Victor Motschulsky
Victor Ivanovich Motschulsky, sometimes Victor von Motschulsky ( Russian: Виктор Иванович Мочульский; 11 April 1810, St. Petersburg – 5 June 1871, Simferopol) was a Russian entomologist mainly interested in beetles. Motschulsky was an Imperial Army colonel who undertook extended trips abroad. He studied and described many new beetles from Siberia, Alaska, the United States, Europe, and Asia. While he tended to ignore previous work and his own work on classification was of poor quality, Motschulsky made a massive contribution to entomology, exploring hitherto unworked regions, often in very difficult terrain. He described many new genera and species, a high proportion of which remain valid. Travels Motschulsky's travels included: *1836 - France, Switzerland and the Alps, northern Italy and Austria *1839–1840 - Russian Caucasus, Astrakhan, Kazan and Siberia *1847 - Khirgizia *1850–1851 - Germany, Austria, Egypt, India, France, England, Belgium an ...

David Sharp (entomologist)
David Sharp (18 October 1840 – 27 August 1922) was an English physician and entomologist who worked mainly on Beetle, Beetles. He was among the most prolific publishers in the history of entomology with more than 250 papers that included seven major revisions and reviews and a highly influential work on the structure and modifications of the male genital structures of beetles. He edited ''The Zoological Record'' for three decades. Biography David Sharp was born at Towcester and lived his early years in Stony Stratford. Some twelve years later his parents moved to London, where he received most of his education. After attending one or two preparatory schools, in 1853 he entered St. John's Foundation School which was then at Kilburn, London, Kilburn. At the age of seventeen he commenced to help his father, a leather merchant, and about the same time he began collecting beetles, some of his favourite haunts being Ken Wood and Hammersmith Marshes, as well as the sandy shores abo ...

Myxophaga
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae. Description Myxophaga have several diagnostic features: the antennae are more or less distinctly clubbed with usually fewer than nine segments, mesocoxal cavities are open laterally and bordered by a mesepimeron and metanepisternum, the hind wings are rolled apically in the resting positions. Internally, they are characterised by the presence of six malpighian tubules and the testes are tube-like and coiled. Beetles of this suborder are adapted to feed on algae. Their mouthparts are characteristic in lacking galeae and having a mobile tooth on their left mandible. Taxonomy There are four extant families in the suborder Myxophaga divided between two superfamilies, containing about 65 described species, and at least one extinct family. Superfamil ...

Neotropics
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean Islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...

Cenomanian
The Cenomanian is, in the International Commission on Stratigraphy's (ICS) geological timescale, the oldest or earliest age (geology), age of the Late Cretaceous epoch (geology), Epoch or the lowest stage (stratigraphy), stage of the Upper Cretaceous series (stratigraphy), Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to the potential role of the amber trade in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found in the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within north ...
