This study estimated body mass across the species of Smilodon using regression relationships between skeletal dimensions and body weight in living felids. The analysis confirmed that the South America…

This study recovered ancient DNA from extinct North American cats, including the scimitar-toothed Homotherium and the cheetah-like Miracinonyx, to test their relationships against living felids. The g…

This study recovered complete mitochondrial genomes from the dirk-toothed Smilodon and the scimitar-toothed Homotherium, allowing a genetic test of how these iconic sabertooths relate to one another a…

This systematic study examined the North American species long grouped under Pseudaelurus, the assemblage of stem cats that bridged the earliest felids and the later radiation of modern cats and saber…

This authoritative review chapter synthesizes the evolutionary history and phylogeny of the cat family, integrating fossil evidence with molecular data to present a comprehensive picture of how cats d…

This overview surveys Hyperailurictis, the name applied to the North American Pseudaelurus-grade cats that represent the first true felids to colonize the continent after the cat gap. Arriving from Eu…

This overview examines the Nimravidae, an extinct family of cat-like carnivores that independently evolved sabertooth forms long before the true machairodont cats. Though strikingly similar to felids…

This overview examines Smilodon populator, the largest known sabertooth cat, which roamed the plains and woodlands of Pleistocene South America after felids crossed the Panamanian land bridge. Body-ma…

This overview examines the evolutionary geography of the cheetah lineage and its New World relatives. Molecular and fossil evidence indicate that the cheetah-puma group has a complex transatlantic his…

This overview examines how body size influenced which carnivores survived the end-Pleistocene extinctions and which, like the great cats, did not. Large predators tend to have smaller populations, low…

This overview surveys what the claw anatomy of sabertooth cats reveals about how they handled prey. Like living felids, machairodonts had retractile claws, but in robust dirk-toothed forms such as Smi…

This overview examines the evolutionary relationships of Miracinonyx and the now well-supported conclusion that its cheetah-like form arose through convergence rather than common ancestry with the tru…

This overview surveys dental microwear texture analysis, a method that examines microscopic wear features on tooth surfaces to infer what an animal ate shortly before death. In fossil cats, the techni…

This overview examines one of the defining trends in felid evolution: the progressive loss and simplification of teeth from the relatively full dentition of Proailurus to the highly reduced tooth row…

This overview examines the exceptionally powerful forelimbs of Smilodon and what they reveal about how the cat subdued prey. Compared with similarly sized living felids, Smilodon shows thickened limb…

This overview surveys the bony chin flanges, or mandibular flanges, found in many sabertooth carnivores, including barbourofelids and the marsupial-relative Thylacosmilus, and in reduced form in some…

This overview surveys efforts to sequence nuclear and mitochondrial genomes from Homotherium and what they reveal about the scimitar cat's place among felids. Ancient DNA recovered from Pleistocene sp…

This overview reviews what the preserved hyoid bones of Smilodon suggest about the sounds the sabertooth may have made. In living cats, the structure of the hyoid apparatus correlates with whether a s…

This overview synthesizes the striking pattern by which a sabertooth body plan evolved repeatedly and independently across unrelated lineages of predatory mammals. True cats (machairodonts), nimravids…

This overview addresses how sabertooths like Smilodon achieved the enormous gape needed to clear their elongated canines and apply them to prey. Estimates suggest the jaws could open to roughly twice…

This overview reviews evidence that the scimitar-toothed cat Homotherium latidens persisted in Europe far later than once believed. A well-known mandible dredged from the floor of the North Sea, dated…

This overview reviews what the skeletons of the earliest cats, especially Proailurus and early Pseudaelurus-grade forms, reveal about their locomotion and likely habits. Features such as relatively lo…

This overview examines mesowear and other gross tooth-wear approaches as applied to extinct cats, which assess the cumulative shape and rounding of cusps to infer long-term dietary abrasiveness and ca…

This overview reviews the quantitative methods palaeontologists use to estimate the body mass of extinct cats such as Smilodon, Homotherium, and Panthera atrox. Because soft tissue is not preserved, r…

This overview compares the killing strategies of sabertooth cats with those of conical-toothed felids such as modern lions and tigers. Living big cats typically use short, robust canines and a powerfu…

This overview examines whether Smilodon fatalis showed pronounced size differences between males and females, a question with implications for its social system. Because the La Brea sample is large, r…

This overview surveys the stable isotope techniques used to reconstruct the diets of extinct cats. Carbon isotopes in bone and tooth collagen and enamel record whether prey fed on plants using differe…

This overview explains why the Rancho La Brea asphalt seeps preserve such an extraordinary concentration of sabertooths and other carnivores. Natural petroleum seeping to the surface forms sticky asph…

This overview examines the central role of the Bering land bridge in the history of cats, serving as a recurrent corridor for felid movement between Asia and North America. The survey reviews how lowe…

This overview surveys the Pseudaelurus-grade cats, a diverse assemblage of stem felids that flourished across Eurasia and North America during the Miocene and bridged the dawn cat Proailurus and the l…
