Quaternary extinction eventThe latter half of the Late Pleistocene to the beginning of the Holocene (~50,000-10,000 years Before Present) saw extinctions of numerous predominantly megafaunal species, which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by the widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence.
PantheraPanthera is a genus within the 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 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.
Great American InterchangeThe Great American Biotic Interchange (commonly abbreviated as GABI), also known as the Great American Interchange and the Great American Faunal Interchange, was an important late Cenozoic paleozoogeographic biotic interchange event in which land and freshwater fauna migrated from North America via Central America to South America and vice versa, as the volcanic Isthmus of Panama rose up from the sea floor and bridged the formerly separated continents. Although earlier dispersals had occurred, probably over water, the migration accelerated dramatically about 2.
Panthera fossilisPanthera fossilis (also known as Panthera leo fossilis or Panthera spelaea fossilis), is an extinct species of cat belonging to the genus Panthera, known from remains found in Eurasia spanning the Middle Pleistocene and possibly into the Early Pleistocene. P. fossilis has sometimes been referred to by the common names steppe lion or cave lion, though these names are conventionally restricted to the later related species P. spelaea, to which P. fossilis is probably ancestral.
MachairodontinaeMachairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe from the Miocene to the Pleistocene, living from about 16 million until about 11,000 years ago. The Machairodontinae contain many of the extinct predators commonly known as "saber-toothed cats", including the famed genus Smilodon, as well as other cats with only minor increases in the size and length of their maxillary canines.
Panthera spelaeaPanthera spelaea, also known as the Eurasian cave lion, European cave lion or steppe lion, is an extinct Panthera species that most likely evolved in Europe after the third Cromerian interglacial stage, less than 600,000 years ago. Phylogenetic analysis of fossil bone samples revealed that it was highly distinct and genetically isolated from the modern lion (Panthera leo) occurring in Africa and Asia. Analysis of morphological differences and mitochondrial data support the taxonomic recognition of Panthera spelaea as a distinct species that genetically diverged from the lion about .
American Museum of Natural HistoryThe American Museum of Natural History (abbreviated as A.M.N.H) is a natural history museum on the Upper West Side of Manhattan in New York City. Located in Theodore Roosevelt Park, across the street from Central Park, the museum complex comprises 20 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library.
MegafaunaIn zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over (i.e., having a mass comparable to or larger than a human) or weighing over a tonne, (i.e., having a mass comparable to or larger than an ox). The first of these include many species not popularly thought of as overly large, and being the only few large animals left in a given range/area, such as white-tailed deer, Thomson's gazelle, and red kangaroo.
FelidaeFelidae (ˈfɛlᵻdiː) is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid (ˈfiːlɪd). The term "cat" refers both to felids in general and specifically to the domestic cat (Felis catus). The 41 Felidae species exhibit the most 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.
LionThe lion (Panthera leo) is a large 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.
