Jaguar
The jaguar (''Panthera onca'') is a large felidae, cat species and the only extant taxon, living member of the genus ''Panthera'' that is native to the Americas. With a body length of up to and a weight of up to , it is the biggest cat species in the Americas and the List of largest cats, third largest in the world. Its distinctively marked Animal coat, coat features pale yellow to tan colored fur covered by spots that transition to Rosette (zoology), rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the Turtle shell#Carapace, carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range ex ...

Panthera Onca Mesembrina
''Panthera onca mesembrina'', also known as the Patagonian panther, is an extinct subspecies of jaguar (''Panthera onca'') that was endemic to southern Patagonia during the late Pleistocene epoch. It is known from several fragmentary specimens, the first of which found was in 1899 at " Cueva del Milodon" in Chile. These fossils were referred to a new genus and species "Iemish listai" by naturalist Santiago Roth, who thought they might be the bones of the mythological iemisch of Tehuelche folklore. A later expedition recovered more bones, including the skull of a large male that was described in detail by Angel Cabrera in 1934. Cabrera created a new name for the giant felid remains, ''Panthera onca mesembrina'', after realizing that its fossils were near-identical to modern jaguars’. ''P. onca mesembrina''s validity is disputed, with some paleontologists suggesting that it is a synonym of '' Panthera atrox''. The bones of ''P. onca mesembrina'' are nearly double the size of ...

Panthera
''Panthera'' is a genus within the family (biology), family Felidae, and one of two extant genera in the subfamily Pantherinae. It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger. Numerous extinct species are also named, including the Panthera spelaea, cave lion and American lion. Etymology The word derives from Classical Latin , itself from the Ancient Greek (). Characteristics In ''Panthera'' species, the dorsal profile of the skull is flattish or evenly convex. The frontal interOrbit (anatomy), orbital area is not noticeably elevated, and the area behind the elevation is less steeply sloped. The basic Cranial cavity, cranial axis is nearly horizontal. The inner chamber of the Auditory bulla, bullae is large, the outer small. The partition between them is close to the external auditory meatus. The convexly rounded chin is sloping. All ''Panthera'' species have an incompletely ossified h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosette (zoology)
A rosette is a rose-like Animal markings, marking or formation found on the fur and skin of some animals, particularly Felidae, cats. Rosettes are used to camouflage the animal, either as a defense mechanism or as a stalking tool. Predators use their rosettes to simulate the different shifting of shadows and shade, helping the animals to remain hidden from their prey. Rosettes can be grouped in clusters around other spots, or may appear as blotches on the fur. Leopard The leopard (''Panthera pardus'') has a wide variety of coat coloration. On each color variation, the leopard has rosette patterns on their backs, flanks, and limbs. They also have patterns that are considered to be spots and not rosettes on their heads, stomach, and limbs. Jaguar Like the leopard, the jaguar (''Panthera onca'') has a wide variety of coat coloration. The jaguar can have a coat in colors ranging from white to black with the most common residing in brownish yellow area. These big cats have rose ...

Panthera Onca Augusta
''Panthera onca augusta'' is an Extinction, extinct subspecies of the jaguar that was endemic to North America from Middle Pleistocene, Middle to Late Pleistocene epoch. Description ''P. o. augusta'' was 15-20% larger than most Jaguar populations. During the Irvingtonian, this subspecies could’ve averaged , with the largest individual weighing , but the subspecies went through a downsize with Rancholabrean populations being smaller than Irvingtonian populations. History and distribution Although ''P. onca'' still resides in the southern United States and several Native American tales possibly about ''P. onca augusta'' exist, the first published remains were described in 1872. The fossils were found by Ferdinand Vandeveer Hayden on the Platte River of Nebraska and sent to Joseph Leidy at the Academy of Natural Sciences of Drexel University, Academy of Natural Sciences in Philadelphia, who named them ''Felis augustus'' in 1872. The fossils consisted of a premolar IV and maxilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanistic
Melanism is the congenital excess of melanin in an organism resulting in dark pigment. Pseudomelanism, also called abundism, is another variant of pigmentation, identifiable by dark spots or enlarged stripes, which cover a large part of the body of the animal, making it appear melanistic. The morbid deposition of black matter, often of a malignant character causing pigmented tumors, is called melanosis. Adaptation Melanism related to the process of adaptation is called adaptive. Most commonly, dark individuals become fitter to survive and reproduce in their environment as they are better camouflaged. This makes some species less conspicuous to predators, while others, such as leopards, use it as a foraging advantage during night hunting. Typically, adaptive melanism is heritable: A dominant allele, which is entirely or nearly entirely expressed in the phenotype, is responsible for the excessive amount of melanin. By contrast, adaptive melanism associated with Batesian mimic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Felidae
Felidae ( ) is the Family (biology), family of mammals in the Order (biology), order Carnivora colloquially referred to as cats. A member of this family is also called a felid ( ). The 41 extant taxon, extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas. Some wild cat species are adapted to forest and savanna habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to Diurnality, diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the Pantherinae, the Felinae and the Acin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Paraguay
Paraguay, officially the Republic of Paraguay, is a landlocked country in South America. It is bordered by Argentina to the Argentina–Paraguay border, south and southwest, Brazil to the Brazil–Paraguay border, east and northeast, and Bolivia to the northwest. It has a population of around 6.1 million, nearly 2.3 million of whom live in the Capital city, capital and largest city of Asunción, and its surrounding metro area. Spanish conquistadores arrived in 1524, and in 1537 established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Reductions, Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. After the Suppression of the Society of Jesus, expulsion of the Jesuits from Spanish territories in 1767, Paraguay increasingly became a peripheral colony. Following Independence of Paraguay, independence from Spain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Pleistocene
The Early Pleistocene is an unofficial epoch (geology), sub-epoch in the international geologic timescale in chronostratigraphy, representing the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 annum, Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian, Gelasian Age and the Calabrian (stage), Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene respectively. The Chibanian provisionally spans time from 773 ka to 126 ka, and the Tarantian from then until the definitive end of the whole Pleistocene, c. 9700 BC in the 10th millennium BC. Notes {{Ge ...

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...
