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
Lund was the first to describe dozens of species of Pleistocene megafauna, including the saber-toothed cat Smilodon populator. He also made the then ground-breaking discovery that humans co-existed with long-extinct animal species, something which possibly prompted him to terminate his scientific work.
Reconstruction of a Smilodon The evolution of enlarged canines in Tertiary carnivores was a result of large mammals being the source of prey for saber-toothed predators. The development of the saber-toothed condition appears to represent a shift in function and killing behavior, rather than one in predator-prey relations.
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.

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).
This is comparable in size to the much later Smilodon populator. [15] Its skull, measuring upwards of 16 inches (41 cm) in length, is one of the largest known skulls for any machairodont, with only a recently described S. populator skull rivaling it in size, with the latter cat outweighing M. horribilis at 960 lb (440 kg).
