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.
The Knife Tooth Cat (Machairodus) is a genus of large machairodont or ''saber-toothed cat'' that lived in Africa, Eurasia and North America during the late Miocene. It is the animal from which the subfamily Machairodontinae gets its name and has since become a wastebasket taxon over the years as many genera of sabertooth cat have been and are still occasionally lumped into it.
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.
A saber-tooth is any member of various extinct groups of predatory therapsids, predominantly carnivoran mammals, that are characterized by long, curved saber-shaped canine teeth which protruded from the mouth when closed. Saber-toothed mammals have been found almost worldwide from the Eocene epoch to the end of the Pleistocene epoch.
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae. 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 10,000 years ago.
Smilodontini is an extinct tribe within the Machairodontinae or "saber-toothed cat" subfamily of the Felidae. The tribe is also known as the "dirk-toothed cats". They were endemic to South America, North America, Europe, Asia, and Africa during the Miocene to Pleistocene, from 10.3 mya—11,000 years ago, existing for approximately 10.3 million years.
Paramachaerodus is an extinct genus of saber-tooth cat of the subfamily Machairodontinae, which was endemic to Eurasia during the Middle and Late Miocene from 15 to 9 Ma. A 2022 phylogenetic analysis suggested that the genus may be polyphyletic.
Megantereon is an extinct 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.
Barbourofelis is an extinct genus of large, predatory, feliform carnivoran mammals of the family Barbourofelidae. The genus was endemic to North America and Eurasia during the Miocene until its extinction during the Tortonian, living from 13.6 to 4.9 Ma.
Protictitherium is an extinct genus of hyena that lived across Europe and Asia during the Middle and Late Miocene, it is often considered to be the first hyena since it contains some of the oldest fossils of the family. They were especially prolific in Turkey, where every species has been registered.
Nimravides is a genus of extinct saber-toothed cats that lived in North America during the Late Miocene, between 10.3 and 5.332 Ma. Despite its scientific name, Nimravides does not belong to the Nimravidae, but is a true cat belonging to the family Felidae.
Agnotherium is a genus of large sized carnivoran mammals, belonging to the Amphicyonidae, which has been found in Western Europe, and possibly China and Northern Africa, and lived during the Late Miocene epoch. Despite only being known from fragmentary remains, the genus notable for hypercarnivorous adaptions, which have been said to represent the "apex" among its family.
Cerro de los Batallones is a hill at Torrejón de Velasco, Madrid, Spain where a number of fossil sites from the Upper Miocene (MN10) have been found. Nine sites have been discovered with predominantly vertebrate fossils, invertebrates and plants being less represented. The first deposits were discovered accidentally in July 1991.
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.
Yoshi is an extinct genus of machairodontine sabertooth cat in the tribe Metailurini. Its fossils were described from Turolian deposits from the Miocene epoch of the Balkan Peninsula in 2014 and specimens from China once thought to belong to Metailurus. The name comes from that of the lead author's pet cat. It has been described as potentially being synonymous with Metailurus, though this is difficult to confirm at present. The type specimen is a skull that bears remarkable similarities with the modern cheetah. Yoshi is intermediate in size between a lynx and cougar, and based on several as-yet unpublished skeletons, may have had a similar lifestyle to the cheetah, being better built for speed and fast pursuit than most other machairodonts, which were more suited to ambush and hunting large, relatively slow moving animals.
Magericyon is an extinct genus of Amphicyonid ("bear-dog") that lived during the Miocene 10-9 Ma in what is now Spain.
Styriofelis is an extinct genus of Felidae known from the Miocene of Europe.
Leptofelis is an extinct genus of Pseudaelurus-grade felid found in Spain.
Leontoceryx is an extinct, little-known genus of pantherine felid. It was named in 1938 by Hungarian palaeontologist Miklós Kretzoi based on a partial upper jaw fossil with only three teeth present.
Ammitocyon is a genus of large sized carnivoran mammals, belonging to the Amphicyonidae, that lived during the Late Miocene in what is now Spain. It is notable for its extreme adaptations towards hypercarnivory, its extremely robust skeleton, and was one of the last surviving members of its family.
