The tiger is a large cat and a member of the genus Panthera native to Asia. It has a powerful, muscular body with a large head and paws, a long tail and orange fur with black, mostly vertical stripes. It is traditionally classified into nine recent subspecies, though some recognise only two subspecies, mainland Asian tigers and the island tigers of the Sunda Islands.
The leopard is one of the five extant cat species in the genus Panthera. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of 92–183 cm (36–72 in) with a 66–102 cm (26–40 in) long tail and a shoulder height of 60–70 cm (24–28 in). Males typically weigh 30.9–72 kg (68–159 lb), and females 20.5–43 kg (45–95 lb).
Smilodon is an extinct genus of felids. It is one of the best known saber-toothed predators and prehistoric mammals. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats, belonging to the extinct subfamily Machairodontinae, with an estimated date of divergence from the ancestor of living cats around 20 million years ago. Smilodon was one of the last surviving machairodonts alongside Homotherium. Smilodon lived in the Americas during the Pleistocene epoch. The genus was named in 1842 based on fossils from Brazil; the generic name means "scalpel" or "two-edged knife" combined with "tooth". Three species are recognized today: S. gracilis, S. fatalis, and S. populator. The two latter species were probably descended from S. gracilis, which itself probably evolved from Megantereon. The hundreds of specimens obtained from the La Brea Tar Pits in Los Angeles constitute the largest collection of Smilodon fossils.
The Bengal tiger or Royal Bengal tiger is a population of the Panthera tigris tigris subspecies and the nominate tiger subspecies. It ranks among the biggest wild cats alive today. It is estimated to have been present in the Indian subcontinent since the Late Pleistocene for about 12,000 to 16,500 years. Its historical range covered the Indus River valley until the early 19th century, almost all of India, western Pakistan, southern Nepal, Bangladesh, Bhutan and southwestern China. Today, it inhabits India, Bangladesh, Nepal, Bhutan, and southwestern China. It is threatened by poaching, habitat loss and habitat fragmentation.
Solo Man is a subspecies of H. erectus that lived along the Solo River in Java, Indonesia, about 117,000 to 108,000 years ago in the Late Pleistocene. This population is the last known record of the species. It is known from 14 skullcaps, two tibiae, and a piece of the pelvis excavated near the village of Ngandong, and possibly three skulls from Sambungmacan and a skull from Ngawi depending on classification. The Ngandong site was first excavated from 1931 to 1933 under the direction of Willem Frederik Florus Oppenoorth, Carel ter Haar, and Gustav Heinrich Ralph von Koenigswald, but further study was set back by the Great Depression, World War II and the Indonesian War of Independence. In accordance with historical race concepts, Indonesian H. erectus subspecies were originally classified as the direct ancestors of Aboriginal Australians, but Solo Man is now thought to have no living descendants because the remains far predate modern human immigration into the area, which began roughly 55,000 to 50,000 years ago.
Panthera spelaea, commonly known as the cave lion, is an extinct Panthera species that was native to Eurasia and northwest North America during the Pleistocene epoch. Genetic analysis of ancient DNA has revealed that while closely related, it was a distinct species genetically isolated from the modern lion, with the genetic divergence between the two species estimated at around 500,000 years ago. The earliest fossils of the P. spelaea lineage in Eurasia date to around 700,000 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, and an important apex predator across its range. It became extinct about 13,000 years ago. It closely resembled living lions with a coat of yellowish-grey fur though unlike extant lions, males appear to have lacked manes.
The American lion, with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 130,000 to 12,800 years ago. Genetic evidence suggests that its closest living relative is the lion, with the American lion representing an offshoot from the lineage of the largely Eurasian cave lion, from which it is suggested to have split around 165,000 years ago. Its fossils have been found across North America, from Canada to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids to ever exist, and an important apex predator.
The Sumatran tiger is a population of Panthera tigris sondaica on the Indonesian island of Sumatra. It is the only surviving tiger population in the Sunda Islands, where the Bali and Javan tigers are extinct.
The Javan tiger was a Panthera tigris sondaica population native to the Indonesian island of Java. It was one of the three tiger populations that colonized the Sunda Islands during the last glacial period 110,000–12,000 years ago. It used to inhabit most of Java, but its natural habitat decreased continuously due to conversion for agricultural land use and infrastructure. By 1940, it had retreated to remote montane and forested areas. Since no evidence of a Javan tiger was found during several studies in the 1980s and 1990s, it was assessed as being extinct in 2008.
The Bali tiger was a Panthera tigris sondaica population on the Indonesian island of Bali which has been extinct since the 1950s. It was formerly regarded as a distinct tiger subspecies with the scientific name Panthera tigris balica, which had been assessed as extinct on the IUCN Red List in 2008. In 2017, felid taxonomy was revised, and it was subordinated to P. t. sondaica, which also includes the still surviving Sumatran tiger.
The Malayan tiger is a tiger from a specific population of the Panthera tigris tigris subspecies that is native to Peninsular Malaysia. This population inhabits the southern and central parts of the Malay Peninsula, and has been classified as critically endangered. As of April 2014, the population was estimated at 80–120 mature individuals, with a continuing downward trend.
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 tigris trinilensis, known as the Trinil tiger, is an extinct tiger subspecies dating from about 1.2 million years ago that was found at the locality of Trinil, Java, Indonesia. The fossil remains are now stored in the Dubois Collection of the National Museum of Natural History in Leiden, the Netherlands. Although these fossils have been found on Java, the Trinil tiger is probably not a direct ancestor of the Javan tiger. The Trinil tiger probably became extinct 50,000 years ago. The Bali tiger was also not closely related to the Trinil because of their time differences.
Homo erectus is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Its specimens are among the first recognizable members of the genus Homo.
Panthera onca mesembrina, also known as the Patagonian panther, is an extinct subspecies of jaguar 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.
Panthera tigris acutidens or Wanhsien tiger is an extinct tiger subspecies, which was scientifically described in 1928 based on fossils excavated near Wanhsien in southern China's Sichuan Province. Otto Zdansky named it Felis acutidens. After the fossils were re-examined in 1947, they were attributed to Panthera tigris acutidens by Dirk Albert Hooijer and Walter W. Granger.
Hemimachairodus is an extinct genus of machairodontine (sabre-toothed) cat with only one species, Hemimachairodus zwierzyckii, known from fossils from the Pleistocene of Java.
The region of Southeast Asia is considered a possible place for the evidence of archaic human remains that could be found due to the pathway between Australia and mainland Southeast Asia, where the migration of multiple early humans has occurred out of Africa. One of many pieces of evidence is of the early human found in central Java of Indonesia in the late 19th century by Eugene Dubois, and later in 1937 at Sangiran site by G.H.R. van Koenigswald. These skull and fossil materials are Homo erectus, named Pithecanthropus erectus by Dubois and Meganthropus palaeojavanicus by van Koenigswald. They were dated to c. 1.88 and 1.66 Ma, as suggested by Swisher et al. by analysis of volcanic rocks.
The Bornean tiger or Borneo tiger is possibly an extinct tiger population that lived on the island of Borneo in prehistoric times.
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 one of the oldest known Panthera species in Africa.
