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 fro ...

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 Species description, described in 2022 by German zoologist Gerald Mayr and British zoologist Andrew C. Kitchener. The Genus, generic name, "''Ypresiglaux''", combines a reference to the Ypresian-dated type locality with the Greek language, Greek word "glaux," meaning "owl". The type species, ''Y. michaeldanielsi'', was described on the basis of a partial skeleton collected in 1992. This specimen, National Museums Scotland, NMS.Z.2021.40.26, which includes the mandible, vertebrae, pectoral girdle, wing bones, and a partial right leg, was designated as the holotype.

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 Biogeography is the study of the species distribution, distribution of species and ecosystems in geography, geographic space and through evolutionary history of life, geological time.

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 Kur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eocene Birds Of North America
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). 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.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 c ...
