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
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.
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] [184] [185] Another contender for the largest felid of all time is Machairodus.
Smilodon fatalis, Arctotherium bonariense, Canis nehringi, maned wolves, and humans would have also joined this predator guild at various stages of the Lujanian. [ 19 ] [ 33 ] [ 34 ] However, a fragmented Arctotherium c.f. tarijense tooth from Baño Nuevo-1 cave in southern Chile preserves cavities, which could be interpreted as a consequence ...
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
This is comparable in size to the much later Smilodon populator. [20] 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 A. horribilis at 960 lb (440 kg). [21] [22]
The best specimens for this species are its lower jaw, a single skull, and teeth, which carry intermediate characteristics between advanced forms such as Smilodon and primitive forms such as Paramachairodus. Based on the mandible alone, Rhizosmilodon has the primitive traits traits: a large lower canine and a small but evident jaw flange. The ...
