Ektatotricha
''Ektatotricha'' is an extinct, monotypic, genus of ant-like stone beetle in the family Staphylinidae containing the single species ''Ektatotricha paradoxa''. The genus is known from a total of 15 specimens in amber from amber deposits near Tanai Village northwest of Myitkyina in the Kachin region of Myanmar. Burmese amber has been radiometrically dated using U- Pb isotopes, yielding an age of approximately 99 million years old, close to the Aptian – Cenomanian boundary. The holotype, a single, complete adult with specimen number "AMNH Bu-1464", and six of the paratypes are now deposited in the American Museum of Natural History. Four more of the paratypes are deposited in the University of Kansas Natural History Museum collections in Lawrence, Kansas, USA. The remaining two paratype specimens are currently in a private collection, but are to be deposited in the Field Museum of Natural History, Chicago. In addition to the holotype and 12 paratypes, two ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scydmaenidae
Scydmaeninae are a subfamily of small beetles, commonly called ant-like stone beetles or scydmaenines. These beetles occur worldwide, and the subfamily includes some 4,500 species in about 80 genera. Established as a family, they were reduced in status to a subfamily of Staphylinidae in 2009 Many scydmaenine species have a narrowing between head and thorax and thorax and abdomen, resulting in a passing resemblance to ants that inspires their common name. The largest measure just 3 millimeters long, while some very small species only reach half a millimeter in length. Scydmaenids typically live in leaf litter and rotting logs in forests, preferring moist habitats. A number of types are known to feed on oribatid mites, using "hole scraping" and "cutting" techniques to get through the mite's hard shells. In addition to the two living subfamilies, the prehistoric subfamily Hapsomelinae, known only from fossils, has been placed here. Selected genera *'' Cephennium'' *'' Elacatopho ...

Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22.

University Of Kansas Natural History Museum
The University of Kansas Natural History Museum is part of the University of Kansas Biodiversity Institute, a KU designated research center dedicated to the study of the life of the planet. The museum's galleries are in Dyche Hall on the university's main campus in Lawrence, Kansas. The galleries are open from 9 a.m. to 5 p.m. Tuesday through Saturday and noon to 4 p.m. on Sundays. Dyche Hall has been listed on the National Register of Historic Places since July 14, 1974; it was listed for its connection with Lewis Lindsay Dyche and for its distinctive Romanesque style of architecture. The exterior is constructed of local Oread Limestone, while the window facings, columns, arches, and grotesques are carved from Cottonwood Limestone. Dyche Hall is also the site of one of only three Victory Eagle statues in Kansas, once used as markers on the Victory Highway. Among its more than 350 separate exhibits, the museum is famous for its Panorama of North American Wildlife, part of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Beetle Genera
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the a ...
