Minerva (bird)
''Minerva'' is an extinct genus of owls in the prehistoric family Protostrigidae from the Eocene of North America. Described in 1915 by R. W. Shufeldt, some of the bones of ''Minerva'' were interpreted as belonging to an edentate mammal by Alexander Wetmore Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. He was also an elected member of both the American Philosophical Soc ... 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 ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, 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 isoto ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Robert Wilson Shufeldt
Robert Wilson Shufeldt Jr. (December 1, 1850January 21, 1934) was an American osteologist, myologist, museologist and ethnographer who contributed to comparative studies of bird anatomy and forensic science. He hated black people, strongly approved of the Ku Klux Klan, and was a proponent of white supremacy. A scandal and subsequent divorce from his second wife, the granddaughter of the famous ornithologist John James Audubon, led to a landmark judgment by the Supreme Court of the United States of America on the subject of alimony and bankruptcy. Life and career Son of Admiral Robert Wilson Shufeldt and Sarah Shufeldt, he was born in New York in 1850. After a school education in the United States and Havana, he joined as a Captain's clerk on the US Gunboat which was under the command of his father. In 1872 he joined Cornell University to study medicine and obtained a degree in 1876 from Columbian, Washington, D.C. He joined the Medical Department of the Army as a Lieuten ...

Alexander Wetmore
Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. He was also an elected member of both the American Philosophical Society and the United States National Academy of Sciences. Early life and education The son of a physician, Frank Alexander Wetmore was born in North Freedom, Wisconsin. Developing an interest in birds at an early age, he made his first field journal entry (a pelican seen while on vacation in 1894) at the age of eight. By 1900, Wetmore published his first paper "My Experience with a Red-headed Woodpecker," in the magazine Bird-Lore. To further his education Wetmore enrolled at the University of Kansas in 1905. During his studies there he did a stint as an assistant in the University Museum, under the direction of Charles D. Bunker. Alexander Wetmore later received his BA from the University of Kansas in 1912; finally receiving his MS in 19 ...

Minerva Antiqua
Minerva (; ; ) is the Roman goddess of wisdom, justice, law, victory, and the sponsor of arts, trade, and strategy. She is also a goddess of warfare, though with a focus on strategic warfare, rather than the violence of gods such as Mars. Beginning in the second century BC, the Romans equated her with the Greek goddess Athena.''Larousse Desk Reference Encyclopedia'', Book People, Haydock, 1995, p. 215. Minerva is one of the three Roman deities in the Capitoline Triad, along with Jupiter and Juno. Minerva is a virgin goddess. Her domain includes music, poetry, medicine, wisdom, commerce, weaving, and the crafts. Minerva is often depicted with her sacred creature, an owl usually named the "owl of Minerva" which symbolised her association with wisdom and knowledge, as well as, less frequently, the snake and the olive tree. Minerva is commonly depicted as tall with an athletic and muscular build. She is often wearing armour and carrying a spear. As an important Roman goddess, s ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Edentate
Xenarthra (; from Ancient Greek wikt:ξένος, ξένος, xénos, "foreign, alien" + wikt:ἄρθρον, ἄρθρον, árthron, "joint") is a Order (biology), superorder and major clade of Placentalia, placental mammals native to the Americas. There are 31 living species: the anteaters, tree sloths, and armadillos. Extinct xenarthrans include the glyptodonts, Pampatheriidae, pampatheres and ground sloths. Xenarthrans originated in South America during the late Paleocene about 60 million years ago. They evolved and diversified extensively in South America during the continent's long period of isolation in the early to mid Cenozoic Era. They spread to the Antilles by the early Miocene and, starting about 3 million years ago, spread to Central America, Central and North America as part of the Great American Interchange. Nearly all of the formerly abundant megafaunal xenarthrans Quaternary extinction event, became extinct at the end of the Pleistocene. Characteristics Xenarthrans ...
