† Smilodon fatalis: Over 2.000 individuals represented by more than 130.000 specimens. Smilodon is among the most well-known mammals from Rancho La Brea and the second most common carnivore found in the pits, only behind the dire wolf. Unlike the American lion, which is a true cat, Smilodon was a member of the Machairodontinae.
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).
Xenosmilus is in the tribe Homotherini in the subfamily Machairodontinae of the cat family. [1] A paper published in 2022 proposed that Xenosmilus is a more derived member of the tribe Machairodontini (another name for Homotherini), and that Homotherium venezuelensis should be reassigned to Xenosmilus, [11] with a 2024 paper arguing that remains from Uruguay should also be assigned to the ...
[1] † Smilodon gracilis [22] [23] Few fragmentary specimens, including a partial skull. Smilodon is among the most well-known mammals from the Ice Age, but S. gracilis is far smaller than later species. S. gracilis was described on the basis of a canine from Port Kennedy by Cope in 1880 and was the ancestor to Rancholabrean species.
The fossils consisted of a premolar IV and maxilla fragment, the type (USNM 1004), as well as another tooth and a distal humerus, though the humerus is likely that of Panthera atrox or Smilodon fatalis. Leidy also mistakenly believed the fossils were from the Pliocene, but they actually come from the Pleistocene. [3]
