Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in every continent except for Australia and Antarctica. The earliest species is known from the Middle Miocene, while the latest species Smilodon populator survived up to the Early Holocene (8,200~9,100 years ago).

Machairodus (from Greek: μαχαίρα machaíra, 'knife' and Greek: ὀδούς odoús 'tooth') [2] is a genus of large machairodont or ''saber-toothed cat'' that lived in Africa, Eurasia and North America during the Late Miocene, from 12.5 million to 5.5 million years ago. It is the animal from which the subfamily Machairodontinae gets its name.
A new point-to-point bite model is introduced in the article by Andersson et al., showing that for saber-tooth cats, the depth of the killing bite decreases dramatically with increasing prey size. [10] The extended gape of saber-toothed cats results in a considerable increase in bite depth when biting into prey with a radius of less than 10 cm.
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 Middle Miocene to early Holocene, from 10.3 mya—8,200 years ago.
Scientists have discovered a pristine fossil of a mummified saber-toothed kitten that had been frozen in the Russian tundra for about 37,000 years.
Nimravidae is an extinct family of carnivorans, sometimes known as false saber-toothed cats, whose fossils are found in North America and Eurasia. Not considered to belong to the true cats (family Felidae ), the nimravids are generally considered closely related and classified as a distinct family in the suborder Feliformia .
Homotherium is an extinct genus of scimitar-toothed cat belonging to the extinct subfamily Machairodontinae that inhabited North America, Eurasia, and Africa (as well as possibly South America) during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago.
