathodus donetzianus'' and ''Idiognathoides postsulcatus''.

Edward Branson
Edwin Bayer Branson (May 11, 1877 – March 12, 1950) was an American geologist and paleontologist. He was a professor of geology at the University of Missouri for 37 years. Biography Branson was born in Belleville, Kansas, one of six children of John McDowell Branson and Harriet Melviney Bullen. He married Grace Muriel Colton in 1905 in Massachusetts. They had two sons, Carl Colton Branson and Edwin Robert Branson, both of whom became geologists. From 1895–99, he taught in public schools in Powhattan, Kansas. He first attended Salina Normal University in Kansas and Valparaiso University in Indiana before attending the University of Kansas, earning a bachelor's degree in 1900 and a master's in 1903. He earned his doctorate from the University of Chicago in 1905. After a long career at the University of Missouri, he retired in 1947. Three years later, he died of a heart condition in Columbia, Missouri, aged 77. Academic career After earning his doctorate, Branson taught at ...

Maurice Mehl
Maurice Goldsmith Mehl (1887 - 1966) was an American paleontologist and professor in the geology department at the University of Missouri. Life and career Mehl was born on December 25, 1887, to Frank and Rebecca Goldsmith Mehl. After graduation from Burlingame High School, he attended the University of Chicago, where he completed a B.S. in 1911 and a Ph.D. in 1914. While at Chicago, he met Lucy Jane Hull and they were married in 1912. At Chicago, Mehl studied vertebrate paleontology under the instruction of prominent paleontologist Samuel Wendell Williston. He taught at Chicago for a while as well as at University of Wisconsin, University of Oklahoma, and Denison University before joining the University of Missouri in 1919. In addition to teaching and researching at Missouri until his retirement in 1958, where he was known as "Doc" Mehl, he also worked as a consultant to the Missouri Geological Survey and Water Resources. While at Missouri, he had a long and productive collab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neotype Male Of Electrostephanus Petiolatus Brues In Baltic Amber (AMNH B-JWJ-260)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is al ...

Stephanidae
The Stephanidae, sometimes called crown wasps, are a family (biology), family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered Cosmopolitan distribution, cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contain four extinct genera described from both compression fossils and inclusion (mineral), inclusions in amber. Biology Stephanids are noted for their ocellar corona, a semicircular to circular set of projections around the middle Simple eye in invertebrates, ocellus, forming a "crown" on the head. Only stephanids and the similarly old Hymenoptera family Orussidae have ocellar coronae, and it is uncertain if they developed the structure separately or if a common ancestor of both developed it and it was then lost in all but the two families. Weakly developed grooves starting at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
