American Lion
''Panthera atrox'', better known as the American lion, also called the North American lion, or American cave lion, is an extinct pantherine cat that lived in North America during the Pleistocene epoch and the early Holocene epoch, about 340,000 to 11,000 years ago. Its fossils have been excavated from Alaska to Mexico. Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion (''Panthera spelaea'') are sister lineages. It was about 25% larger than the modern lion, making it one of the largest known felids. History and taxonomy Initial discovery and North American fossils The first specimen now assigned to ''Panthera atrox'' was collected in the 1830s and placed in the collection of by William Henry Huntingtion Esquire, who announced their discovery to the American Philosophical Society on April 1, 1836 and placed with other fossils from Huntington's collection in the Academy of Natural Sciences in Philadelphia. The specimen had been c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cougar
The cougar (''Puma concolor'') is a large Felidae, cat native to the Americas. Its Species distribution, range spans from the Canadian Yukon to the southern Andes in South America and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, Generalist and specialist species, generalist species, occurring in most American habitat types. This wide range has brought it many common names, including puma, mountain lion, catamount and panther (for the Florida sub-population). It is the second-largest cat in the New World, after the jaguar (''Panthera onca''). Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (''Felis catus'') than to any species of the subfamily Pantherinae. The cougar is an ambush predator that pursues a wide variety of pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lion
The lion (''Panthera leo'') is a large Felidae, cat of the genus ''Panthera'' native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called ''prides''. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex predator, apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt Human, humans, lions typically don't actively seek out and prey on humans. The lion inhabits grasslands, savannas and shrublands. It is usually more diurnality, diurnal than other wild cats, but when persecuted, it adapts to being active nocturnality, at night and crepuscular, at twilight. During the Neolithic period, the li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaguar
The jaguar (''Panthera onca'') is a large cat species and the only living member of the genus '' Panthera'' native to the Americas. With a body length of up to and a weight of up to , it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the 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 extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainfo ...

Panthera
''Panthera'' is a genus within the family (biology), family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (''P. tigris''), lion (''P. leo''), jaguar (''P. onca''), and leopard (''P. pardus'') on the basis of common Cranial bones, cranial features. Results of genetic analysis indicate that the snow leopard (formerly ''Uncia uncia'') also belongs to the genus ''Panthera'' (''P. uncia''), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, jaguar and leopard are the only cat species with anatomical structures that enable them to Roar (utterance), roar; the snow leopard cannot. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other Morphology (biology), morphological features, especiall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Campbell Merriam
John Campbell Merriam (October 20, 1869 – October 30, 1945) was an American paleontologist, educator, and conservationist. The first vertebrate paleontologist on the West Coast of the United States, he is best known for his taxonomy of vertebrate fossils at the La Brea Tar Pits in Los Angeles, particularly with the genus ''Smilodon'', more commonly known as the sabertooth cat. He is also known for his work to extend the reach of the National Park Service. Biography He was born in Hopkinton, Iowa, the eldest child of postmaster, store proprietor, and American Civil War veteran Charles E. Merriam.

Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.
