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 ...

Minerva (bird)
''Minerva'' is an extinct genus of owls in the prehistoric family Protostrigidae from the Eocene of North America. Described in 1915 by Robert Wilson Shufeldt, R. W. Shufeldt, some of the bones of ''Minerva'' were interpreted as belonging to an edentate mammal by Alexander Wetmore in 1933, who assigned the remaining bones to the new genus ''Protostrix''. Analysis in 1983 re-established the genus ''Minerva'' was avian. References Extinct birds of North America Protostrigidae Eocene birds Birds described in 1915 {{Strigiformes-stub ...

Cécile Mourer-Chauviré
Cécile Mourer-Chauviré (born 1939) is a French paleontologist specializing in birds of the Eocene and the Oligocene. In her early career, she discovered with her husband the Laang Spean cave site of prehistoric humans in Cambodia. Career Cécile Chauviré was born on 5 November 1939 in Lyon, France. She studied at University of Lyon. Her early work was on large Quaternary mammals. She then proceeded in 1961 to a doctorate in Centre national de la recherche scientifique focusing on Pleistocene birds, a topic few at the time studied in France or Europe. Following her marriage in 1964 to Roland Mourer, she relocated to Cambodia where he was assigned by the French military as a "coopérant" in Kampong Chhnang (city), Kampong Chhnang. In 1965 she was appointed as a geology professor at Royal University of Phnom Penh, a post she held until the civil war in 1970. During this time she discovered with her husband the Laang Spean cave site of prehistoric humans.Sophady, Heng, et al. "La ...

Tibiotarsus
The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae. These small ornithischian dinosaurs were unrelated to birds and the similarity of their foot bones is best explained by convergent evolution. See also *Bird anatomy References * Proctor, Nobel S.

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] |
