Gymnogyps Varonai
''Gymnogyps varonai'', sometimes called the Cuban condor, is an extinct species of large New World vulture in the family Cathartidae. ''G. varonai'' is related to the living California condor, ''G. californianus'' and the extinct '' G. kofordi'', either one of which it may have evolved from. The species is solely known from fossils found in the late Pleistocene to early Holocene tar seep deposits in Cuba. ''G. varonai'' may have preyed upon carcasses from large mammals such as ground sloths. History and classification The species is known from at least six fragmentary fossils housed in the Museo Nacional de Historia Natural in Havana, Cuba, and includes a premaxilla, coracoid, the basal end of a right radius. The specimens were collected from the Las Breas de San Felipe tar seep site San Filipe II, which is located west of Martí, Cuba. Based on the geology of the sites, the seeps are suggested to date from the Quaternary, being younger than the weathered serpentinites ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Birds Of The Caribbean
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, mam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene Birds Of North America
The Pleistocene ( , often referred to as the ''Ice age'') is the geological 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 a faunal interchange between the two reg ...

Fossils Of Cuba
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolut ...

New World Vultures
The New World vulture or condor family, Cathartidae, contains seven extant species in five genera. It includes five extant vultures and two extant condors found in warm and temperate areas of the Americas. The "New World" vultures were widespread in both the Old World and North America during the Neogene. Old World vultures and New World vultures do not form a single clade, but the two groups are similar in appearance due to convergent evolution. Vultures are scavenging birds, feeding mostly from carcasses of dead animals without apparent ill effects. Bacteria in the food source, pathogenic to other vertebrates, dominate the vulture's gut flora, and vultures benefit from the bacterial breakdown of carrion tissue. Some species of New World vulture have a good sense of smell, whereas Old World vultures find carcasses exclusively by sight. A particular characteristic of many vultures is a bald head, devoid of feathers. Taxonomy and systematics The New World vultures comprise seven ...

Gymnogyps
''Gymnogyps'' is a genus of New World vultures in the family Cathartidae. There are five known species in the genus, with only one being extant, the California condor. Fossil species *''Gymnogyps amplus'' was first described by L. H. Miller in 1911 from a broken tarsometatarsus. The species is the only condor species found in the La Brea Tar Pits' Pit 10, which fossils date to "a Holocene radiocarbon age of 9,000 years." The smaller, modern California condor may have evolved from ''G. amplus''. *''Gymnogyps howardae'' was described from the Late Pleistocene (Lujanian) asphalt deposits known as the Talara Tar Seeps, near Talara, northwestern Peru. It lived about 126,000-12,000 years ago. *''Gymnogyps kofordi'' was described based on a right tarsometatarsus. *'' Gymnogyps varonai'' is known from fossils found in the late Pleistocene to early Holocene tar seep deposits in Cuba Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island co ...

Acratocnus
''Acratocnus'' is an extinct genus of ground sloths that were found on Cuba, Hispaniola (today the Dominican Republic and Haiti), and Puerto Rico. Classification Like all of the Antillean sloths, ''Acratocnus'' was formerly thought on the basis of morphological evidence to be a member of the family Megalonychidae, which was also thought to include '' Choloepus'', the two-toed tree sloths. Recent molecular evidence has clarified that Caribbean sloths represent a separate basal branch of the sloth radiation, now placed in the family Megalocnidae. Location Fossils of ''Acratocnus'' were found on the islands of Puerto Rico, Cuba, and Hispaniola, where they inhabited the montane forests of the highlands. The Puerto Rican ground sloth, ''Acratocnus odontrigonus'' is known from several poorly documented cave excavations in northwestern Puerto Rico. The various species are regarded as being semi-arboreal because of their (relatively speaking) small size and their large hooked cla ...

Megalocnus
''Megalocnus'' ("great sloth" in Greek) is a genus of extinct large ground sloths that were native to Cuba during the Pleistocene and Holocene epochs. They were among the largest of the Caribbean sloths (Megalocnidae), with individuals estimated to have weighed up to 270 kg (595 lbs) to 200 kg (440 lbs), around the size of a black bear when alive.Steadman, D. W., Martin, P. S., MacPhee, R. D., Jull, A. T., McDonald, H. G., Woods, C. A., ... & Hodgins, G. W. (2005). Asynchronous extinction of late Quaternary sloths on continents and islands. ''Proceedings of the National Academy of Sciences'', ''102''(33), 11763-11768. Its relatives include other megalocnid sloths, such as '' Acratocnus'', '' Mesocnus'', '' Miocnus'', '' Neocnus and'' '' Parocnus''. The former species ''M. zile'' from Hispaniola is currently thought to be a junior synonym of ''Parocnus serus''.
