Mastotermes Electrodominicus
''Mastotermes'' is a genus of termites. The sole living species is ''Mastotermes darwiniensis'', found only in northern Australia. A number of extinct taxa are known from fossils. It is a very peculiar insect, the most primitive termite alive. As such, it shows notable similarities to certain cockroaches, the termites' closest relatives. These similarities include the anal lobe of the wing and the laying of eggs in bunches, rather than singly. The termites were traditionally placed in the Exopterygota, but such an indiscriminate treatment makes that group a paraphyletic grade of basal neopterans. Thus, the cockroaches, termites and their relatives are nowadays placed in a clade called Dictyoptera. These singular termites appear at first glance like a cockroaches abdomen with a termite's head and thorax. Their wings have the same design as those of the cockroaches, and its eggs are laid in a case as are cockroach eggs. It is thought to have evolved from the same ancestors ...

Mastotermes Darwiniensis
''Mastotermes darwiniensis'', common names giant northern termite and Darwin termite, is a termite species found only in northern Australia. It is the most primitive extant termite species. Evolutionary significance This species shows uncanny similarities to certain cockroaches, the termites' closest relatives. These similarities include the anal lobe of the wing and the laying of eggs in bunches, rather than singly. It is the only living member of its genus '' Mastotermes'' and its family Mastotermitidae, though numerous fossil taxa are known. The termites were traditionally placed in the Exopterygota, but such an indiscriminate treatment makes that group a paraphyletic grade of basal neopterans. Thus, the cockroaches, termites, and their relatives are nowadays placed in a clade called the Dictyoptera. These singular termites appear at first glance like a cockroach's abdomen stuck to a termite's fore part. Their wings have the same form as those of the roaches, and its eggs are ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mastotermes Electromexicus
''Mastotermes electromexicus'' is an extinct species of termite in the family Mastotermitidae known from a group of Late Oligocene to Early Miocene fossils found in Mexico. ''M. electromexicus'' is the only species in the genus '' Mastotermes'' to have been described from fossils found in Mexican amber and was the first member of the genus described from the New World. The only living species of ''Mastotermes'' is ''Mastotermes darwiniensis'' which is found in tropical regions of Northern Australia. History and classification ''Mastotermes electromexicus'' is known from a series of fourteen fossil insects which are inclusions in transparent chunks of Mexican amber. The amber specimens, a soldier, an imago and twelve nymphs are currently housed in the fossil collection of the University of California, Berkeley in Berkeley, California. The holotype fossil is composed of a partial soldier caste individual. Mexican amber is recovered from fossil bearing rocks in the Simojovel regio ...

Kumar Krishna
Kumar Krishna (21 June 1928-19 September 2014) was an American entomologist of Indian origin. He was an expert on the termites and published the definitive systematic treatment of the termites of the world in a seven volume ''Treatise on the Isoptera of the world'' in 2013 written with collaborators. Kumar was born in Rangoon and grew up in Dehra Dun where his father lived as an army physician who had served as a major in World War I. Kumar studied at the Agra University, receiving a Bachelor of Science in 1950 followed by a Master's degree from the University of Lucknow in 1952. He worked as a research assistant at the Forest Research Institute to Mithan Lal Roonwal, a specialist on termites and became very interested in the group. He moved to the University of Minnesota in 1954 and then moved to the University of Chicago to pursue a Ph.D. under Alfred E. Emerson (1896–1976). His research was on the dry wood termites in the family Kalotermitidae. He then worked at the City Colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Priabonian
The Priabonian is, in the ICS's geologic timescale, the latest age or the upper stage of the Eocene Epoch or Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. Stratigraphic definition The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona in the community of Monte di Malo, in the Veneto region of northern Italy. The base of the Priabonian Stage is at the first appearance of calcareous nannoplankton species ''Chiasmolithus oamaruensis'' (which forms the base of nanoplankton biozone NP18). An official GSSP was ratified in 2020, and was placed in the Alano di Piave section in Alano di Piave, Belluno, Italy. The top of the Priabonian Stage (the base of the Rupelian Stage and Oligocene Series) is at the extinction of foram genus ''Hantkenina''. Sometimes local rock ...

The Bouldnor Formation is a geological formation in the Hampshire Basin of southern England. It is the youngest formation of the Solent Group and was deposited during the uppermost Eocene and lower Oligocene. Stratotype and occurrence The Bouldnor Formation was named after Bouldnor, a small hamlet east of Yarmouth, Isle of Wight, Yarmouth, Isle of Wight. The formation is exposed along ''Bouldnor Cliff'' between Yarmouth and Hamstead, Isle of Wight, Hamstead occupying the core of the east-southeast-striking ''Bouldnor Syncline''. Yet the stratotype of the formation is found at ''Whitecliff Bay'' on the east side of the Isle of Wight. History The Bouldnor Formation was scientifically established 1985 by A. Insole and B. Daly, who also defined its member (geology), members. The paleogene strata on the Isle of Wight had already been described in 1853 by Edward Forbes. Forbes was followed in 1921 by H.J.O.
