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.
One of the best-known genera is the machairodont or "saber-toothed cat" Smilodon, the species of which, especially S. fatalis, are popularly referred to as "saber-toothed tigers", although they are not closely related to tigers . Despite some similarities, not all saber-tooths are closely related to saber-toothed cats or felids in-general
The biggest saber-toothed cats are Amphimachairodus kabir and Smilodon populator, with the males possibly reaching 350–490 kg (770–1,080 lb) and 220–450 kg (490–990 lb) respectively. [42] [183] [184] Another contender for the largest felid of all time is Machairodus.
In 2004 an experiment used a pair of mechanical aluminum jaws, cast from the CT scans of a Smilodon fatalis from the La Brea tar pits, to simulate several biting techniques possibly used by Smilodon, including the shearing bite, on a fresh domestic cow carcass. [61]
S. fatalis may have been impacted by habitat turnover and loss of prey it specialized on due to possible climatic plus anthropogenic impacts and other factors while the extinction of S. populator remains poorly understood." As long as the lede mainly reflects on the extinction of Smilodon in particular, we should be
