The development of the saber-toothed condition appears to represent a shift in function and killing behavior, rather than one in predator-prey relations. Many hypotheses exist concerning saber-tooth killing methods, some of which include attacking soft tissue such as the belly and throat, where biting deep was essential to generate killing blows.
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. It is the animal from which the subfamily Machairodontinae gets its name.
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to mammals — fills a longstanding gap in the fossil record.

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).
Screengrab of Facebook video shared by Thailand's Department of National Parks, Wildlife and Plant Conservation Under the cover of darkness, a trio of predators walked through a forest in Thailand.
It compares the overkill hypothesis (predator hunting = 0) with second-order predation (predator hunting varied between 0.01 and 0.05 for different runs). The findings are that second-order predation is more consistent with extinction than is overkill [169] [170] (results graph at left). The Pleistocene extinction model is the only test of ...
