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.

Prehistoric Predators is a 2007 National Geographic Channel program based on different predators that lived in the Cenozoic era, including Smilodon and C. megalodon.The series investigated how such beasts hunted and fought other creatures, and what drove them to extinction.
Smilodon / ˈ s m aɪ l ə d ɒ n /, is an extinct genus of machairodont felid. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats. Smilodon lived in the Americas during the Pleistocene epoch (2.5 mya–10,000 years ago). The genus was named in 1842, based on fossils from Brazil.
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

Other differences include the canine saber teeth of Megantereon lacking serrations (present on those of Smilodon) [10] the posterior border of the nasal region being less flat and the zygomatic arch being less upwardly arched and wider than that of Smilodon, and the mastoid process lacking the exaggerated development present in Smilodon.

Smilodon fatalis and Aenocyon dirus fight over a Mammuthus columbi carcass in the La Brea Tar Pits, risking becoming trapped themselves. A predator trap is a natural hazard where prey animals become trapped or incapacitated, and the attracted predators suffer the same fate. More predators, scavengers, insects and birds become attracted to this ...
