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.
Panthera is a genus within the family Felidae, specifically known as 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, as well as a number of extinct species.
The term "big cat" is typically used to refer to any of the five living members of the genus Panthera, namely the tiger, lion, jaguar, leopard, and snow leopard, as well as the non-pantherine cheetah and cougar.
Proailurus is an extinct felid genus that lived in Europe and Asia approximately 25-30.8 million years ago in the Late Oligocene and Miocene. Fossils have been found in Mongolia, Germany, and Spain.
Pseudaelurus is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago. It is considered to be a paraphyletic grade ancestral to living felines and pantherines as well as the extinct machairodonts (saber-tooths), and is a successor to Proailurus. It originated from Eurasia and was the first cat to reach North America, when it entered the continent at about 18.5 Ma ending a 'cat-gap' of 7 million years. The slender proportions of the animal, together with its short, viverrid-like legs, suggest that it may have been an agile climber of trees.
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.
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.
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 Cave, Slovakia. Some records were also reported from Africa and Asia. P. gombaszoegensis was a medium-large sized species that formed an important part of the European carnivore guild for a period of over a million years. Many authors have posited that it is the ancestor of the American jaguar, with some authors considering it the subspecies Panthera onca gombaszoegensis, though the close relationship between the two species has been questioned.
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.
Puma pardoides is an extinct prehistoric cat in the cougar genus Puma known from fossils found across Eurasia.
Panthera zdanskyi is an extinct pantherine species, the fossils of which were excavated in Gansu Province, northwestern China. Due to its close relationship with the modern tiger, it is called the Longdan tiger.
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.
Styriofelis is an extinct genus of Felidae known from the Miocene of Europe.
Panthera shawi is an extinct prehistoric cat, of which a single canine tooth was excavated in Sterkfontein cave in South Africa by Robert Broom in the 1940s. It is thought to be the oldest known Panthera species in Africa.
Miopanthera is an extinct genus of Pseudaelurus-grade felids.
Sivaelurus is a fossil genus of felid containing only a single species, S. chinjiensis, which was described based on a partial right maxilla collected from the Chinji Formation in the Lower Siwaliks. The species was originally described by Guy Ellcock Pilgrim as Pseudaelurus chinjiensis in 1910, who later erected a new genus, Sivaelurus, for it in 1913.
Panthera balamoides is a species described as an extinct species of the big cat genus Panthera that is known from a single fossil found in a Late Pleistocene age cenote in the Yucatan Peninsula, Mexico. P. balamoides has only a single reported specimen, the distal end of a right humerus, that is notably of exceptional size for a felid. It was unearthed in 2012 from an underwater cave and described in 2019 by an international group of paleontologists from Mexico and Germany led by Sarah R. Stinnesbeck. However, several authors have since proposed that the fossil comes from an ursid, possibly the extinct Arctotherium, and not of felid affinities.
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.
Pachypanthera is an extinct genus of pantherine felid that was recovered from the Late Miocene-aged Khorat sand pits in northeastern Thailand. It contains a single species, Pachypanthera piriyai, named and described in 2023.
