Oscaravis
''Oscaravis olsoni'' (also known as the Cuban teratorn), of the teratorn family, was a large, predatory bird that roamed the territory that is now modern-day Cuba before going extinct at the end of the Pleistocene era. Previously classified as ''Teratornis olsoni'', it has recently been granted a new genus due to its ecological isolation from others in the teratorn family, as well as differences in size and possibly behavior. Although no exact measurements can be stated, due to recent archaeological findings and the comparison of ''O. olsoni'' bone lengths with that of other teratorns, it has been concluded ''Oscaravis olsoni'' would have had a body bigger than '' Taubatornis campbelli'' but smaller than '' Cathartornis gracilis''. Ecology ''Oscaravis olsoni'' was most prominently located in modern-day Cuba, as well as the outlying islands at the time. Due to their massive size and wingspan, it was believed that many members of the family Teratornithidae, especially ''Oscaravis o ...

Teratornithidae
Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to the Late Pleistocene. They include some of the largest known flying birds. Taxonomy Teratornithidae are related to New World vultures (Cathartidae, syn. Vulturidae). So far, at least seven species in six genera have been identified: * '' Teratornis'' ** ''Teratornis merriami''. This is by far the best-known species. Over 100 specimens have been found, mostly from the La Brea Tar Pits. It stood about tall with an estimated wingspan of perhaps , and weighed about ; making it about a third bigger than extant condors. It became extinct at the end of the Pleistocene, some 10,000 years ago. ** ''Teratornis woodburnensis''. The first species to be found north of the La Brea Tar Pits, this partial specimen was discovered at Legion Park, Woodburn, Oregon. It is known from a humerus, parts of the cranium, beak, sternum, and vertebrae which indicate an estima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teratornis
''Teratornis'' (Greek: "wonder" (teretos), "bird" (ornis)) was a genus of huge North American birds of prey – the best-known of the teratorns - of which, two species are known to have existed: ''Teratornis merriami'' and ''Teratornis woodburnensis''. A large number of fossil and subfossil bones, representing more than 100 individuals, have been found in locations in California, Oregon, southern Nevada, Arizona, and Florida, though most are from the Californian La Brea Tar Pits. All remains except one Early Pleistocene partial skeleton from the Leisey Shell Pit near Charlotte Harbor, Florida (which may represent a different species or a subspecies) date from the Late Pleistocene, with the youngest remains dating from the Pleistocene-Holocene boundary. Taxonomy * ''Teratornis merriami''. This is by far the best-known species. Over a hundred specimens have been found, mostly from the La Brea Tar Pits. It stood about 75 cm (29.5 in) tall with estimated wingspan of perhaps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cathartornis Gracilis
''Cathartornis'' is an ancient bird of the Teratornithidae family. It lived somewhere between 23 million years (Miocene Epoch) and 10,000 years (Pleistocene Epoch) ago. The only evidence of the bird's existence is a few bones. Its remains were documented in 1910. ''Cathartornis'' was described on the basis of 2 tarsometatarsi, 1 complete and 1 containing only the distal end, recovered from the Pleistocene La Brea Tar Pits in Southern California. Since then, no other fossils have officially been referred to the taxon, though some fossils assigned to ''Teratornis ''Teratornis'' (Greek: "wonder" (teretos), "bird" (ornis)) was a genus of huge North American birds of prey – the best-known of the teratorns - of which, two species are known to have existed: ''Teratornis merriami'' and ''Teratornis woodburnen ...'' could be from ''Cathartornis'' and unpublished remains have been mentioned.Campbell, K.

Argentavis Magnificens
''Argentavis magnificens'' was among the largest flying birds ever to exist. While it is still considered the heaviest flying bird of all time, ''Argentavis'' was likely surpassed in wingspan by '' Pelagornis sandersi'' which is estimated to have possessed wings some 20% longer than ''Argentavis'' and which was described in 2014. ''A. magnificens'', sometimes called the Giant Teratorn, is an extinct species known from three sites in the Epecuén and Andalhualá Formations in central and northwestern Argentina dating to the Late Miocene (Huayquerian), where a good sample of fossils has been obtained.''Argentavis'' at Fossilworks.org Description The single known[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...
