Cuban Giant Owl
The Cuban giant owl or giant cursorial owl (''Ornimegalonyx'') is an extinct genus of giant owl that measured in height. It is closely related to the many species of living owls of the genus ''Strix''.Feduccia, Alan (1996) "The Origin and Evolution of Birds" Yale University Press It was a flightless or nearly flightless bird and it is believed to be the largest owl that ever existed. It lived on the island of Cuba. The first fossil specimen was mistakenly described as a bird in the family Phorusrhacidae, in part because the bones were so large. In 1961, Pierce Brodkorb reviewed the findings and placed them properly, with the owls. Remains have been abundant throughout the island, in cave deposits from the Late Pleistocene period (126,000 to 11,700 years ago) and at least three nearly complete skeletons have been found. Taxonomy In the past, three additional species of ''Ornimegalonyx'' besides ''O. oteroi'' were regarded as valid. All were described in 1982 and include: *''Ornim ...

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 ...

Burrowing Owl
The burrowing owl (''Athene cunicularia''), also called the shoco, is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other open, dry area with low vegetation. They nest and roost in burrows, such as those excavated by prairie dogs (''Cynomys'' spp.). Unlike most owls, burrowing owls are often active during the day, although they tend to avoid the midday heat. Like many other kinds of owls, though, burrowing owls do most of their hunting during dusk and dawn, when they can use their night vision and hearing to their advantage. Living in open grasslands as opposed to forests, the burrowing owl has developed longer legs that enable it to sprint, as well as fly, when hunting. Taxonomy The burrowing owl was formally described by Spanish naturalist Juan Ignacio Molina in 1782 under the binomial name ''Strix cunicularia'' from a specimen collected in Chi ...

Miocnus
''Miocnus'' is an extinct genus of ground sloths of the family Megalocnidae endemic to Cuba during the Pleistocene and very early Holocene epochs, living from 1.8  Mya—11,000 years ago, existing for approximately . Taxonomy ''Miocnus'' was named by Matthew (1931). Its type is ''Miocnus antillensis''. It was assigned to Megalonychidae Megalonychidae is an extinct family of sloths including the extinct ''Megalonyx''.

Ground Sloth
Ground sloths are a diverse group of extinct sloths in the mammalian superorder Xenarthra. The term is used to refer to all extinct sloths because of the large size of the earliest forms discovered, compared to existing tree sloths. The Caribbean ground sloths, the most recent survivors, lived in the Antilles, possibly until 1550 BCE. However, radiocarbon dating suggests an age of between 2819 and 2660 BCE for the last occurrence of ''Megalocnus'' in Cuba. Ground sloths had been extinct on the mainland of North and South America for 10,000 years or more. They survived 5,000–6,000 years longer in the Caribbean than on the American mainland, which correlates with the later colonization of this area by humans. Much ground sloth evolution took place during the late Paleogene and Neogene of South America, while the continent was isolated. At their earliest appearance in the fossil record, the ground sloths were already distinct at the family level. The presence ...

Capybara
The capybaraAlso called capivara (in Brazil), capiguara (in Bolivia), chigüire, chigüiro, or fercho (in Colombia and Venezuela), carpincho (in Argentina, Paraguay and Uruguay) and ronsoco (in Peru). or greater capybara (''Hydrochoerus hydrochaeris'') is a giant cavy rodent native to South America. It is the largest living rodent and a member of the genus ''Hydrochoerus''. The only other extant member is the lesser capybara (''Hydrochoerus isthmius''). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the nutria. The capybara inhabits savannas and dense forests, and lives near bodies of water. It is a highly social species and can be found in groups as large as 100 individuals, but usually live in groups of 10–20 individuals. The capybara is hunted for its meat and hide and also for grease from its thick fatty skin. It is not considered a threatened species. Etymology Its common name is derived fro ...

Nutria
The nutria (''Myocastor coypus''), also known as the coypu, is a large, herbivorous, semiaquatic rodent. Classified for a long time as the only member of the family Myocastoridae, ''Myocastor'' is now included within Echimyidae, the family of the spiny rats. The nutria lives in burrows alongside stretches of water, and feeds on river plant stems. Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur farmers. Although it is still hunted and trapped for its fur in some regions, its destructive burrowing and feeding habits often bring it into conflict with humans, and it is considered an invasive species. Nutria also transmit various diseases to humans and animals mainly through water contamination. Etymology The genus name ''Myocastor'' derives from the two Ancient Greek words (), meaning "rat, mouse", and (), meaning "beaver". Literally, therefore, the name ''Myocastor'' means ...

Geocapromys
''Geocapromys'' is a genus of rodent belonging to the hutia subfamily and are currently only found on the Bahamas and Jamaica. However, they formerly ranged throughout the Caribbean, from Cuba to the Cayman Islands to even islands off mainland Central America. Systematics The genus ''Geocapromys'' comprises five recent species, three of which are extinct. * ''Geocapromys ingrahami'', the Bahamian hutia or Ingraham's hutia, is an extant species of hutia native to the Bahamas. * ''G. brownii'', the Jamaican hutia, which is also known as the Jamaican coney or Brown's hutia, is another extant species endemic to Jamaica. * ''G. thoracatus'', the Little Swan Island hutia, was a third species which was found only on Little Swan Island, off northeastern Honduras. It became extinct in 1955, wiped out by storms and introduced predators. Some scientists consider it a subspecies of ''G. brownii''. *''G. columbianus'', the Cuban coney, was endemic to Cuba, where it went extinct shortly after ...

Hutia
Hutias (known in Spanish as jutía) are moderately large cavy-like rodents of the subfamily Capromyinae that inhabit the Caribbean islands, with most species restricted to Cuba and Hispaniola. Twenty species of hutia have been identified, but at least half are extinct. Only Desmarest's hutia and the prehensile-tailed hutia remain common and widespread; all other extant species are considered threatened by the IUCN. The extinct giant hutias of the family Heptaxodontidae also inhabited the Caribbean, but are not thought to be closely related, with the giant hutias belonging in the superfamily Chinchilloidea. Description Most species have a head-and-body length that ranges from and weigh less than , but Desmarest's hutia has a head-and-body length of and weighs . They resemble the coypu in some respects. Tails are present, varying from vestiges to prehensile. They have stout bodies and large heads. Most species are herbivorous, though some consume small animals. Instead of burro ...
