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.
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.
This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and the Code for Viruses) require them. However, absolute ranks are not required in all nomenclatural systems for taxonomists; for instance, the PhyloCode , [ 2 ] the code of phylogenetic ...
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 ...
A male Amphimachairodus giganteus was one of the largest machairodonts. It dwarfs its modern relative, the common house cat, Felis catus. Based on mitochondrial DNA sequences extracted from fossils, machairodontines diverged from the ancestors of living cats around 20 million years ago, with the last surviving machairodont genera Homotherium and Smilodon estimated to have diverged from each ...
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
