Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe, with the earliest species known from the Middle Miocene, with the last surviving species (belonging to the genera Smilodon and Homotherium) becoming extinct around Late Pleistocene-Holocene transition (~13-10,000 years ago).
The first fossils of this genus were described in 1846 by Richard Owen as the species Machairodus latidens. [3] The name Homotherium (Greek: ὁμός (homos, 'same') and θηρίον (therion, 'beast')) was proposed by Emilio Fabrini (1890), without further explanation, for a new subgenus of Machairodus, whose main distinguishing feature was the presence of a large diastema between the two ...
[25] [26] Smilodon is most famous for its relatively long canine teeth, which are the longest found in the saber-toothed cats, at about 28 cm (11 in) long in the largest species, S.populator. [25] The canines were slender and had fine serrations on the front and back side. [27] The skull was robustly proportioned and the muzzle was short and broad.
Saber-toothed predator. A saber-tooth (alternatively spelled sabre-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 ...
Homotherini (Machairodontini) is a tribe (or subtribe) [1] of saber-toothed cats of the family Felidae (true cats). The tribe is commonly known as scimitar-toothed cats.These saber-toothed cats were endemic to North America, Europe, Asia, Africa, and South America [2] from the Miocene to Pleistocene living from c. 23 Ma until c. 12,000 years ago.

The skull, designated D2280, indicates wounds to the occipital matching the dimensions of the sabre-teeth of Megantereon. From the position of the bite marks, it can be inferred that the hominid was attacked from the front and top of the skull, and that the bite was likely placed by a cat which saw the hominid as a threat.
A Siamese Cat named Rayne Beau (pronounced "rainbow) went missing while on a camping trip to Yellowstone National Park with his family. But after two months passed, he somehow managed to find his ...
Unlike most other saber-toothed cats, all of Xenosmilus ' s teeth were serrated, not just its fangs and incisors. Xenosmilus differs from Homotherium and most other cats in the lack of a gap separating the last incisor tooth and the canine, as well as the loss of the p3 tooth. Notably only the later species of Smilodon have also lost the p3 tooth.
