Panthera onca augusta is an extinct subspecies of the jaguar that was endemic to North America during the Last Glacial Maximum of the Pleistocene epoch. [1]
Although P. onca still resides in the southern United States and several Native American tales possibly about P. onca augusta exist, the first published remains were described in 1872. [2] The fossils were found by Ferdinand Vandeveer Hayden on the Platte River of Nebraska and sent to Joseph Leidy at the Academy of Natural Sciences in Philadelphia, who named them Felis augustus in 1872. The fossils consisted of a premolar IV and maxilla fragment, the type (USNM 1004), as well as another tooth and a distal humerus, though the humerus is likely that of Panthera atrox or Smilodon fatalis. Leidy also mistakenly believed the fossils were from the Pliocene, but they actually come from the Pleistocene. [3]
Later in 1919, Oliver Perry Hay described a left canine from Vero, Florida that he named Felis veronis, though it is now seen as a synonym of P. onca augusta. [3] In 1929, George Simpson referred several teeth from Seminole Field, Florida to F. veronis and the same year a right mandible and several teeth from Melbourne, Florida were collected by Dr. J. W. Gidley. All material found has been referred to P. onca augusta, the mandible notably was the first complete one found of the taxon. Yet another discovery came in 1938, with the discovery of 2 fragmentary postcranial skeletons of P. onca augusta in Cumberland Cave, Maryland intermingled with that of a puma.
The most productive discoveries outside of California came in 1939 and 1944, with the discoveries of footprints and several fossils in Craighead Caverns, Tennessee during the former year. [4] [3] 1944 saw the collection of 2, well preserved skeletons in Salt River Cave, also in Tennessee, that included 2 partial skulls and many axial elements that clearly demonstrated the subspecies’ clear differences with other taxa. [3] Many more fossils were later collected by the American Museum of Natural History at Craighead Caverns, including several mandibles and partial craniums. [4]
Additional fossils referable to P. onca augusta have been found in Oregon and, most notably, the La Brea Tar Pits of California. [5] [6] P. onca augusta is most frequently found in Florida’s localities, as there are many fossil-bearing sites from the Pleistocene throughout Florida. [3] [4] In 2021, a partial mandible was referred to P. onca augusta from Chapala, Mexico, extending the range south to southwestern Mexico. [7] A possible specimen of P. onca augusta is also known from Georgia, and mitogenomic analysis suggests that the specimen certainly belongs to P. onca, though its subspecific assignment remains unresolved.

The jaguar 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 1.85 m and a weight of up to 158 kg (348 lb), it is the biggest 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.
A black panther is the melanistic colour variant of the leopard and the jaguar. Black panthers of both species have excess black pigments, but their typical rosettes are also present. They have been documented mostly in tropical forests, with black leopards in Africa and Asia, and black jaguars in South America. Melanism is caused by a recessive allele in the leopard, and by a dominant allele in the jaguar.
Panthera is a genus within the family Felidae, and 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.
Smilodon is a genus of felids belonging to the extinct subfamily Machairodontinae. 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. 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 dire wolf is an extinct canine. The dire wolf lived in the Americas during the Late Pleistocene and Early Holocene epochs. The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized: Aenocyon dirus guildayi and Aenocyon dirus dirus. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles.
The American lion is an extinct pantherine cat native to North America during the Pleistocene epoch until around 12,800 years ago. Genetic evidence suggests that its closest living relative is the lion, with the American lion representing a derivative of the Eurasian cave lion, from which it is suggested to have split at least 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.
Miracinonyx is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch and morphologically similar to the modern cheetah, although its apparent similar ecological niches have been considered questionable due to anatomical morphologies of the former that would have limited the ability to act as a specialized pursuit predator. The genus was originally known from fragments of skeletons, but nearly complete skeletons have been recovered from Natural Trap Cave in northern Wyoming.
Craighead Caverns is an extensive cave system located in between Sweetwater and Madisonville, Tennessee. It is best known for containing the United States' largest and the world's second largest non-subglacial underground lake, The Lost Sea. In addition to the lake, the caverns contain an abundance of crystal clusters called anthodites, stalactites, stalagmites, and a waterfall.
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, but later also came to include the clouded leopards. 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.
Ronald John Clarke is a paleoanthropologist most notable for the discovery of "Little Foot", an extraordinarily complete skeleton of Australopithecus, in the Sterkfontein Caves. A more technical description of various aspects of his description of the Australopithecus skeleton was published in the Journal of Quaternary Science.
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.
Paramylodon is an extinct genus of ground sloth of the family Mylodontidae endemic to North America during the Pliocene through Pleistocene epochs, living from around ~4.9 Mya–12,000 years ago.
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.
Blue Spring Cave is a cave located in White County, Tennessee, on the north side of Blue Spring Cove. Blue Spring Cave is Tennessee's 2nd longest cave and the 10th longest cave in the United States.
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.
Protopithecus is an extinct genus of large New World monkey that lived during the Pleistocene. Fossils have been found in the Toca da Boa Vista cave of Brazil, as well as other locales in the country. Fossils of another large, but less robust ateline monkey, Caipora, were also discovered in Toca da Boa Vista.
Panthera pardus spelaea, also known as the European Ice Age leopard or the cave leopard, is a fossil leopard subspecies which roamed Europe in the Late Pleistocene and possibly the Holocene.
Gymnogyps amplus is an extinct species of large New World vulture in the family Cathartidae. The species was first described by Loye H. Miller (1911) in 1911 from a partial tarsometatarsus recovered from Pleistocene cave deposits in Samwel Cave of northern California. Harvey I. Fisher (1944) designated a set of plesiotypes from the Rancho La Brea which includes a cranium, rostrum, and mandible.
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.
