Eostrix
''Eostrix'' is a genus of extinct primitive owls in the family Protostrigidae, along with ''Oligostrix'' and ''Minerva''. These owls date from the early Eocene of the United States, Europe, and Mongolia. They have been described based on fossil remains. The genus was created by Pierce Brodkorb in 1971 to place a fossil species known until that time as ''Protostrix mimica''. The following species are recognised: * ''E. mimica'' described in 1938 by Alexander Wetmore using hindlimb elements in Eocene strata in Wyoming. * ''E. martinellii'' was described in 1972 from a left tarsometatarsus (lower leg bone) recovered from an escarpment above the southeastern bank of Cottonwood Creek in Fremont County, Wyoming by Jorge Martinelli on a field trip in 1970 under the auspices of the University of Kansas. The strata was a Lysite member of the Wind River Formation. Martinelli was studying paleontology at the University of Barcelona. Paleontologists Larry D. Martin and Craig Call Black from ...

Ypresiglaux
''Ypresiglaux'' (meaning "Ypresian owl") is an extinct genus of strigiform bird from the Early Eocene London Clay Formation of Essex, United Kingdom and Nanjemoy Formation of Virginia, United States. The genus contains two species: ''Y. michaeldanielsi'', known from a partial skeleton, and ''Y. gulottai'', known from a distal tarsometatarsus. Discovery and naming ''Ypresiglaux'' was described in 2022 by German paleontologist Gerald Mayr and British zoologist Andrew C. Kitchener. The generic name, "''Ypresiglaux''", combines a reference to the Ypresian-dated type locality with the Greek word "glaux," meaning "owl". The type species, ''Y. michaeldanielsi'', was described on the basis of a partial skeleton collected in 1992. This specimen, NMS.Z.2021.40.26, which includes the mandible, vertebrae, pectoral girdle, wing bones, and a partial right leg, was designated as the holotype. NMS.Z.2021.40.27, an additional specimen collected in 1982, consists of the distal portion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colin Harrison (ornithologist)
Colin James Oliver Harrison (18 August 1926 – 17 November 2003) was an English ornithologist. Harrison was born in London. He got a scholarship to grammar school, and then worked as a librarian and a teacher. He had been interested in birds since childhood, and joined an expedition to study autumn migration in Norway. He became a professional ornithologist at the age of 34 and became responsible for the care of the national collection of birds' nests and eggs in the Bird Room at the Natural History Museum at Tring, Hertfordshire. In 1966 he led the fourth of the series of Harold Hall Australian ornithological collecting expeditions. Harrison later became interested in biogeography and the museum's avian paleontological collection, on which he published a number of articles with Cyril Walker. He studied and published on different aspects of bird behaviour, on plumage patterns, and on the bone structure of modern and fossil birds. He identified ''Eostrix ''Eostrix'' is a g ...

Pierce Brodkorb
William Pierce Brodkorb (September 29, 1908, Chicago – July 18, 1992, Gainesville, Florida) was an American ornithologist and paleontologist. Interested in birds since childhood, he was taught to prepare birds at the age of 16. Later, he received the opportunity to work as a staff technician in the Ornithology Division of the Field Museum. He entered the University of Michigan in 1933 and obtained his PhD degree in 1936. Subsequently, he became an assistant curator of birds at the Museum of Zoology in Michigan until 1946. In 1946, he accepted a professorate in the Department of Zoology at the University of Florida in Gainesville, a position he held until his retirement in 1989. His doctoral students include Glen E. Woolfenden. From the 1950s, Brodkorb built up a huge collection of bird fossils from the Miocene, the Pliocene, and the Pleistocene of Florida, which included 12,500 skeletons from 129 families, and is on display at the Florida Museum of Natural History, part ...

Evgeny Kurochkin
Yevgeny Nikolayevich Kurochkin (Евгений Николаевич Курочкин; 12 July 1940 - 13 December 2011) was a Russian paleornithologist at the Paleontological Institute of the Russian Academy of Sciences. He served as President of the Menzbier Ornithological Society. He graduated from the Moscow State University in 1964. Most of his field work was done in Central Asia, Mongolia, Cuba, and Vietnam. In 1982, Kurochkin described '' Ambiortus'', which he thought to be the oldest ornithurine (modern-type bird). Kurochkin named the new species after his peer Georgi Petrovich Dementyev (1898-1969). In 2011, Kurochkin and Gareth J. Dyke described ''Eostrix tsaganica'' found in Mongolia, the first find of this primitive owl in Asia. Opposing the theropod origin of modern birds, Kurochkin maintained that archosaurs and dinosaurs were two distinct lineages. He repeatedly questioned the assumption that Archaeopteryx and Enantiornithes were early birds. According to Kurochkin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Eocene Birds Of North America
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status.
