Felidae is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid. The term "cat" refers both to felids in general and specifically to the domestic cat.
The lion 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. The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, lions typically do not actively seek out and prey on humans.
Panthera 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, lion, jaguar, and leopard on the basis of common cranial features. Results of genetic analysis indicate that the snow leopard also belongs to the genus Panthera, a classification that was accepted by IUCN Red List assessors in 2008.
Dinofelis is an extinct genus of machairodontine, usually classified in the tribe Metailurini. It was widespread in Europe, Asia, Africa and North America from 5 million to about 1.2 million years ago. Fossils very similar to Dinofelis from Lothagam range back to around 8 million years ago, in the Late Miocene.
Homotherium is an extinct genus of machairodontine scimitar-toothed cat that inhabited North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago. In comparison to Smilodon, the canines of Homotherium were shorter, and it was probably adapted to running down rather than ambushing prey.
Panthera spelaea, also known as the 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. Genetic analysis of ancient DNA has revealed that while closely related, it was distinct species genetically isolated from the modern lion occurring in Africa and Asia, with the genetic divergence between the two species variously estimated between 1.9 million and 600,000 years ago. It is closely related and probably ancestral to the American lion. The species ranged from Western Europe to eastern Beringia in North America, and was a prominent member of the mammoth steppe fauna. It became extinct about 13,000 years ago.
Panthera atrox, better known as the American lion, also called the North American lion, or American cave lion, is an extinct pantherine cat. Panthera atrox lived in North America during the Pleistocene epoch, from around 340,000 to 12,800 years ago. The species was initially described by American paleontologist Joseph Leidy in 1853 based on a fragmentary mandible (jawbone) from Mississippi; the species name ('atrox') means "savage" or "cruel". The status of the species is debated, with some mammalogists and paleontologists considering it a distinct species or a subspecies of Panthera leo, which contains living lions. However, novel genetic evidence has shown that it is instead a distinct species derived from the Eurasian cave or steppe lion, evolving after its geographic isolation in North America. Its fossils have been excavated from Alaska to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids.
The Pantherinae is a subfamily of the Felidae; it was named and first described by Reginald Innes Pocock in 1917 as only including the Panthera species. The Pantherinae genetically diverged from a common ancestor between 9.32 to 4.47 million years ago and 10.67 to 3.76 million years ago.
Megantereon was a genus of prehistoric machairodontine saber-toothed cat that lived in North America, Eurasia, and Africa. It is closely related to and possibly the ancestor of Smilodon.
The history of lions in Europe is based on fossils of Pleistocene and Holocene lions excavated in Europe since the early 19th century. The first lion fossil was excavated in southern Germany, and described by Georg August Goldfuss using the scientific name Felis spelaea. It probably dates to the Würm glaciation, and is 191,000 to 57,000 years old. Older lion skull fragments were excavated in Germany and described by Wilhelm von Reichenau under Felis fossilis in 1906. These are estimated at between 621,000 and 533,000 years old. The modern lion inhabited parts of Southern Europe since the early Holocene.
Panthera gombaszoegensis, also known as the European jaguar, is a Panthera species that lived from about 2.0 to 0.35 million years ago in Europe. The first fossils were excavated in 1938 in Gombasek, Slovakia.
Panthera youngi is a fossil cat species that was described in 1934; fossil remains of this cat were excavated in a Homo erectus formation in Choukoutien, northeastern China. Upper and lower jaws excavated in Japan's Yamaguchi Prefecture were also attributed to this species. It is estimated to have lived about 350,000 years ago in the Pleistocene epoch. It was suggested that it was conspecific with Panthera atrox and P. spelaea due to their extensive similarities. Some dental similarities were also noted with the older P. fossilis, however, Panthera youngi showed more derived features.
Panthera palaeosinensis was an early Pleistocene species from northern China. It is often incorrectly referenced as the ancestor of the tiger, Panthera tigris, although it shares features with all living large cats. Recent studies place it close to the base of the genus Panthera.
Panthera 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.
Amphimachairodus is an extinct genus of large machairodonts. It is also a member of the tribe Homotherini within Machairodontinae and is most closely related to such species as Xenosmilus, Homotherium itself, and Nimravides. It inhabited Eurasia, Northern Africa and North America during the late Miocene epoch.
Panthera blytheae is an extinct species of pantherine felid that lived during the late Messinian to early Zanclean ages approximately 5.95–4.1 million years ago.The first fossils were excavated in August 2010 in the Zanda Basin located in the Ngari Prefecture on the Tibetan Plateau; they were described and named in 2014.
Bolt's Farm is a palaeontological site in the Cradle of Humankind World Heritage Site, Gauteng province, South Africa. With more than 30 fossil deposits dating back 4.5 Ma, it is one of the oldest sites currently discovered in the Cradle of Humankind. It consists of multiple cavities, pits, and quarries, where caves have eroded away, exposing their fossiliferous interiors. Although this site has not yet yielded the hominid fossils for which the Cradle of Humankind is known, Bolt's Farm is still an important source of fossils from various species of Early Pliocene and Plio-Pleistocene fauna, including primates and big cats.
Panthera uncia pyrenaica, also known as the Arago snow leopard or as the European snow leopard, is a subspecies of snow leopard that lived during the Middle Pleistocene in southern France.
Panthera principialis is an extinct species in big cat genus Panthera described in 2023 based on fragmentary Pliocene-aged fossils from Laetoli, Tanzania. As the species was the oldest known Panthera species at the time, it was given the specific epithet "principialis", from the Latin word meaning "initial, original, in the beginning".
Puma incurva is an extinct species in genus Puma. It was described based on fossils from the Early Pleistocene-aged Swartkrans site in South Africa.
