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
From top and from left to right, Inostrancevia, Hoplophoneus, Barbourofelis, Smilodon, Machaeroides and Thylacosmilus 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.
[4] [8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in North America, 83% in South America and 88% in Australia, [10] with all mammals over 1,000 kilograms (2,200 lb) becoming extinct in Australia and the Americas, [1] and around 80% globally.

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).
It was suggested that the material from the main islands is conspecific with the extant black swan, while that from the Chathams represents a truly different, extinct species.

Unfortunately, many factors have contributed to their decline, and conservation efforts are underway to ensure they don’t become extinct. Pollution The human effects on axolotls have been mostly ...
This is disputable as many big-game hunting predators such as Smilodon, great white sharks and Allosaurus have weaker bite forces and often laterally weak skulls as adaptations towards, not away from, killing large prey, relying instead on the presence of a cutting edge, a wide gape made possible by the reduction of jaw musculature, and the ...
